  26 [1] System requirements
  27 =======================
  28
  29     A) Linux
  30
  31     Any Linux distribution will support smartmontools if it has a
  32     kernel version greater than or equal to 2.2.14. So any recent
  33     Linux distribution should support smartmontools.
  34
  35     B) FreeBSD
  36
  37     For FreeBSD support, a 5-current kernel that includes ATAng is
  38     required in order to support ATA drives.  Even current versions of
  39     ATAng will not support 100% operation, as the SMART status can not
  40     be reliably retrieved.  There is patch pending approval of the
  41     ATAng driver maintainer that will address this issue.
  42
  43     C) Solaris
  44
  45     The SCSI code has been tested on a variety of Solaris 8 and 9
  46     systems.  ATA/IDE code only works on SPARC platform.  All tested
  47     kernels worked correctly.
  48
  49     D) NetBSD/OpenBSD
  50
  51     The code was tested on a 1.6ZG (i.e., 1.6-current) system. It should
  52     also function under 1.6.1 and later releases (unverified).  Currently
  53     it doesn't support ATA devices on 3ware RAID controllers.
  54
  55     E) Cygwin
  56
  57     The code was tested on Cygwin 2.9.0-3 x86 and x86_64. It should also
  58     work on other recent releases.
  59
  60     Both Cygwin and Windows versions of smartmontools share the same code
  61     to access the IDE/ATA or SCSI devices. The information in the "Windows"
  62     section below also applies to the Cygwin version.
  63
  64     F) Windows
  65
  66     The code was tested on Windows XP SP3, 2003, Vista, Windows 7, 8, 8.1
  67     and Windows 10 up to 1709.  Support von Windows 9x/ME and NT4 was
  68     removed after smartmontools 5.43.
  69
  70     ATA or SATA devices are supported if the device driver implements
  71     the SMART IOCTLs or IOCTL_IDE_PASS_THROUGH or IOCTL_ATA_PASS_THROUGH.
  72     Only the latter provides full pass-through support which is needed
  73     for all smartmontools features.
  74
  75     SATA devices behind a Intel RST driver are accessed through CSMI.
  76
  77     SCSI and USB devices are accessed through SPTI. Special driver support
  78     is not required.
  79
  80     G) MacOS/Darwin
  81
  82     The code was tested on MacOS 10.3.4.  It should work from 10.3
  83     forwards.  It doesn't support 10.2.
  84
  85     It's important to know that on 10.3.x, some things don't work
  86     (see WARNINGS): due to bugs in the libraries used, you cannot run
  87     a short test or switch SMART support off on a drive; if you try,
  88     you will just run an extended test or switch SMART support on.  So
  89     don't panic when your "short" test seems to be taking hours.
  90
  91     It's also not possible at present to control when the offline
  92     routine runs. If your drive doesn't have it running automatically by
  93     default, you can't run it at all.
  94
  95     SCSI devices are not currently supported.  Detecting the power
  96     status of a drive is also not currently supported.
  97
  98     To summarize this, from another point of view, the things that
  99     are not supported fall into two categories:
 100
 101    * Can't be implemented easily without more kernel-level support,
 102      so far as I know:
 103      - running immediate offline, conveyance, or selective tests
 104      - running any test in captive mode
 105      - aborting tests
 106      - switching automatic offline testing on or off
 107      - support for SCSI
 108      - checking the power mode [-n Directive of smartd] (this is not
 109        completely impossible, but not by using a documented API)
 110
 111    * Work on 10.4 and later, but not on 10.3:
 112      - switching off SMART (switching *on* works fine)
 113      - switching off auto-save (but why would you want to?)
 114      - running the short test (that leaves you with only the extended test)
 115
 116     However, some things do work well.  For ATA devices, all the
 117     informational output is available, unless you want something that only
 118     an offline test updates.  On many newer Mac OS systems, the
 119     hard drive comes with the offline test switched on by default, so
 120     even that works.
 121
 122     The OS X SAT SMART Driver provides access to SMART data for SAT capable
 123     USB and Firewire devices:
 124     https://github.com/kasbert/OS-X-SAT-SMART-Driver
 125     https://github.com/RJVB/OS-X-SAT-SMART-Driver
 126     This does not require any smartctl -d TYPE option and should work also
 127     with older smartmontools releases.
 128
 129     H) OS/2, eComStation
 130
 131     The code was tested on eComStation 1.1, but it should work on all versions
 132     of OS/2.
 133     Innotek LibC 0.5 runtime is required.
 134     Only ATA disks are supported.
 135
 136 [2] Installing from SVN
 137 =======================
 138
 139     Get the sources from the SVN repository:
 140     svn co http://svn.code.sf.net/p/smartmontools/code/trunk/smartmontools smartmontools
 141
 142     Then type:
 143     ./autogen.sh
 144     and continue with step [3] below, skipping the "unpack the tarball" step.
 145
 146     The autogen.sh command is ONLY required when installing from
 147     SVN. You need GNU Autoconf (version 2.60 or greater), GNU Automake
 148     (version 1.10 or greater) and their dependencies installed in order
 149     to run it.
 150
 151 [3] Installing from the source tarball
 152 ======================================
 153
 154     If you are NOT installing from SVN, then unpack the tarball:
 155     tar zxvf smartmontools-5.VERSION.tar.gz
 156
 157     Then:
 158     ./configure
 159     make
 160     make install (you may need to be root to do this)
 161
 162     As shown (with no options to ./configure) this defaults to the
 163     following set of installation directories and other settings:
 164
 165     --prefix=/usr/local
 166     --exec-prefix='${prefix}'
 167     --sbindir='${exec_prefix}/sbin'
 168     --sysconfdir='${prefix}/etc'
 169     --localstatedir='${prefix}/var'
 170     --datarootdir='${prefix}/share'
 171     --datadir='${datarootdir}'
 172     --mandir='${datarootdir}/man'
 173     --docdir='${datarootdir}/doc/smartmontools'
 174     --disable-sample
 175     --with-systemdsystemunitdir=auto
 176     --with-systemdenvfile=auto
 177     --with-initscriptdir=auto
 178     --with-exampledir='${docdir}/examplescripts'
 179     --with-drivedbdir='${datadir}/smartmontools'
 180     --with-update-smart-drivedb
 181     --with-gnupg
 182     --with-smartdscriptdir='${sysconfdir}'
 183     --with-smartdplugindir='${smartdscriptdir}/smartd_warning.d'
 184     --with-scriptpath='/bin:/usr/bin'
 185     --without-savestates
 186     --without-attributelog
 187     --with-os-deps='os_linux.o dev_areca.o' (platform specific)
 188     --without-selinux
 189     --with-libcap-ng=auto
 190     --without-nvme-devicescan
 191     --without-solaris-sparc-ata (Solaris SPARC only)
 192     --with-working-snprintf (Windows: guessed)
 193     --with-mingw-aslr=auto (Windows only)
 194     --with-cxx11-option=auto
 195
 196     These will usually not overwrite existing "distribution" installations on
 197     Linux Systems since the FHS reserves this area for use by the system
 198     administrator.
 199
 200     For different installation locations or distributions, simply add
 201     arguments to ./configure as shown in [4] below.
 202
 203     If you wish to alter the default C++ compiler flags, add
 204     CXXFLAGS='your options' to ./configure command.
 205
 206     The first output line of smartctl and smartd provides information
 207     about release number, last SVN checkin date and revison, platform,
 208     and package. The latter defaults to "(local build)" and can be
 209     changed by the variable BUILD_INFO, for example:
 210     make BUILD_INFO='"(Debian 5.39-2)"'
 211
 212 [4] Guidelines for different Linux distributions
 213 ================================================
 214
 215 Note: Please send corrections/additions to:
 216 smartmontools-support@listi.jpberlin.de
 217
 218 Debian:
 219   If you don't want to overwrite any distribution package, use:
 220   ./configure
 221
 222 Filesystem Hierarchy Standard (FHS, http://www.pathname.com/fhs/):
 223   ./configure --sbindir=/usr/local/sbin                               \
 224               --sysconfdir=/usr/local/etc                             \
 225               --mandir=/usr/local/man                                 \
 226               --docdir=/usr/local/share/doc/smartmontools             \
 227               --with-initscriptdir=/usr/local/etc/init.d
 228
 229 Red Hat:
 230   ./configure --sbindir=/usr/sbin                               \
 231               --sysconfdir=/etc                                 \
 232               --mandir=/usr/share/man                           \
 233               --docdir=/usr/share/doc/smartmontools             \
 234               --with-initscriptdir=/etc/rc.d/init.d
 235
 236 Slackware:
 237   If you don't want to overwrite any "distribution" package, use:
 238   ./configure
 239
 240   Otherwise use:
 241   ./configure --sbindir=/usr/sbin                               \
 242               --sysconfdir=/etc                                 \
 243               --mandir=/usr/share/man                           \
 244               --docdir=/usr/share/doc/smartmontools             \
 245               --with-initscriptdir=/etc/rc.d
 246
 247   And
 248   removepkg smartmontools smartsuite (only root can do this)
 249   before make install
 250
 251   The init script works on Slackware. You just have to add an entry like
 252   the following in /etc/rc.d/rc.M or /etc/rc.d/rc.local:
 253
 254   if [ -x /etc/rc.d/smartd ]; then
 255     . /etc/rc.d/smartd start
 256   fi
 257
 258   To disable it:
 259   chmod 644 /etc/rc.d/smartd
 260
 261   For a list of options:
 262   /etc/rc.d/smartd
 263
 264 SuSE:
 265   ./configure --sbindir=/usr/sbin                                        \
 266               --sysconfdir=/etc                                          \
 267               --mandir=/usr/share/man                                    \
 268               --docdir=/usr/share/doc/packages/smartmontools-VERSION     \
 269               --with-initscriptdir=/etc/init.d                           \
 270
 271 [5] Guidelines for FreeBSD
 272 ==========================
 273   To match the way it will installed when it becomes available as a PORT, use
 274   the following:
 275
 276   ./configure --prefix=/usr/local                                      \
 277               --docdir=/usr/local/share/doc/smartmontools-VERSION      \
 278               --with-initscriptdir=/usr/local/etc/rc.d/                \
 279               --enable-sample
 280
 281   NOTE: --enable-sample will cause the smartd.conf and smartd RC files to
 282   be installed with the string '.sample' append to the name, so you will end
 283   up with the following:
 284         /usr/local/etc/smartd.conf.sample
 285         /usr/local/etc/rc.d/smartd.sample
 286
 287
 288 [6] Guidelines for Darwin
 289 =========================
 290   ./configure --with-initscriptdir=/Library/StartupItems
 291
 292   If you'd like to build the i386 version on a powerpc machine, you can
 293   use
 294
 295   CXX='g++ -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386' \
 296     ./configure --host=i386-apple-darwin \
 297                 --with-initscriptdir=/Library/StartupItems
 298
 299 [7] Guidelines for NetBSD
 300 =========================
 301   ./configure --prefix=/usr/pkg                                       \
 302               --docdir=/usr/pkg/share/doc/smartmontools
 303
 304 [8] Guidelines for Solaris
 305 ==========================
 306
 307     smartmontools has been partially but not completely ported to
 308     Solaris.  It includes complete SCSI support but no ATA or 3ware
 309     support.  It can be compiled with either CC (Sun's C++ compiler)
 310     or GNU g++.
 311
 312     To compile with g++:
 313
 314     ./configure [args]
 315     make
 316
 317     To compile with Sun CC:
 318
 319     env CC=cc CXX=CC ./configure [args]
 320     make
 321
 322     The correct arguments [args] to configure are:
 323      --sbindir=/usr/sbin                                \
 324      --sysconfdir=/etc                                  \
 325      --mandir=/usr/share/man                            \
 326      --docdir=/usr/share/doc/smartmontools-VERSION      \
 327      --with-initscriptdir=/etc/init.d
 328
 329     To start the script automatically on bootup, create hardlinks that
 330     indicate when to start/stop in:
 331                     /etc/rc[S0123].d/
 332     pointing to /etc/init.d/smartd. Create:
 333             K<knum>smartd in rcS.d, rc0.d, rc1.d, rc2.d
 334             S<snum>smartd in rc3.d
 335     where <knum> is related to <snum> such that the higher snum is the
 336     lower knum must be.
 337
 338     On usual configuration, '95' would be suitable for <snum> and '05'
 339     for <knum> respectively.  If you choose these value, you can
 340     create hardlinks by:
 341
 342     cd /etc
 343     sh -c 'for n in S 0 1 2; do ln init.d/smartd rc$n.d/K05smartd; done'
 344     sh -c 'for n in 3      ; do ln init.d/smartd rc$n.d/S95smartd; done'
 345
 346 [9] Guidelines for Cygwin
 347 =========================
 348
 349 Same as Red Hat:
 350   ./configure --prefix=/usr                 \
 351               --sysconfdir=/etc             \
 352               --mandir='${prefix}/share/man'
 353
 354   OR EQUIVALENTLY
 355   ./configure --sbindir=/usr/sbin                               \
 356               --sysconfdir=/etc                                 \
 357               --mandir=/usr/share/man                           \
 358               --docdir=/usr/share/doc/smartmontools             \
 359               --with-initscriptdir=/etc/rc.d/init.d
 360
 361   Using DOS text file type as default for the working directories ("textmode"
 362   mount option) is not recommended. Building the binaries and man pages using
 363   "make" is possible, but "make dist" and related targets work only with UNIX
 364   file type ("binmode" mount option) set. The "autogen.sh" script prints a
 365   warning if DOS type is selected.
 366
 367   Files may also be checked out with a non-Cygwin SVN client which uses CR/LF
 368   for svn:eol-style=native.  The "autogen.sh" script has svn:eol-style=LF.
 369   Bash option "-o igncr" is not required.
 370
 371 [10] Guidelines for Windows
 372 ===========================
 373
 374 To compile statically linked Windows release with MinGW gcc on MSYS, use:
 375
 376   ./configure
 377   make
 378
 379   Instead of using "make install", copy the .exe files into
 380   some directory in the PATH.
 381
 382 Cross-compile statically linked 32-bit and 64-bit versions with MinGW-w64:
 383
 384   ./configure --build=$(./config.guess) \
 385               --host=i686-w64-mingw32
 386
 387   ./configure --build=$(./config.guess) \
 388               --host=x86_64-w64-mingw32
 389
 390   Tested on Cygwin, Debian and Fedora.
 391
 392
 393 To build the Windows binary distribution, use:
 394
 395   make dist-win32
 396
 397   This builds the distribution in directory
 398
 399   ./smartmontools-VERSION.win32/
 400
 401   and packs it into
 402
 403   ./smartmontools-VERSION.win32.zip
 404
 405 To create a Windows installer, use:
 406
 407   make installer-win32
 408
 409   This builds the distribution directory and packs it into the
 410   self-extracting install program
 411
 412   ./smartmontools-VERSION.win32-setup.exe
 413
 414   The installer is build using the command "makensis" from the NSIS
 415   package. See http://nsis.sourceforge.net/ for documentation and
 416   download location.
 417
 418   It is also possible to (cross-)build the installer on Linux.
 419   This was successfully tested on Debian and Fedora with package
 420   "nsis".
 421
 422 To create a combined 32-/64-bit installer, use this in 32-bit build
 423 directory if 64-build directory is at ../build64:
 424
 425   make builddir_win64=../build64 installer_win32
 426
 427 To both create and run the (interactive) installer, use:
 428
 429   make install-win32
 430
 431   Additional make targets are distdir-win32 to build the directory
 432   only and cleandist-win32 for cleanup.
 433
 434   The binary distribution includes all documentation files converted
 435   to DOS text file format and *.html and *.txt preformatted man pages.
 436
 437 To prepare os_win32/vc14 directory for MS Visual Studio C++ 2015 builds,
 438 use the following on MSYS or Cygwin:
 439
 440   mkdir vctmp && cd vctmp
 441   ../configure [... any MinGW option set from above ...]
 442   make config-vc14
 443
 444   The MSVC project files (os_win32/vc14/*) are included in SVN (but not
 445   in source tarball). The target config-vc14 from a Makefile configured
 446   for MinGW creates os_win32/vc14/{config.h,smart*.rc,svnversion.h}.
 447   The configure skript must be run outside of the source directory to
 448   avoid inclusion of the original config.h.

 451 [11] Guidelines for OS/2, eComStation
 452 =====================================
 453
 454 To compile the OS/2 code, please run
 455
 456   ./configure
 457   make
 458   make install
 459
 460 [12] Guidelines for OpenBSD
 461 ===========================
 462   To match the way it will installed when it becomes available as a PORT, use
 463   the following:
 464
 465   ./configure --prefix=/usr/local                                      \
 466               --sysconfdir=/etc                                        \
 467               --docdir=/usr/local/share/doc/smartmontools-VERSION      \
 468               --without-initscriptdir                                  \
 469               --enable-sample
 470
 471   NOTE: --enable-sample will cause the smartd.conf and smartd RC files to
 472   be installed with the string '.sample' append to the name, so you will end
 473   up with the following:
 474         /etc/smartd.conf.sample
 475
 476 [13] Comments
 477 ============
 478
 479 To compile from another directory, you can replace the step
 480   ./configure [options]
 481 by the following:
 482   mkdir objdir
 483   cd objdir
 484   ../configure [options]
 485
 486 Man pages contents is platform-specific by default. Info specific to other
 487 platforms may be not visible. To generate man pages with full contents use:
 488
 489   make os_man_filter=
 490
 491 To install to another destination (used mainly by package maintainers,
 492 or to examine the package contents without risk of modifying any
 493 system files) you can replace the step:
 494   make install
 495 with:
 496   make DESTDIR=/home/myself/smartmontools-package install
 497
 498 Use a full path. Paths like ./smartmontools-package may not work.
 499
 500 After installing smartmontools, you can read the man pages, and try
 501 out the commands:
 502
 503 man smartd.conf
 504 man smartctl
 505 man smartd
 506
 507 /usr/sbin/smartctl -s on -o on -S on /dev/sda (only root can do this)
 508 /usr/sbin/smartctl -a /dev/sda (only root can do this)
 509
 510 Note that the default location for the manual pages are
 511 /usr/share/man/man5 and /usr/share/man/man8.  If "man" doesn't find
 512 them, you may need to add /usr/share/man to your MANPATH environment
 513 variable.
 514
 515 Source and binary packages for Windows are available at
 516 http://sourceforge.net/projects/smartmontools/files/
 517
 518 Refer to http://www.smartmontools.org/wiki/Download for any additional
 519 download and installation instructions.
 520
 521 The following files are installed if ./configure has no options:
 522
 523 /usr/local/sbin/smartctl                                [Executable command-line utility]

 542
 543 Due to checks done by '--with-systemdsystemunitdir=auto' and '--with-initscriptdir=auto',
 544 one of the following files may also be installed:
 545
 546 /usr/local/lib/systemd/system/smartd.service            [Systemd service file for smartd]
 547 /usr/local/etc/rc.d/init.d/smartd                       [Init/Startup script for smartd]
 548 /usr/local/etc/init.d/smartd                            [Init/Startup script for smartd]
 549 /usr/local/etc/rc.d/smartd                              [Init/Startup script for smartd]
 550
 551 If /usr/local/etc/smartd.conf exists and differs from the
 552 default then the default configuration file is installed as
 553 /usr/local/etc/smartd.conf.sample instead.
 554
 555 The commands:
 556
 557 make htmlman
 558 make pdfman
 559 make txtman
 560
 561 may be used to build .html, .pdf and .txt preformatted man pages.
 562 These are used by the dist-win32 make target to build the Windows
 563 distribution.
 564 The commands also work on other operating system configurations
 565 if suitable versions of man, man2html and groff are installed.
 566 On systems without man2html, the following command should work
 567 if groff is available:
 568
 569 make MAN2HTML='groff -man -Thtml' htmlman
 570
 571
 572 Some of the source files are prepared for the documentation
 573 generator Doxygen (http://www.doxygen.org/). If Doxygen is installed,
 574 the command:
 575
 576 doxygen
 577
 578 creates HTML documentation in doc/html and LaTeX documentation
 579 in doc/latex. If TeX is installed, the following command creates
 580 a documentation file doc/latex/refman.pdf:
 581
 582 ( cd doc/latex && make pdf )
 583

 585 [14] Detailed description of arguments to configure command
 586 ===========================================================
 587
 588 When you type:
 589 ./configure --help
 590 a description of available configure options is printed
 591 [with defaults in square brackets].  See also section [3] above.
 592
 593
 594 The following old configure options are no longer supported:
 595
 596 Old option                 Replacement
 597 --with-docdir=DIR          --docdir=DIR (autoconf >= 2.60)
 598 --enable-drivedb           [no option needed]
 599 --disable-drivedb          --without-drivedbdir
 600 --enable-savestates        --with-savestates[=yes]
 601 --disable-savestates       [no option needed]
 602 --enable-attrbutelog       --with-attributelog[=yes]
 603 --disable-savestates       [no option needed]
 604
 605
 606 The defaults for --with-initscriptdir and --with-systemdsystemunitdir are
 607 guessed such that the following rules apply:
 608 - If --prefix=/usr --sysconfdir=/etc is specified, the guessed directories
 609   should be the defaults used by the current OS or distribution.
 610 - If --sysconfdir=/etc is NOT specified, the guessed directories should
 611   always be below ${prefix} or below ${sysconfdir}.
 612
 613 Here's an example:
 614 If you set --prefix=/home/joe and none of the other four
 615 variables then the different directories that are used would be:
 616 --sbindir             /home/joe/sbin
 617 --docdir              /home/joe/share/doc/smartmontools
 618 --mandir              /home/joe/share/man
 619 --sysconfdir          /home/joe/etc
 620 --with-exampledir     /home/joe/share/doc/smartmontools/examplescripts
 621 --with-drivedbdir     /home/joe/share/smartmontools
 622 --with-initscriptdir         [see below]
 623 --with-systemdsystemunitdir  [see below]
 624
 625 If systemd is present (and pkg-config reports /lib/systemd/system
 626 as the systemdsystemunitdir):
 627
 628 --with-initscriptdir         [disabled]
 629 --with-systemdsystemunitdir  /home/joe/lib/systemd/system
 630
 631 else if /etc/rc.d/init.d exists:
 632
 633 --with-initscriptdir         /home/joe/etc/rc.d/init.d
 634 --with-systemdsystemunitdir  [disabled]
 635
 636 else if /etc/init.d exists:
 637
 638 --with-initscriptdir         /home/joe/etc/init.d
 639 --with-systemdsystemunitdir  [disabled]
 640
 641 else if /etc/rc.d exists:
 642
 643 --with-initscriptdir         /home/joe/etc/rc.d
 644 --with-systemdsystemunitdir  [disabled]
 645
 646 else
 647
 648 --with-initscriptdir         [disabled]
 649 --with-systemdsystemunitdir  [disabled]
 650
 651
 652 Here are the differences with and without --enable-sample, assuming
 653 that initscript location is set and no other options specified
 654 (see above for details)
 655
 656 Case 1:
 657 --enable-sample provided
 658 ==> Files installed are:
 659         /usr/local/etc/smartd.conf.sample
 660         /usr/local/etc/rc.d/init.d/smartd.sample
 661
 662 Case 2:
 663 --disable-sample provided or parameter left out
 664 ==> Files installed are:
 665         /usr/local/etc/smartd.conf
 666         /usr/local/etc/rc.d/init.d/smartd
