832b75ed | 39 | \fB/usr/local/etc/smartd.conf\fP is the configuration file for the \fBsmartd\fP |
ee38a438 | 40 | daemon. |
832b75ed GG |
41 | |
42 | If the configuration file \fB/usr/local/etc/smartd.conf\fP is present, | |
43 | \fBsmartd\fP reads it at startup, before \fBfork\fP(2)ing into the | |
44 | background. If \fBsmartd\fP subsequently receives a \fBHUP\fP signal, | |
45 | it will then re-read the configuration file. If \fBsmartd\fP is | |
46 | running in debug mode, then an \fBINT\fP signal will also make it | |
47 | re-read the configuration file. This signal can be generated by typing | |
48 | \fB\<CONTROL-C\>\fP in the terminal window where \fBsmartd\fP is | |
49 | running. | |
50 | ||
d008864d | 51 | In the absence of a configuration file |
ee38a438 GI |
52 | \fBsmartd\fP will try to open all available devices |
53 | (see \fBsmartd\fP(8) man page). | |
54 | A configuration file with a single line \fB\'DEVICESCAN \-a'\fP | |
55 | would have the same effect. | |
832b75ed GG |
56 | |
57 | This can be annoying if you have an ATA or SCSI device that hangs or | |
58 | misbehaves when receiving SMART commands. Even if this causes no | |
ee38a438 GI |
59 | problems, you may be annoyed by the string of error log messages about devices |
60 | that can\'t be opened. | |
832b75ed GG |
61 | |
62 | One can avoid this problem, and gain more control over the types of | |
63 | events monitored by | |
64 | \fBsmartd\fP, | |
65 | by using the configuration file | |
66 | .B /usr/local/etc/smartd.conf. | |
67 | This file contains a list of devices to monitor, with one device per | |
68 | line. An example file is included with the | |
69 | .B smartmontools | |
70 | distribution. You will find this sample configuration file in | |
e9583e0c | 71 | \fB/usr/local/share/doc/smartmontools/\fP. For security, the configuration file |
832b75ed GG |
72 | should not be writable by anyone but root. The syntax of the file is as |
73 | follows: | |
74 | .IP \(bu 4 | |
75 | There should be one device listed per line, although you may have | |
76 | lines that are entirely comments or white space. | |
77 | .IP \(bu 4 | |
78 | Any text following a hash sign \'#\' and up to the end of the line is | |
79 | taken to be a comment, and ignored. | |
80 | .IP \(bu 4 | |
81 | Lines may be continued by using a backslash \'\e\' as the last | |
82 | non-whitespace or non-comment item on a line. | |
83 | .IP \(bu 4 | |
84 | Note: a line whose first character is a hash sign \'#\' is treated as | |
85 | a white-space blank line, \fBnot\fP as a non-existent line, and will | |
86 | \fBend\fP a continuation line. | |

cfbba5b9 GI |
489 | [ATA only] This \'nocheck\' Directive is used to prevent a disk from |
490 | being spun-up when it is periodically polled by \fBsmartd\fP. | |
832b75ed GG |
491 | |
492 | ATA disks have five different power states. In order of increasing | |
493 | power consumption they are: \'OFF\', \'SLEEP\', \'STANDBY\', \'IDLE\', | |
494 | and \'ACTIVE\'. Typically in the OFF, SLEEP, and STANDBY modes the | |
495 | disk\'s platters are not spinning. But usually, in response to SMART | |
496 | commands issued by \fBsmartd\fP, the disk platters are spun up. So if | |
ee38a438 GI |
497 | this option is not used, then a disk which is in a low-power mode may |
498 | be spun up and put into a higher-power mode when it is periodically | |
832b75ed GG |
499 | polled by \fBsmartd\fP. |
500 | ||
501 | Note that if the disk is in SLEEP mode when \fBsmartd\fP is started, | |
502 | then it won't respond to \fBsmartd\fP commands, and so the disk won't | |
503 | be registered as a device for \fBsmartd\fP to monitor. If a disk is in | |
ee38a438 GI |
504 | any other low-power mode, then the commands issued by \fBsmartd\fP to |
505 | register the disk will probably cause it to spin-up. | |
832b75ed GG |
506 | |
507 | The \'\fB\-n\fP\' (nocheck) Directive specifies if \fBsmartd\fP\'s | |
508 | periodic checks should still be carried out when the device is in a | |
ee38a438 | 509 | low-power mode. It may be used to prevent a disk from being spun-up |
832b75ed GG |
510 | by periodic \fBsmartd\fP polling. The allowed values of POWERMODE |
511 | are: | |
512 | ||
513 | .I never | |
514 | \- \fBsmartd\fP will poll (check) the device regardless of its power | |
ee38a438 | 515 | mode. This may cause a disk which is spun-down to be spun-up when |
832b75ed GG |
516 | \fBsmartd\fP checks it. This is the default behavior if the '\-n' |
517 | Directive is not given. | |
518 | ||
519 | .I sleep | |
520 | \- check the device unless it is in SLEEP mode. | |
521 | ||
522 | .I standby | |
523 | \- check the device unless it is in SLEEP or STANDBY mode. In | |
524 | these modes most disks are not spinning, so if you want to prevent | |
525 | a laptop disk from spinning up each time that \fBsmartd\fP polls, | |
526 | this is probably what you want. | |
527 | ||
528 | .I idle | |
529 | \- check the device unless it is in SLEEP, STANDBY or IDLE mode. | |
530 | In the IDLE state, most disks are still spinning, so this is probably | |
531 | not what you want. | |
532 | ||
2127e193 GI |
533 | Maximum number of skipped checks (in a row) can be specified by |
534 | appending positive number \',N\' to POWERMODE (like \'\-n standby,15\'). | |

785 | \fBREGEXP\fP. By default the regularly-scheduled device polling | |
786 | occurs every thirty minutes after starting \fBsmartd\fP. Take caution | |
787 | if you use the \'\-i\' option to make this polling interval more than | |
788 | sixty minutes: the poll times may fail to coincide with any of the | |

806 | that you constructed \fBREGEXP\fP correctly. The matching order | |
807 | (\fBL\fP before \fBS\fP before \fBC\fP before \fBO\fP) ensures that | |
808 | if multiple test types are all scheduled for the same hour, the | |
809 | longer test type has precedence. This is usually the desired behavior. | |

941 | \- send additional warning reminder emails, after a one-day interval, | |
942 | then a two-day interval, then a four-day interval, and so on for each | |
943 | type of disk problem detected. Each interval is twice as long as the | |
944 | previous interval. | |

1296 | A pending sector is a disk sector (containing 512 bytes of your data) |

1300 | inconsistent Error Checking and Correction (ECC) codes. This is | |
1301 | important to know, because it means that there is some unreadable data | |
1302 | on the disk. The problem of figuring out what file this data belongs | |
1303 | to is operating system and file system specific. You can typically | |
1304 | force the sector to reallocate by writing to it (translation: make the | |
1305 | device substitute a spare good sector for the bad one) but at the | |
1306 | price of losing the 512 bytes of data stored there. | |

1439 | The valid arguments to this Directive are: | |
832b75ed GG |
1440 | |
1441 | .I use | |
1442 | \- use any presets that are available for this drive. This is the default. | |

1461 | .B \'\-f\' | |
1462 | to report failures of Usage (rather than Prefail) Attributes, | |
1463 | .B \'\-t\' | |
1464 | to track changes in both Prefailure and Usage Attributes, | |
d008864d | 1465 | .B \'\-l\ error\' |
832b75ed | 1466 | to report increases in the number of ATA errors, |
d008864d GI |
1467 | .B \'\-l\ selftest\' |
1468 | to report increases in the number of Self-Test Log errors, | |
1469 | .B \'\-l\ selfteststs\' | |
1470 | to report changes of Self-Test execution status, | |
832b75ed GG |
1471 | .B \'\-C 197\' |
1472 | to report nonzero values of the current pending sector count, and | |
1473 | .B \'\-U 198\' | |
1474 | to report nonzero values of the offline pending sector count. | |
1475 | ||
1476 | Note that \-a is the default for ATA devices. If none of these other | |
1477 | Directives is given, then \-a is assumed. | |

1487 | If you are not sure which Directives to use, I suggest experimenting | |
1488 | for a few minutes with | |
1489 | .B smartctl | |
1490 | to see what SMART functionality your disk(s) support(s). If you do | |
1491 | not like voluminous syslog messages, a good choice of | |
1492 | \fBsmartd\fP | |
1493 | configuration file Directives might be: | |
1494 | .nf | |
1495 | .B \-H \-l\ selftest \-l\ error \-f. | |
1496 | .fi | |
1497 | If you want more frequent information, use: | |
1498 | .B -a. | |

1501 | .B ADDITIONAL DETAILS ABOUT DEVICESCAN | |
7f0798ef | 1502 | If a non-comment entry in the configuration file is the text |
832b75ed GG |
1503 | string \fBDEVICESCAN\fP in capital letters, then \fBsmartd\fP will |
1504 | ignore any remaining lines in the configuration file, and will scan | |
ee38a438 | 1505 | for devices (see also \fBsmartd\fP(8) man page). |
7f0798ef | 1506 | |
832b75ed GG |
1507 | If \fBDEVICESCAN\fP is not followed by any Directives, then smartd |
1508 | will scan for both ATA and SCSI devices, and will monitor all possible | |
1509 | SMART properties of any devices that are found. | |
1510 | ||
1511 | \fBDEVICESCAN\fP may optionally be followed by any valid Directives, | |
1512 | which will be applied to all devices that are found in the scan. For | |
1513 | example | |
1514 | .nf | |
1515 | .B DEVICESCAN -m root@example.com | |
1516 | .fi | |
1517 | will scan for all devices, and then monitor them. It will send one | |
1518 | email warning per device for any problems that are found. | |
1519 | .nf | |
1520 | .B DEVICESCAN -d ata -m root@example.com | |
1521 | .fi | |
1522 | will do the same, but restricts the scan to ATA devices only. | |
1523 | .nf | |
1524 | .B DEVICESCAN -H -d ata -m root@example.com | |
1525 | .fi | |
1526 | will do the same, but only monitors the SMART health status of the | |
1527 | devices, (rather than the default \-a, which monitors all SMART | |
1528 | properties). | |
1529 | ||
ee38a438 GI |
1530 | [NEW EXPERIMENTAL SMARTD FEATURE] |
1531 | Configuration entries for specific devices may precede the \fBDEVICESCAN\fP entry. | |
1532 | For example | |
1533 | .nf | |
1534 | .B DEFAULT -m root@example.com | |
1535 | .B /dev/sda -s S/../.././02 | |
1536 | .B /dev/sdc -d ignore | |
1537 | .B DEVICESCAN -s L/../.././02 | |
1538 | .fi | |
1539 | will scan for all devices except /dev/sda and /dev/sdc, monitor them, and run a long | |
1540 | test between 2-3am every morning. Device /dev/sda will also be monitored, but | |
1541 | only a short test will be run. Device /dev/sdc will be ignored. | |
1542 | Warning emails will be sent for all monitored devices. | |

1545 | .B EXAMPLES OF SHELL SCRIPTS FOR \'\-M exec\' | |
1546 | These are two examples of shell scripts that can be used with the \'\-M | |
1547 | exec PATH\' Directive described previously. The paths to these scripts | |
1548 | and similar executables is the PATH argument to the \'\-M exec PATH\' | |
1549 | Directive. | |
1550 | ||
1551 | Example 1: This script is for use with \'\-m ADDRESS -M exec PATH\'. It appends | |
1552 | the output of | |
1553 | .B smartctl -a | |
1554 | to the output of the smartd email warning message and sends it to ADDRESS. | |
1555 | ||
1556 | .nf | |
1557 | \fB | |
1558 | #! /bin/bash | |
1559 | ||
1560 | # Save the email message (STDIN) to a file: | |
1561 | cat > /root/msg | |
1562 | ||
1563 | # Append the output of smartctl -a to the message: | |
1564 | /usr/local/sbin/smartctl -a -d $SMART_DEVICETYPE $SMARTD_DEVICE >> /root/msg | |
1565 | ||
1566 | # Now email the message to the user at address ADD: | |
1567 | /bin/mail -s "$SMARTD_SUBJECT" $SMARTD_ADDRESS < /root/msg | |
1568 | \fP | |
1569 | .fi | |
1570 | ||
1571 | Example 2: This script is for use with \'\-m <nomailer> \-M exec | |
1572 | PATH\'. It warns all users about a disk problem, waits 30 seconds, and | |
1573 | then powers down the machine. | |
1574 | ||
1575 | .nf | |
1576 | \fB | |
1577 | #! /bin/bash | |
1578 | ||
1579 | # Warn all users of a problem | |
1580 | wall \'Problem detected with disk: \' "$SMARTD_DEVICESTRING" | |
1581 | wall \'Warning message from smartd is: \' "$SMARTD_MESSAGE" | |
1582 | wall \'Shutting down machine in 30 seconds... \' | |
1583 | ||
1584 | # Wait half a minute | |
1585 | sleep 30 | |
1586 | ||
1587 | # Power down the machine | |
1588 | /sbin/shutdown -hf now | |
1589 | \fP | |
1590 | .fi | |
1591 | ||
1592 | Some example scripts are distributed with the smartmontools package, | |
e9583e0c | 1593 | in /usr/local/share/doc/smartmontools/examplescripts/. |
832b75ed GG |
1594 | |
1595 | Please note that these scripts typically run as root, so any files | |
1596 | that they read/write should not be writable by ordinary users or | |
1597 | reside in directories like /tmp that are writable by ordinary users | |
1598 | and may expose your system to symlink attacks. | |
1599 | ||
1600 | As previously described, if the scripts write to STDOUT or STDERR, | |
1601 | this is interpreted as indicating that there was an internal error | |
1602 | within the script, and a snippet of STDOUT/STDERR is logged to SYSLOG. | |
1603 | The remainder is flushed. | |
