| 2 | FreeBSD Implementation details | |

| 8 | ||
| 9 | Current implementation works on ZFS pools | |
| 10 | ||
| 11 | * created in /var/lib/ceph | |
| 12 | * One ZFS pool per OSD, like:: | |
| 13 | ||
| 14 | gpart create -s GPT ada1 | |
| 15 | gpart add -t freebsd-zfs -l osd1 ada1 | |
| 16 | zpool create -o mountpoint=/var/lib/ceph/osd/osd.1 osd | |
| 17 | ||
| 18 | * Maybe add some cache and log (ZIL)? Assuming that ada2 is an SSD:: | |

| 7c673cae FG |
20 | gpart create -s GPT ada2 |
| 21 | gpart add -t freebsd-zfs -l osd1-log -s 1G ada2 | |
| 22 | zpool add osd1 log gpt/osd1-log | |
| 23 | gpart add -t freebsd-zfs -l osd1-cache -s 10G ada2 | |
| 24 | zpool add osd1 log gpt/osd1-cache | |
| 25 | ||
| 26 | * Note: *UFS2 does not allow large xattribs* | |
| 27 | ||

| 29 | Configuration | |
| 30 | ------------- | |
| 31 | ||
| 32 | As per FreeBSD default parts of extra software go into ``/usr/local/``. Which | |
| 11fdf7f2 | 33 | means that for ``/etc/ceph.conf`` the default location is |
| 7c673cae FG |
34 | ``/usr/local/etc/ceph/ceph.conf``. Smartest thing to do is to create a softlink |
| 35 | from ``/etc/ceph`` to ``/usr/local/etc/ceph``:: | |
| 36 | ||
| 37 | ln -s /usr/local/etc/ceph /etc/ceph | |
| 11fdf7f2 | 38 | |
| 7c673cae FG |
39 | A sample file is provided in ``/usr/local/share/doc/ceph/sample.ceph.conf`` |
| 40 | ||
| 41 | ||
| 42 | MON creation | |
| 43 | ------------ | |
| 44 | ||
| 45 | Monitors are created by following the manual creation steps on:: | |

| 50 | OSD creation | |
| 51 | ------------ | |
| 52 | ||
| 11fdf7f2 | 53 | OSDs can be manually created only, see :ref:`freebsd_adding_osds` |
