============================== FreeBSD Implementation details ============================== Disk layout ----------- Current implementation works on ZFS pools * created in /var/lib/ceph * One ZFS pool per OSD, like:: gpart create -s GPT ada1 gpart add -t freebsd-zfs -l osd1 ada1 zpool create -o mountpoint=/var/lib/ceph/osd/osd.1 osd * Maybe add some cache and log (ZIL)? Assuming that ada2 is an SSD:: gpart create -s GPT ada2 gpart add -t freebsd-zfs -l osd1-log -s 1G ada2 zpool add osd1 log gpt/osd1-log gpart add -t freebsd-zfs -l osd1-cache -s 10G ada2 zpool add osd1 log gpt/osd1-cache * Note: *UFS2 does not allow large xattribs* Configuration ------------- As per FreeBSD default parts of extra software go into ``/usr/local/``. Which means that for ``/etc/ceph.conf`` the default location is ``/usr/local/etc/ceph/ceph.conf``. Smartest thing to do is to create a softlink from ``/etc/ceph`` to ``/usr/local/etc/ceph``:: ln -s /usr/local/etc/ceph /etc/ceph A sample file is provided in ``/usr/local/share/doc/ceph/sample.ceph.conf`` MON creation ------------ Monitors are created by following the manual creation steps on:: https://docs.ceph.com/en/latest/install/manual-freebsd-deployment/ OSD creation ------------ OSDs can be manually created only, see :ref:`freebsd_adding_osds`
