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::
|
|
|
|
http://docs.ceph.com/docs/master/install/manual-deployment/
|
|
|
|
|
|
OSD creation
|
|
------------
|
|
|
|
OSDs can be create with ``ceph-disk``::
|
|
|
|
ceph-disk prepare /var/lib/ceph/osd/osd1
|
|
ceph-disk activate /var/lib/ceph/osd/osd1
|
|
|
|
And things should automagically work out.
