Upgrading
|
|
---------
|
|
|
|
* Ceph daemons now run as user and group ceph by default. The ceph user has a
|
|
static UID assigned by Fedora and Debian (also used by derivative distributions
|
|
like RHEL/CentOS and Ubuntu). On SUSE the ceph user will currently get a
|
|
dynamically assigned UID when the user is created.
|
|
|
|
If your systems already have a ceph user, upgrading the package will cause
|
|
problems. We suggest you first remove or rename the existing 'ceph' user
|
|
before upgrading.
|
|
|
|
When upgrading, administrators have two options:
|
|
|
|
#. Add the following line to ``ceph.conf`` on all hosts::
|
|
|
|
setuser match path = /var/lib/ceph/$type/$cluster-$id
|
|
|
|
This will make the Ceph daemons run as root (i.e., not drop
|
|
privileges and switch to user ceph) if the daemon's data
|
|
directory is still owned by root. Newly deployed daemons will
|
|
be created with data owned by user ceph and will run with
|
|
reduced privileges, but upgraded daemons will continue to run as
|
|
root.
|
|
|
|
#. Fix the data ownership during the upgrade. This is the preferred option,
|
|
but is more work. The process for each host would be to:
|
|
|
|
#. Upgrade the ceph package. This creates the ceph user and group.
|
|
#. Stop the daemon(s)
|
|
#. Fix the ownership. E.g.,::
|
|
|
|
chown -R ceph:ceph /var/lib/ceph/mon/ceph-foo
|
|
ceph-disk chown /dev/sdb1
|
|
|
|
#. Restart the daemon(s)
|
|
|
|
* The on-disk format for the experimental KeyValueStore OSD backend has
|
|
changed. You will need to remove any OSDs using that backend before you
|
|
upgrade any test clusters that use it.
