Description Christian Bricart 2012-07-04 18:01:13 UTC

ceph.com released version 0.48 which is also announced to be "LTS".
(both current portage main tree and gpo.zugaina.org list 0.41 and ~0.44 as latest ebuilds)
bug #410003 lists build problems with 0.44 from the tree and mentioned a bump 0.47 to a local overlay
so bumping to upstream LTS might be a good idea after all

Reproducible: Always




looking at upstream's release notes, the package may not simply be bumped.
Quote:
* You will not be able to downgrade from v0.48 to a previous version.
* Each ceph-osd will need some time to convert its local data before rejoining the cluster.  If you need to maintain availability, you will need to do a “rolling upgrade” by restarting daemons on each host or rack in sequence and allowing the cluster to recover before moving on to the next one.  Note that for non-btrfs file systems especially this can be slow (many hours); plan accordingly.
* The ceph tool’s -s and -w commands from previous version are incompatible with this version.  Upgrade your client tools with your monitor if you rely on those commands.

That might be worth adding a upgrade blocker and prepare a news item...
