Hi,
I've a libvirt-VM that gets format 2 rbd-childs 'fed' by the superhost.
It crashed recently with this in the logs:
osdc/ObjectCacher.cc: In function 'void
ObjectCacher::bh_write_commit(int64_t, sobject_t, loff_t, uint64_t,
tid_t, int)' thread 7f0cab5fd700 time 2013-03-01 22:02:37.374410

If some dentries were pruned or FILE_SHARED cap was revoked while
readdir is in progress. make sure ceph_readdir() does not mark the
directory as complete.

dentry_lru_prune() should always call file system's d_prune callback.

What's the cluster look like? This is just one active MDS and a couple

Hi,
We did the opposite here; adding some SSD in free slots after having a
normal cluster running with SATA.
Thanks for your answer. Why did you do this? Was it to slow with SATA?

Well, you'll need to learn how to use git at a basic level in order to be able
to work effectively on Ceph (or most other open-source projects).

I'm pulling this in for now to make sure this clears out that ENOENT bug we hit
— but shouldn't we be fixing ceph_i_clear() to always bump the i_release_count?
It doesn't seem like it would ever be correct without it, and these are the
only two callers.
The second one looks good to us and

Hi Yehuda,
I'm not sure if one keystone for all zones would be better than one keystone
per zone. If you think it's worth discussing during the OpenStack summit and
you create a session http://summit.openstack.org/cfp/create in the keystone
track, I will definitely attend :-). Or I can do it
