Hello all,
I'm using Ceph 0.55.1 on a Debian Wheezy (1 mon, 1 mds et 3 osd over
btrfs) and every once in a while, an OSD process crashes (almost never
the same osd crashes).
This time I had 2 osd crash in a row and so I only had one replicate. I
could bring the 2 crashed osd up and it started to recover.
Unfortunately, the "source" osd crashed while recovering and now I have
a some lost PGs.
If I happen to bring the primary OSD up again, can I imagine the lost PG
will be recovered too ?
Ok, so it seems I can't bring back to life my primary OSD :-(

When I "rbd list", I can see all my images.
When I do "rbd map", I can map only a few of them and when I mount the
devices, none can mount (the mount process hangs and I cannot even ^C
the process).
Is there something I can try ?
Thank you in advance,
Denis
