Subject: Is Ceph recovery able to handle massive crash
Date: Sat, 05 Jan 2013 13:19:09 +0100	[thread overview]
Message-ID: <50E81A3D.5070100@ledeuns.net> (raw)

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 ?

Regards,
Denis
