Hello,
The names of pgs start with "7.". so they are used by the pool id 7 ?
For me, it's cephfs_meta ( cephfs metadata ). I get no response when i
done "rados -p cephfs_meta ls" .
Like it's a small share, it's not serious. I can restore it easily. So I
add the news OSDs of the new machine.
And it solved the problem, but i don't understand why. So if someone
have an idea ?
Regards
PS : I use 0.80.10 on wheezy
