Hello,
Besides the performance inconsistency (see other thread titled poor OSD
performance using kernel 3.4) where I promised some tests (will run this
afternoon), we tried this week-end to stress test ceph, making backups
with bacula on a rbd volume of 15T (8 osd nodes, using 8 physical machin

a long time.
I can't send those logs anymore, they are rotated now...
Anyway. Now tha

Tried to restart osd with 0.47.3, then next branch, and today with 0.48.
