OSD crash, unable to restart

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have a small cluster(5 nodes, 20OSDs), where an OSD crashed. There is no any other signal of problems. No kernel message, so the disks seem to be OK.

I tried to restart the OSD but the process stops almost immediately with the same logs.

Version is 0.94.5 (9764da52395923e0b32908d83a9f7304401fee43) on an ubuntu 14.04 with kernel 3.13.0-68-generic.

See the logs from the relevant OSD below.
How can I fix this or what other info needed to find the issue?

Thanks,
Csaba
