Hello,
I am experiencing an issue where OSD Services fail due to an unexpected aio error. This has happend on two different OSD servers killing two different OSD Daemons services.
I am running Ceph Hammer on Debian Wheezy with a backported Kernel(3.16.0-0.bpo.4-amd64).
Below is the log from one of the crashes.
I am wondering if anyone else has experienced this issue and might be able to point out some troubleshooting steps? so far all i’ve found are similar issues on the ceph bug tracker. I have posted my case to that as well.
