Hi!
A few days ago I added a bunch of new OSDs to hour production servers, we
have 3 hosts that maps and unmaps hundreds of RBD devices every day. with
aprox 100 RBD devs mapped at each host at any given time.
Adding OSDs is usually quite smooth if you do it the right way. I usually
follow the Manual adding/remove of osd as explained in the documentation.
Except when it comes to the crush add, i prefer decompiling and compiling
my own crush map.
So I preceded as usuall, prepared the OSD disks, keyring and so on, and
then I started up 4 new ceph-osd (osd.{9,10,11,12}) on the new OSD host.
BAM; a host that had a bunch of RBD devs mapped crashed and rebooted with
this in the log: http://pastebin.com/YKJSdWLv
I realise that this is not much to go on since there's no stack trace or
anything, but if anyone can help me reproduce this, I'd be grateful. And if
anyone had the same issue would really like to hear from them too.
I'm running Linux 3.14.1 and ceph 0.72.2.
Thank you for your time,
Thorwald Lundqvist.
