[ceph-users] virtual machines crashes after upgrade to octopus

* > Hello,* * >* * > Below is full debug log of 2 minutes before crash of virtual machine.* * Download from below url* * >* * > https://storage.habari.co.tz/index.php/s/31eCwZbOoRTMpcU <https://storage.habari.co.tz/index.php/s/31eCwZbOoRTMpcU>* * This log has rbd debug output, but not rados :(* * I guess you'll need to try and capture a coredump if you can't get a* * backtrace.* * I'd also suggest opening a tracker in case one of the rbd devs has any* * ideas on this, or has seen something similar. Without a backtrace or* * core it will be impossible to definitively identify the issue though.*
