Hi Nir,
Here is another one, this time with strace of children and gdb dump.
Interestingly, this time, the qemu seems stuck 0%, vs 100% for other cases.
The files for strace are attached.
Hopefully Kevin can take a look.
The gdb + core dump is found here (too
big):
https://dl.dropboxusercontent.com/u/63261/gdb-core.tar.gz
I think it will be more useful to extract a traceback of all threads
and send the tiny traceback.
gdb --pid <qemu pid> --batch --eval-command='thread apply all bt'
If it helps, most machines get stuck on the host hosting the
self-hosted
engine, which runs a local 1-node glusterfs.
And getting also /var/log/messages, sanlock, vdsm, glusterfs and
libvirt logs for this timeframe
would be helpful.
Nir
Thank you for your help,
