At the same time, i notice a hanging /etc/libvirt/qemu gfs2 mount (
while /var/lib/libvirt/sanlock still works fine ) on vm02. vm01 and vm03
have perfectly accessible mounts. Nothing special to see in syslog or
dmesg..
/dev/mapper/iscsi_cluster_qemu on /etc/libvirt/qemu type gfs2
(rw,relatime,hostdata=jid=2)
/dev/mapper/iscsi_cluster_sanlock on /var/lib/libvirt/sanlock type gfs2
(rw,relatime,hostdata=jid=2)
Any ideas?

Hello again ;)
My cluster seems to be logging only to /var/log/syslog, and even then
only from the corosync daemon, the /var/log/cluster logs are empty:
root@vm01-test:~# ls -al /var/log/cluster/*.log
-rw------- 1 root root 0 Aug 16 06:50 /var/log/cluster/corosync.log
-rw------- 1 root root 0 Aug 20 06:39
/var/log/cluster/dlm_controld.log
-rw------- 1 root root 0 Aug 20 06:39 /var/log/cluster/fenced.log
-rw------- 1 root root 0 Aug 7 06:27 /var/log/cluster/fence_na.log
-rw------- 1 root root 0 Aug 16 06:50
/var/log/cluster/gfs_controld.log
-rw------- 1 root root 0 Aug 20 06:39 /var/log/cluster/qdiskd.log
-rw------- 1 root root 0 Aug 20 06:39 /var/log/cluster/rgmanager.log
Also, I've shut down my 2 vms with virt-manager or with halt from the
cli on the guest itself.
virsh list on all 3 nodes show no running guests. However:

I hope you guys can shed some light on this.. CMAN, rgmanager, ... =
3.1.7-0ubuntu2.1, corosync = 1.4.2-2
Kind regards,
