GlusterFS as virtual machine storage
...maintenance.
However we are still on native client as we haven't had time to work on
libgfapi yet. Maybe that is more tolerant.
We have linux VMs mostly with XFS filesystems.
During the downtime, the VMs continue to run with normal speed.
In this case we migrated to the VM so date node 2 (c2g.gluster) and
shutdown c1g.gluster to do some upgrades.

We use whatever official cloud (Openstack) images provide, all tests I
describe are on Ubuntu Xenial VMs, ext4.

So, seems to be reliable to server crashes but not to server shutdown :)

GlusterFS as virtual machine storage
Gandalf, SIGKILL (killall -9 glusterfsd) did not stop I/O after few
minutes. SIGTERM on the other hand causes crash, but this time it is
not read-only remount, but around 10 IOPS tops and 2 IOPS on average.
