Automatic merge from submit-queue (batch tested with PRs 42038, 42083) Add backup-volfile-servers to mount option. This feature ensures the `backup servers` in the trusted pool is contacted if there is a failure in the connected server. Mount option becomes: mount -t glusterfs -o log-level=ERROR,log-file=/var/lib/kubelet/plugins/kubernetes.io/glusterfs/glustermount/glusterpod-glusterfs.log,backup-volfile-servers=192.168.100.0:192.168.200.0:192.168.43.149 ..

Multipath
To leverage multiple paths for block storage, it is important to perform the
multipath configuration on the host.
If your distribution does not provide /etc/multipath.conf, then you can
either use the following minimalistic one:
defaults {
find_multipaths yes
user_friendly_names yes
}
or create a new one by running:
$ mpathconf --enable
Finally you'll need to ensure to start or reload and enable multipath:
$ systemctl enable multipathd.service
$ systemctl restart multipathd.service
Note: Any change to multipath.conf or enabling multipath can lead to
inaccessible block devices, because they'll be claimed by multipath and
exposed as a device in /dev/mapper/*.
Some additional informations about multipath can be found in the iSCSI documentation
