Ian, knara,
<br>
<br>success! I got it working using the two-dash-notation and ip addresses. Shure this is the most relyable way, even with local hosts file.
<br>
<br>In my case, the hosted vm dies and takes some time to be running again. Is it possible to have the vm surviving the switch to the backup-volfile-server?
<br>
<br>Thanks & regards

Looks like your conf is incorrect for mnt option.

Hi Ian,

mnt_option should
be
mnt_options=backup-volfile-<wbr>servers=<IP1>:<IP2> and
this
is how we test it.

thank you. I tested and it seems not to work,
even
after rebooting the current mount does not show up
the
mnt_options nor the switch over
works.

<pre>Hi,
how do i make the hosted_storage aware of gluster server failure? In --deploy i
cannot
provide backup-volfile-servers. In
/etc/ovirt-hosted-engine/hoste<wbr>d-engine.conf
there
is
an mnt_options line, but i
read

that this settings get lost during deployment on seconday
servers.
Is there an official way to deal with that? Should this option be set manualy on
all
nodes?
Thanks!

Hi,

I think in the above patch they are just hiding the the
query
for mount_options but i think all the code is still present and
you
should not loose mount options during additional host
deployment.
For more info you can refer [1].

You can set this option manually on all nodes by
editing
/etc/ovirt-hosted-engine/hoste<wbr>d-engine.conf. Following steps
will
help you to achieve
this.
