Re: [ovirt-users] Leaving maintenace mode
Hi,
we will focus on this exact issue (and couple of similar ones) in the
next release, but the reason is actually pretty simple.. the ISO
domain is mounted to the /rhev space and a when a simple traversal
hits the unavailable NFS ISO domain, it gets stuck.. and the timeout
is somewhat long.

Re: [ovirt-users] Leaving maintenace mode
Hi!
You are right! But I think isn't correct that the command fail if the
iso domain isn't available.
I'ts ok if the comman fail when the self hosted engine storage is not
available, but not for iso domain.

[ovirt-users] Leaving maintenace mode
Hi!
I have a testing oVirt installation with only one host and running self
hosted engine.
If I put host in global maintenance mode:
hosted-engine --set-maintenance --mode=global
then ssh into self hosted engine VM, shoutdown VM using 'init 0', when
I run on the host:
hosted-engine --set-maintenance --mode=none
I have:
