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.

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.

Hi,
the appliance we publish actually does not enable the ISO domain on the VM anymore for exactly this reason. I believe we mention this in the documentation somewhere too.
Please do not put or disable all domains that are served from inside the engine VM.
Best regards

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:

This because the host has the iso domain nfs export mounted but the self hosted engine VM is not running, I think... So I have to reboot the host before change the maintenance mode.
