[ovirt-users] Leaving maintenace mode

[Martin Sivak]

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.
