Yes, removing a lun from a storage domain require moving the storage
domain to maintenance.

If there is no space to remove a lun, you will not be able to remove it even
if the domain is in maintenance.

OK.

Am I right about the following: A storage domain needs to be in 
maintenance mode before a LUN may be removed from it?

- And if so: This means that ovirt does not support online removal of a 
LUN from a storage domain, even if there's sufficient free space in other 
LUNs in the storage domain?

Hi,

You cannot put a storage domain to maintenance if you have running VMs
using disks located in this domain.
Putting a storage domain to maintenance will disconnect all hosts from the
storage backend (NFS :unmount, ISCSI: iscsiadm -m session -r )-u)

Freddy
