In ovirt 4.1 when I put the host into maintenance mode then the nfs mounts are unmounted as expected. but the hosts are still logged into the targets. The test disks are not attached to any virtual machine. nothing done on the hosts. I just saw that the all test LUNs are still logged into target side so I went to the host(it was in the maintenance ) all disks are still there. I just managing everything over the web gui: Select host as SPM, then disks->new->directLUN->discovertargets->login->ok on the host the disks are visible. iscsiadm -m session -o show tcp: [6] 10.10.10.35:3260,1 iqn.2003-01.org.linux-iscsi.c1701.x8664:sn.5b791971cd78 (non-flash) Putting host to maintenance: the disks are still there: lsscsi [0:0:0:0] disk ATA ST3500630NS K /dev/sda [11:0:0:0] disk LIO-ORG c1701iser 4.0 /dev/sdb [11:0:0:1] disk LIO-ORG c1701iser32k 4.0 /dev/sdc activating deactivating the host does not change situation. I dont see any attempt of vdsm to logout the disks. I can see in the vdsmd.logs that "[storage.Mount] unmounting /rhev/data-center/mnt/......" unmounting the nfs part but nothing from [storage.ISCSI]
This bug has not been marked as blocker for oVirt 4.3.0. Since we are releasing it tomorrow, January 29th, this bug has been re-targeted to 4.3.1.
We didn't get to this bug for more than 2 years, and it's not being considered for the upcoming 4.4. It's unlikely that it will ever be addressed so I'm suggesting to close it. If you feel this needs to be addressed and want to work on it please remove cond nack and target accordingly.
Closing old bug. Please reopen if still relevant/you want to work on it.
