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] On Thu, Feb 16, 2017 at 4:25 PM, Nir Soffer <nsof...@redhat.com> wrote: > On Thu, Feb 16, 2017 at 5:13 PM, Arman Khalatyan <arm2...@gmail.com> > wrote: > > Hi, > > 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. > > > > Is it expected behavior??
