Based on my Gluster setup,

I have noticed that setting the storage domain into maintenance , just umounts the storage on all hosts.

It also doesn't stop the gluster volume , so I do not expect the same for the iSCSI.

I guess you can set it to maintenance and then manually logout the 2 hosts.

Then , when you start it - it should login and mount the storage.

Best Regards,

Hello,

I have a cluster composed by two hosts connected to some iSCSI storage domains.

I have put one host into maintenance and I see that all the iSCSI sessions are closed. So far so good.

Then I put one storage domain into maintenance and I would expect to see on the active host the (2) iSCSI sessions versus this storage domain to get closed.

Instead I continue to see them up and "multipath -l" command gives me the 2 paths for the LUN part of the storage domain connection.
Is this expected and only when I execute detach of the SD I will get the closure of the iSCSI connections?
Because the detach phase will unregister the VMs and I would like not to do it, but at the same time I will have a planned maintenance for this storage domain and I would like to clean the connections on host side, to let multipath happy when they will go down for some hours...

Thanks in advance for any insight.

Gianluca
