[ovirt-users] Managed Block Storage issues

Hi all, I am trying to set up Managed block storage and have the following issues. My setup: Latest oVirt Node NG : 4.4.8 Latest oVirt Engine : 4.4.8 1. Unable to copy to iSCSI based block storage I created a MBS with Synology UC3200 as a backend ( supported by Cinderlib ). It was created fine but when I try to copy disks to it, it fails. Upon looking at the logs from SPM, I found "qemu-img" failed with an error that it cannot open "/dev/mapper/xxxxxxxxxx" : Permission Error. Had a look through the code and digging out more, I saw that a. Sometimes /dev/mapper/xxxx symlink isn't created ( log attached ) b. The ownership to /dev/mapper/xxxxxx and /dev/dm-xx for the new device always stays at root:root I added a udev rule ACTION=="add|change", ENV{DM_UUID}=="mpath-*", GROUP="qemu", OWNER="vdsm", MODE="0660" and the disk copied correctly when /dev/mapper/xxxxx got created. 2. Copy progress finishes in UI very early than the actual qemu-img process. The UI shows the Copy process is completed successfully but it's actually still copying the image. This happens both for ceph and iscsi based mbs. Is there any known workaround to get iSCSI MBS working? Kind regards, Shantur
