[ovirt-users] Troubles after resizing the iscsi storage.

[Arman Khalatyan]

Ok Thanks for the hints. After rebooting SPM host and re-importing the
storage the resize button is there, but the disks inside storage still
invisible. with lsblk I can see them but not over the ovirt.
The rescan disks and initiation of OVF_STORE update does not change the
situation. I can even new created disks, but the old disks are not visible.
