Re: [ovirt-users] Consolidating LUNs in iSCSI storage domain

From the doc:

Hi and thanks for the response Is there any way that this could be done without putting the entire datacenter (and I assume shutting done all the VMs) into maintenance mode? I was thinking along the lines of: - Put all hosts except for the the SPM into maintenance mode - Determine which LUNs match to the "/dev/dm-*" devices that the three I want to remove (rhev-data01, rhev-data02, rhev-data03) - Determine which LUN matches the "/dev/dm-*" devices that I want to keep ( rhev-data04) - pvmove rhev-data01 rhev-data04 - pvmove rhev-data02 rhev-data04 - pvmove rhev-data03 rhev-data04 The pvmove commands above for illustration only, I know thats not how the LUNs would be called. Does that look like it would work?
