Hi all In one of our RHEV setups (v3.5.4) the iSCSI storage domain consists of four LUNs. (full details in the attached text file). I want to consolidate all the data on LUNs iqn.2003-10.com.lefthandnetworks:iscsi:341:rhev-data01 qn.2003-10.com.lefthandnetworks:iscsi:453:rhev-data02 iqn.2003-10.com.lefthandnetworks:iscsi:518:rhev-data03 to LUN iqn.2003-10.com.lefthandnetworks:iscsi:687:rhev-data04 Is this possible? Thanks CC _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users

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?

Hmm, OK. Are there plans to eventually support what I'm looking for?
