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?
Thanks

Hi,
oVirt allows such operations using this feature [1]. Basically, while the storage domain is deactivated (maintenance status), you'll have to replicate all the data to the fourth LUN (from the storage server side), replace the storage connections of this storage domain from RHEVM REST API (explained in [1]) and to activate the domain.

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
