[ovirt-users] Re: HE LUN change

Thanks for the hint Simone, I may try the shortcut. Alternatively would it be possible to use LVM tools VGExtent - PVMove and then remove to old LUN? Do you see any problem when using LVM? This could even be done on a running system... regards, Arsene On Fri, 2018-05-18 at 09:23 +0200, Simone Tiraboschi wrote: Hi, the proper way is trough backup/restore following https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Resto... If you want to try a shortcut, I'm pretty confident that if both the source FC LUN and the target one are correctly mapped on the relevant hosts, you could simply: - set global maintenance mode - shutdown the engine VM - stop ovirt-ha-agent and ovirt-ha-broker on all the involved hosts - copy the source LUN content over the target LUN with dd - filter out the source LUN at multipath level - restart the relevant services On Wed, May 16, 2018 at 3:31 PM, Arsène Gschwind <arsene.gschwind@unibas.ch<mailto:arsene.gschwind@unibas.ch>> wrote: Hi, We are running HE on a separate FC LUN on a storage system which needs to be replaced, what would be the best method to move / copy that LUN to another FC LUN?
