[ovirt-users] Storage, extend or new lun ?

[Fred Rolland]

Hi,

You can manually do the resize (Steps here are for FC) :
- Move the Storage Domain to maintenance
- First locate the LUN ID you want to refresh with :multipath -ll
On each hosts:
 - Run : rescan-scsi-bus.sh
 - Run: multipathd resize map 3600a0b800075de8f00000e3a52ddf25f   (replace
with your LUN_ID)
 - Check that the size was updated in multipat -ll
On the SPM:
 - Run: pvresize  /dev/mapper/3600a0b800075de8f00000e3a52ddf25f
 - Check with vgs

Move the domain to active again.
I am not sure that the engine will see the new size immediately. An engine
restart might be needed.

Regards,

Fred
