Hello,
I'm just curious and I didn't try it already. I'm using FC storage (Dell MD3620f) with some logical disks on it. I should be able online increase virtual disk capacity using storage management (I have some free capacity on disk group).
Is there any way to on-line extend volume group used for vm's images storage and don't break anything?
I just found this hint by Eduardo from list
1. Shutdown all VMs 2. Manually connect iscsi on the SPM host 3. Run pvresize on the LUN 4. Put the domain in maintenance 5. Activate the domains
Is it possible to do this on-line without shutting down all vms? If not, it could be really nice feature for oncoming releases.
Thanks in advance
Jiri I don't know if oVirt is "breaking the rules" for using LVM, but in regular Linux all you have to do is:

Others will have to chime in on whether oVirt breaks this process somehow (I am using gluster for my storage), but I doubt it. Ted Miller Elkhart, IN, USA
