Re: [Users] online storage domain resize
Hi If you want to enlarge an existing storage domain the easiest way is to extend the storage domain. You can edit the domain and add another LUN to be a part of that domain and oVirt will take care of extending the domain - the only thing you need is another LUN to use. wow, it it looks so simple that I didn't even realize that it could work :-) You are right, I can select another non used LUN to expand storage domain. I'll try it tomorrow Thanks Jiri Thanks, Gadi Ickowicz - Original Message - From: Jiří Sléžka jiri.sle...@slu.cz To: users@ovirt.org Sent: Monday, January 20, 2014 4:57:34 PM Subject: [Users] online storage domain resize 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: pvcreate to create a new PV on the available space vgextend to add the new pv to the existing vg enjoy additional space. Others will have to chime in on whether oVirt breaks this process somehow (I am using gluster for my storage), but I doubt it.
