Sizing the master storage domain
by Nicolas Ecarnot 19 Nov '14

19 Nov '14

Hi, I know Itamar explained that the notion of master storage domain will disappear in some releases. But now, with a 3.4 I'm installing, I was wondering : - on my other oVirt setups, I started with one big (iSCSI) LUN, which is the master, and stored as many VMs I could - when space came to miss, I added another LUN, the another... - when I have to do some maintenance (grow, disable, other...) on a LUN, I can move my VM disks amongst the normal storage domains. When Empty, I can switch them off, add others, and so on The only one I can not play with is the master one. I came to think that I had no benefice storing anything on the master storage domain, and use only the normal storage domains. And then, I came to think I had no reason to dedicate a huge LUN for the master. Ok, but according to you, what is the minimum reasonable size for a master storage domain? -- Nicolas Ecarnot

Gluster access tied to one node?
by Chris Adams 19 Nov '14

19 Nov '14

So this may be a dumb question, but here goes... I set up a replicated Gluster volume for VM disk image storage. I specified the path as node9:gluster1 (where node9 is one of the two nodes with a brick). However, when I shut down node9, the VM using that storage automatically gets paused. I thought the replicated storage was supposed to work even if one node was down. Is there some other way to specify the path (did I do that wrong)? -- Chris Adams <cma(a)cmadams.net>

Complete evalution of backup solutions
by Mario Giammarco 19 Nov '14

19 Nov '14

Hello, I am evaluating ovirt and considering backups. I have three solutions: 1) iscsi san that does snapshots 2) Glusterfs 3) ovirt api So I have these questions: - if I use 1) can I import a snapshot as different storage domain? - glusterfs snapshot implementation is ready? Can I do consistent backups of gluster bricks? - is there an opensource backup software that can do incremental backups using ovirt api? Thanks in advance for interest, Mario

Have somebody any idea how to do it? -- G.Sz.

Engine: Get guest XML dump
by Daniel Helgenberger 19 Nov '14

19 Nov '14

Hello, after working with Foreman for a while come to love the yaml dump feature for hosts as it proved invaluable for debugging and setups [1]. After some questions on the list here if for instance libgfapi is being used I think such a feature also might prove useful in oVirt. Right now, I log into the host running the vm and to this with virsh dumpxml. I imagine something like -> right click on a guest and choose 'XML dump'; or a XML tap in the VM edit window. If somebody else thinks this is useful too, I will open a RFE. Cheers, [1] https://www.youtube.com/watch?v=Ksr0tilbmcc#t=78 -- Daniel Helgenberger m box bewegtbild GmbH P: +49/30/2408781-22 F: +49/30/2408781-10 ACKERSTR. 19 D-10115 BERLIN www.m-box.de www.monkeymen.tv Geschäftsführer: Martin Retschitzegger / Michaela Göllner Handeslregister: Amtsgericht Charlottenburg / HRB 112767
