distribute storage domains
Hello I'm trying to figure out a way to automatically distribute our storage domain occupation evenly or at least avoid them getting full. We have a lot of users creating vms and they seem to select the first available storage domain, thus one is nearly full and the rest are barely used. Is there a way to accomplish that? Thank you Jason
Hi Jason, From a user experience perspective, you could change the order of the storage domains so the current first one is not always the first one in line. This might help to get users to select a variety of storage domains instead of always selecting the current first one. Best, Laura On Tue, Aug 6, 2019 at 7:05 AM Jason M.

Hi Laura, this is something I was wondering for quite some time but never bothered to ask about. How can one change the order of storage domains so the right one shows up by default?

Hi Dmitry, You might have to write a custom script for it but if you think other users would benefit from it you should totally contribute it! Best, Laura On Tue, Aug 6, 2019 at 10:54 PM Dmitry Filonov <filonov@hkl.hms.harvard.edu> wrote:

Hi Jason, A time ago I wrote a "Storage Balancer" exactly for that, move disks between storage domains to keep them below a maximum threshold of occupation. You can find the project at [1]. It's not perfect but has been working for us for the last 3 years with no issues. That won't avoid people storing new disks in the first available storage domain, but the balancer will distribute them between the less occupied storage domains afterwards. Hope this helps, Nicolás [1]: https://github.com/nkovacne/ovirt-storage-balancer El 2019-08-04 17:57, Jason M. Stallings escribió:

Nicolas: Thank you very much for this! Looks like exactly what I was looking for... The first burst was somewhat frightening but it ended well and now no storage domain is overused :) One quick question: Is it possible to limit balancing to more than one datacenter? I have 3 datacenters and I'd like to exclude one of them. I see the DATACENTER config variable could do this but I'm not sure how to define more than one datacenter.

Glad to hear that!

Currently, the DATACENTER parameter only allows one value. When developing the code I didn't expect someone having more than two Data Centers :-) As a workaround, if you want to exclude the Storage Domains of an entire Data Center, you can exclude them explicitly using the "NOBALANCE" parameter of the config file, which does allow several values. If you consider this is something that should be implemented, feel free to fill an issue or extend the code and send a Pull Request. Regards.
Thanks

Ok, that works. I have few storage domains so no problem adding them to the list. Thanks!!

It's ok that way, no need to change it as far as I'm concerned Thank you
Regards.
Thanks
