Proxmox with Ceph - How to implement VM disk storage quotas per user?

[victorhooi]

Is there some way of implementing storage quotas per user, if you're using Ceph RBD for VM disk storage?

For example, limit users in group A to a maximum of 1TB, or limit group A as an aggregate to 1TB etc?

This could be done through namespaces. But see the link below.

Hi,

Oh great - this namespace feature looks really neat.

I saw in the thread you linked that it was pending QEMU 5.0.

However, I am running pve-test, and QEMU 5.0 now seems to be released there.

Does that mean RBD quotas should work now?

Is there some Proxmox Web UI integration that needs to happen as well?

Also - in terms of setting quotas - there is documentation for setting quotas per pool here:

https://docs.ceph.com/docs/jewel/rados/operations/pools/#set-pool-quotas

However, do you happen to know how that command work for namespaced pools?

Thanks,
Victor
