Hi guys, I was wondering if this is a bug?
I've noticed that during volume migration from NFS to RBD primary storage the volume image is first copied to /tmp and only then to the RBD storage. This seems silly to me as one would expect a typical volume to be larger than the host's hard disk. Also, it is a common practice to use tmpfs as /tmp for performance reasons. Thus, a typical host server will have far smaller /tmp folder than the size of an average volume. As a result, volume migration would break after filling the /tmp and could probably cause a bunch of issue for the KVM host itself as well as any vms running on the server. It also seems that the /tmp is temporarily used during a template creation . My setup: ACS 4.2.1 Ubuntu 12.04 with KVM RBD + NFS for Primary storage NFS for Staging and Secondary storage Thanks Andrei
