OpenStack Block Storage (Cinder)
7cc2e402f9
Any method in the remotefs/nfs code that manipulates the qcow2 snapshot chain must be run separately from other methods that may touch this snapshot chain. This code intended to do this with a lock on the volume id, but it unintentionally locked only on the destination volume id rather than the source volume id where the snapshots are. This causes concurrent clone operations to fail in the NFS driver. This patch fixes this in the RemoteFSSnapDriverDistributed class which fixes the NFS driver and a handful of others. A follow up patch should be applied for the RemoteFSSnapDriver class with a similar change, but as that class is only used by one driver (which I can't test), this patch only adds a TODO for that change.
