We are running Proxmox VE 3.0 on several nodes, installed on HW RAID10 arrays. General performance is fine, but there are particular containers that use extremely high IO. We could very much benefit from write-back SSD caching (bcache), but it looks like it's not going to happen anytime soon (soonest is after RHEL7 gets released).
According to the storage wiki:
OpenVZ containers must be on local storage or NFS
As these high IO containers are very latency sensitive, we should forget NFS storage, gigabit is simply not enough.
We are looking for a reliable way to add an SSD (as a locally mounted volume or directory) to an already installed Proxmox VE node to place 1-2 containers on it. Some kind of backup (not necessarily snapshot) should work on it, and preferably migrate as well.
Has anyone done this before successfully?
