I've successfully configured TrueNAS and Proxmox to work together using ZFS over iSCSI. However, creating, starting, destroying, or migrating a VM takes a LONG time. The logs for each event appear to be making retries. It always works, but the below entry shows up a few times before getting on with whatever task it's trying to do. Is this indicative of a problem or is there a way to speed this up?
My hosts are connected to storage via 10GB SFP+ DAC cables. Running hdparm, my read throughput doesn't seem to be significantly effected, though I would be interested to know what the bad/missing sense data is.
