Hi
I was testing yesterday the intermediate truenas server between 2 nodes, since they now both have it as a remote storage. On truenas side, I used as a backup pool a set of 6 disks (sas3 hdd 2.5" 1.2tb /10k each) and set them as raidz2. On proxmox all vm's are on a raid 10 (striped mirrors - ok zfs doesn t have a direct raid 10 as many explain)
consisting of 4 drives. The connection between proxmox - truenas is a 10gbe direct connection, using that subnet only for backups and nothing else. Finally the share from truenas is exposed to both servers as NFS.
So what I noticed while I was doing a VM backup having selected the remote storage as a destination was low speeds that I can t explain. See pic attached below
When restoring the backup from truenas to proxmox again (second node with 4k zvol pool instead of the 8k of the previous server from which backup is taken at first place, but again with 10gbe connection I m having below warnings
and after completion
I believe above messages are normal taking into consideration the difference of the zvols between two servers right?
