    [SOLVED] Very poor IO Delay / FSYNCS/SECOND on RAID1 Sata disk

    Thanks for your help, I reinstalled old server with latest Proxmox version on ZFS instead of soft raid by OVH. Clearly, it's better, with no VM started, I hit 100+ FSYNCS/Second (not the best, but at least double old value). Next step, reinstall new server on ZFS and check if perf is better or...

    [SOLVED] Very poor IO Delay / FSYNCS/SECOND on RAID1 Sata disk

    Effectivelly, mdadm is default soft raid on OVH server, but, on your old server, we don't have this issue, so why this happen on new servers? For pveperf, I launched all the VMs on the old server and have ten times better performance, so, it's seem possible to improve perf, even on mdadm ?
