Hi Dan,
Yes, I tried tweaking config following that link but for some reason the
sync progress is not showing any more.
I guess I need to fiddle with it more.
I have 16 x 500 GB disks in each server and my layout is as below:
1-4: VD0: RAID10: 2 spans of 2 disks -> 1TB for Proxmox containers and VMs
5-14: VD1: RAID50: 2 spans of 5 disks -> 4TB for storage (which I'm
trying to sync for redundancy using DRBD)
15-16: global hot spares
It appears to provide the best performance, resiliency and space
utilisation balance.
I've been referring to this chart:
https://www.datarecovery.net/articles/raid-level-comparison.aspx
Is there anything fundamentally wrong with my architecture?
Thanks,
Adam

Unrelated: how is it that you decided on RAID50 for 4TB of disk space?
If it's valuable, you should be looking at RAID10. If it's not
valuable, why 50 over 6 or RAIDZ2 or 3?
