ZFS Faulted Device - new SSDs

Hi All,

I've been wrestling with this problem for a while. I keep getting a degraded ZFS pool due to 'too many write' errors. The pool is a Raid 0 set of two SSDs that is dedicated to my Containers and VMs.

I've recently swapped the SSDs for Samsung PM893s and also replaced the SATA cables. Still with the same results.

Here's my current configuration:
  • Supermicro H11SSL-i with 64GB of memory
  • Epyc Processor: AMD EPYC 7551P 32-Core Processor
  • Latest BIOS
  • Two 100GB SSDs in Raid 1 Zpool for the boot and OS connected directly to SATA ports on MB
  • Two 480GB SSDs in Raid 1 Zpool for the KVM/LXC connected directly to SATA ports on MB
  • One 500GB HDD for DVR on Plex LXC connected directly to SATA ports on MB
  • One 500GB HDD for Proxmox KVM and LXC backup connected directly to SATA ports on MB
  • Three HDDs in PCI Passthrough to TrueNAS VM for NAS services connected directly to SATA ports on MB
Could this be case of the issue being with the SATA "controller"? I believe that there isn't a controller on the MB, and that the EPYC has a "built-in" interface.

Before I drop ~$150 on an LSI 9300 HBA card, are there any other configurations I could try? I suppose I could move away from ZFS, but I don't know enough about advantages/disadvantages of various Linux FS and Proxmox to make the right decision.

FYI, this is a home-lab system. Although it's not a "mission critical" system, if it goes down I start catching hell from the wife and kids.

Thanks in advance.

Are you passing just the disks or the sata controller through to the TrueNAS VM? Could be where your problem is perhaps?

Also, why a raid0?
1.) you really mean a raid0 (ZFS stripe) and I don't see the point doing that...
2.) you actually mean a raid1 (ZFS mirror)
3.) you are using pseudo HW raid1 of your mainboard and then use "single disk" (=raid array) ZFS raid0 because it is alread mirrored

In my opinion, 1 and 3 would be a bad choice.

Apologies. I meant raid1 (ZFS mirror).
 
There are groups of SATA ports that show up as different PCI controllers. I am only passing through the group shown by the green rectangle below. The LSI3008 doesn't exist on my version of the MB.

Here is the log output from the last time there was a fault:

Entschuldigung das ich in deutsch schreibe. Mein Englisch ist schlecht.
Ich habe das gleiche Board, Supermicro-H11SSL-I und die gleichen Probleme wie Du. Geräte die an SATA 8-11 und SATA12-15 hängen, bei mir EXOS X16 über Backplane, fallen mit ZFS Lese oder Schreibfehlern aus. An SATA 0-7 ist alles ok (bei mir SSD). Ich habe nun testweise Smart bei den HDDs wie in https://forum.proxmox.com/threads/zfs-fault-imme-wieder-bei-einem-system.81860/ deaktiviert und teste.

Viele Grüße
