Networking and servers • Pi5 OMV SSD RAID5 NAS degraded drive when moving data

Hi

I am currently playing with a set up to create a Pi5 based NAS with RAID 5 on the Open Media Vault platform. I'm currently testing with 4 cheap and small SSDs with the view to go big when I'm happy.

Kit list is:
Pi5 8GB
Geekworm X1011
4 x SK Hynix BC501 128GB
5v 50w PSU

Versions:
7.4.10-1 (Sandworm)
Raspberry Pi 5 Model B Rev 1.0
Linux 6.6.51+rpt-rpi-2712

Everything is working 100% fine and I'm very happy with it until.... Until I move a large amount of data to the drive. When I do this one of the drives will, at some point, stop reporting S.M.A.R.T. data to OMV and after the transfer is complete the Multiple Device section in OMV will report a degraded drive. On checking the disks in OMV the disk that stopped reporting data is "missing".

If I then reboot the system the drive reappears and if I then reboot for a second time everything is fine, the disk is back and the Multiple Device section reports a "clean" drive.

Any thoughts?
