January 11, 20233 yr This might be a whole thing, but I have been dealing with quite a few CRC errors on my disks. I have changed the cables power supply and even the case to do away with the back plane and connected my SAS to SATA card directly to the drives. Recently I have been rearranging my shares which means I have been moving a lot of data within the array. Several times during this process the webgui becomes unresponsive and slowly over the course of several hours I start losing docker containers and the ability to connect using SSH. Before I lose the ability to connect via SSH, powerdown doesn’t work and downloading the diagnostics just hangs up. Eventually I must force an ungraceful shutdown. Fortunately, or unfortunately, this hasn’t happened since I started keeping persistent logs. So I don’t have any from when that happened and I am not sure if this is related to the disk issues or not. I have noticed several disk errors on one particular drive located at ata14.00. Last night that drive disconnected from the array and I was only able to get unraid to recognize it again once I unplugged it and plugged it back in so it could have been a loose connection. During this time I rearranged several of the sata connectors and I am still getting the same errors this time on ata15.00 so I assume it is drive related. My array consists of mostly WD red 4 and 8 tb drives but the vast majority of errors are isolated to three 8tb white label EDAZ drives that I shucked from easystore or element enclosures. Its hard for me to imagine that all 3 of these drives are bad but that seems to be the common dominator so any input would be appreciated. I have attached the server logs that I have as well as the SMART data from the 3 drives. Any input would be appreciated.

January 11, 20233 yr Community Expert FYI, diagnostics already includes those other files you attached. Always better to just give us that.
January 11, 20233 yr Community Expert Marvell controllers are NOT recommended. It has been reported that some people have had better luck with them by disabling IOMMU (AMD-Vi) in BIOS. Not sure it that is still the current advice.

Yeah I didn't originally include the diagnostic because the log file wouldn't have gone beyond my last reboot. 1 hour ago, trurl said: Marvell controllers are NOT recommended.

Ah, I have been debating whether I should look into getting a LSI card in it mode. I'll try disabling IOMMU to see if that helps.

Not sure it that is still the current advice. One other question. If I disable IOMMU will I still be able to pass my z-wave usb dongle through to my home assistant vm?
