failed command: READ DMA EXT

I'm seeing these events in my log at least once per minute:

I think it's about my sli raid card, which has been fine for some time, but no longer. I'm attaching my diagnostics log. Is there something I can do here? Looks like there's going to be a problem w/ my drive connected to the raid card in the future, so any help here would be great. Thanks

I was getting the above error, though it was talking about my sata raid card. I attempted to clear it up by disabling iommu in syslinux.cfg, but the drives didn't show after a reboot. Same thing happened when I disabled the virtual settings in my bios. So, I disconnected the storage disks from the sata raid card, and connected them to the onboard sata connections. I also connected my cache drive to the sata raid card (as I'm out of sata ports on the mobo). I'm now getting Unmountable: Unsupported partition layout as the file system status on the cache drive, so that's not great. I don't mind wiping the cache drive if need be. Can anyone help w/ all this mess?

 

Thanks

Those SIL controllers are quite old and not recommended for some time, still it could be a cable/connection issue, try replacing the SATA cable, or swapping ports with one of the disks.

Can you recommend an inexpensive 4 port card, or point to someone who can?

I can't tell how up to date this is: https://wiki.unraid.net/Hardware_Compatibility#PCI_IDE_Controllers

Not many 4 port options, there's the old Adaptec 1430SA which still works fine (but not good for SSDs), and newer ones with 4 or 5 port based on the JMB585 chipset, these are rather recent but all indications so far is that they are reliable, though you can usually get a used 8 port LSI HBA for around the same price.

Thanks for the help. I'll be on the lookout.
