March 9, 20206 yr Hi there. A few days ago, I saw the docker service (docker image and appdata on cache) crash and got a warning that both of my parity disks entered error state and in the Main page show up as "Parity device is disabled", and was unable to restart docker from Settings. I rebooted the server and my dockers were back. I stopped the array, unassigned the parity disks, started the array, stopped the array, and reassigned the parity and started again, starting a parity rebuild. The same thing happened today with the docker service crashing, and the parity disks entered error state during the rebuild. Attached diagnostics from the recent crash. Not too sure what's at fault here, any help is appreciated!

March 9, 20206 yr I think you must have some sort of controller problem, or possibly power. Your diagnostics don't even give consistent information about whether your disks are mounted or not. df shows only cache, vars shows all mounted. And shares says none exist, as does df. Disabled parities of course should have no effect on your data whether on disks in the array or in the cache pool. Nothing obvious in syslog beyond possible corruption of libvirt and docker images. And some problems writing parity and reading cache. Reboot and post another diagnostic. Those don't make any sense.
March 9, 20206 yr There was a problem with the onboard SATA controller: Mar 9 01:41:23 MXCR-Unraid kernel: ahci 0000:03:00.1: Event logged [IO_PAGE_FAULT domain=0x0000 address=0x00000000e394c000 flags=0x0000] I've seen this multiple times on this forum with Ryzen boards, it might only happen with IOMMU enable.

Should I delete docker.img and libvirt.img and recreating them just in case? 2 hours ago, johnnie.black said: There was a problem with the onboard SATA controller: Mar 9 01:41:23 MXCR-Unraid kernel: ahci 0000:03:00.1: Event logged [IO_PAGE_FAULT domain=0x0000 address=0x00000000e394c000 flags=0x0000] I've seen this multiple times on this forum with Ryzen boards, it might only happen with IOMMU enable. Thanks for the suggestion. I've disabled IOMMU in the BIOS to rule it out. I've started a parity rebuild now and will monitor to see if occurs again. mxcr-unraid-diagnostics-20200309-1437.zip
