February 2, 20215 yr My parity disk became disabled and I started a parity check, but stopped it as I realized there's no point to it. I have a feeling it might be the sata cables or the sata controller on the motherboard as it happened to disk1 a day before and unraid hangs on "stopping array" for hours when I wanted to shutdown to inspect disk1. Which forced me to force shutdown the server. I have posted the diagnostics file before restarting. I really appreciate anyone who helps me figure this out. xio-diagnostics-20210201-1238.zip

February 3, 20215 yr Author I'm going to update to 6.9 to see if it resolves these problems then. Just need to wait for the parity data rebuild to finish. Thanks for the advice
February 3, 20215 yr Author Hi, I upgraded the OS to 6.9rc2 after the data rebuild. Then rebooted and started the array, and now the Cache disks are showing as "Unmountable: No file system", I have attached the diagnostics and a picture. Should I reboot again and see if they get mounted this time? xio-diagnostics-20210203-0716.zip
February 3, 20215 yr Community Expert Cache filesystem is corrupt, likely the result of the previous issues, best to re-format and restore data from a backup, if there's important data and no backups there are some recovery options here.
February 3, 20215 yr Author Yeah the second Cache 2 disk was a mirror of Cache disk so I just swap them. Thank you once again for explaining what happened
February 3, 20215 yr Author Well thinking I was fine, I had to stop the array and the other cache became corrupted as well as I started it up again. I have a question regarding the recovery options you linked. Do these have to be performed while the array is started in normal mode, maintenance mode or not have the array started? Thanks in advanced
February 3, 20215 yr Community Expert If the cache is unmountable array can be started in normal mode.
February 5, 20215 yr Author I was able to restore everything back to normal on wednesday and everything was fine on Thursday, but this Friday afternoon. Parity got disabled and other disks were put to grey status as the picture shows. I couldn't stop the array since it was stuck so I had to do a hard shutdown. Could it be just a coincidence and had bad luck or does the diagnostics show the same thing again? xio-diagnostics-20210205-1458.zip
February 6, 20215 yr Community Expert 9 hours ago, gamer1pc said: does the diagnostics show the same thing again? It doesn't show the beginning of the problem with the disks because there's a lot of other crashing, apparently related to IOMMU, if you don't need it try disabling it and/or look for a BIOS update.
