February 28, 20242 yr I tried to reboot, but that didn't seem to help. Attached diagnostics from before the reboot. Any ideas? truffle-syslog-20240228-1751.zip

February 28, 20242 yr Community Expert Solution It's kind of strange the way both disks got disabled, since there aren't any controllers error before, but both look healthy, so almost certainly not a disk problem, especially with two getting disabled at the same time, check/replace cables to rule that out, especially if they share a power splitter or something else, then, and if both emulated disks mount and contents look correct, you can rebuild on top. https://docs.unraid.net/unraid-os/manual/storage-management#rebuilding-a-drive-onto-itself You can do both at the same time.
February 28, 20242 yr Author Oh crap, I powered off the server without recording the actual disabled drives. Where do I see that in the diags?

February 28, 20242 yr Author Thanks! Looks like those two drives are on the same molex to sata power splitter. If I order another one and things spin up, do I have to rebuild?
February 28, 20242 yr Community Expert Yep, but only 43 minutes ago, JorgeB said: if both emulated disks mount and contents look correct
February 28, 20242 yr Author Any reason I can't just bring them back online and pretend nothing happened (or maybe do a parity check)? edit: FWIW, if I look at the drives, all the data seems to be there. Edited February 28, 20242 yr by flyize

That does at least answer this question though: 1 hour ago, JorgeB said: both emulated disks mount and contents look correct But probably better if you post new diagnostics after you get hardware fixes done.
February 28, 20242 yr Community Expert https://docs.unraid.net/unraid-os/manual/storage-management/#what-is-a-failed-disabled-drive Here is a relevant quote: Quote When a disk is marked as disabled and Unraid indicates it is being emulated then the following points apply: Unraid will stop writing to the physical drive. Any writes to the 'emulated' drive will not be reflected on the physical drive but will be reflected in parity so from the end-user perspective then the array seems to be updating data as normal. So rebuilding is the only way to recover emulated writes. And at the very least the failed write that disabled the drives is being emulated. Could be a lot more.

It's actually emulating the whole device? If so, how will I know when I get it fixed? edit: Added diagnostics truffle-diagnostics-20240228-1458.zip Edited February 28, 20242 yr by flyize

February 28, 20242 yr Community Expert If you didn't mount it read-only, then you made it even more slightly out-of-sync with the array. But since you are apparently basing your previous statement 53 minutes ago, flyize said: if I look at the drives, all the data seems to be there on the contents of the physical disk, we don't really know if the emulated disk is mountable after all. 14 minutes ago, trurl said: probably better if you post new diagnostics after you get hardware fixes done.
February 28, 20242 yr Author Okay. So unassign the disks, mount the array. Then navigate through the emulated disks (via the Unraid GUI I guess?) and make sure I see data. Then reassign the disks and rebuild (in-place)?
