So I've been working on the server for a few weeks and finally had everything organized (I've used Unraid since the mid 2000s). I've stopped and started the array many times today for various reason. No problems. For piece of mind, I added a second 10TB party drive into an extra bay and everything looks good. No SMART errors, all green lights, etc. I hit start and all hell breaks loose.
First one of the disks (Disk 11) gets immediately disabled. Oddly, this disk got disabled the last time I did a rebuild. I did a filesystem check and repair on many of these disk prior to today. Everything cleared.
Secondly, Disk1 started showing millions of read errors. I panicked and paused the rebuild. Made sure the connection was sturdy (didn't unplug). Resumed the rebuild and now Disk 1, 2, and 4 have the same amount of read errors. And for some reason disk 11 and 2 shows up in the unassigned devices at the same time. When I go into the shell and try to check the disks at /etc/disk1, disk2, disk4...some of the files have ?????? for their file permissions and can't be changed, even as root (read-only filesystem).
At this point, I've just paused the rebuild. I'm not sure what I should do next. If I hit resume, the errors stack up but all the lights are green besides disk 11 (which was disabled). It could complete in 24 hours but...I have a feeling I'm just going to be left with junk? But technically all the data shouldn't be touched since it should only be writing to the 2nd parity drive? No sure what to do next...
