I was looking to encrypt my drives, so I believe I had migrated everything off of my Toshiba 1tb disk. That's to say this failing disk that I am trying to rebuild, shouldn't have anything on it. But I would like to know I know how to rebuild failed disks correctly before the next emergency...
For some reason my Toshiba 1tb disk started failing, it was mounted directly on a pcie card with two sata ports. A second disk (my seagate 2tb) on that card did not fail, so it couldn't be a cable issue, but could be a card issue, I digress...
My two parity drives emulated the failing Toshiba disk, so I ordered a new Samsung 4 tb disk, popped it in, read through https://docs.unraid.net/unraid-os/manual/storage-management/. I am 99% certain I went through the https://docs.unraid.net/unraid-os/manual/storage-management/#normal-replacement Normal replacement process.
As I recall there were 132 errors in the rebuild process, and I through that was weird/bad. (See screen shot)
I thought I would run a parity-check, now I am getting 3418046386 errors, and my 4tb Samsung is showing as unmountable or no file system.
What am I doing wrong?
At some point I rebooted, so I hope that didn't reduce the chance of resolving this.
