December 22, 20232 yr I had a drive start throw a ton of errors, but I had a (larger) new drive ready to go, so i started the parity swap following the instructions in unraid's docs. I currently at the copy procedure. I started it just over 24 hours ago. At first it showed the percentage completed. But when i woke up this morning it doesn't, it just says "Stopped. Upgrading disk/swapping parity." and has a greyed out Copy button and the checkbox for "yes i want to do this". I'm still on 6.11.5. Is there any way to tell if its running, or should I just wait for the array start button to appear? I don't mind waiting, I just don't want to wait forever if its not running. nas2-diagnostics-20231222-1659.zip
December 22, 20232 yr Old parity is failing, post a SMART report for old disk1, in case it's not a disk problem.
December 22, 20232 yr SMART for sde new disk1 (old parity?) has several pending sectors, with read errors in syslog. I assume this is the disk it was trying to copy parity from, so all bits of this disk would need to be reliably read to reliably copy parity. This disk does have some age on it as do your other Toshibas, but their SMART looks OK (for now).
December 22, 20232 yr That's current disk1, and old parity, that one is failing, hence why the parity copy aborted, I wanted to see old disk1.
December 22, 20232 yr Author ah ok. that disk isn't installed anymore. is the system safe to shutdown to plug it in, or is there someway to get a historical report? it was up to 2080 reallocated sectors in less than 2 days, from no warnings at all on it.

Start the array and see if you can copy anything important from the emulated disk1 elsewhere, then get a new disk1 and re-sync parity using the new parity disk, or just resync parity without it.
December 22, 20232 yr Author OK i've got the array back up and I'm copying stuff off emulated disk1. So i cant use the new 6TB for disk1 because its bigger, and i'd rather spend money on a 6TB replacement for disk1 instead of a new, smaller drive. So once everything is backed up off disk1, I can remove it from the array somehow, then replace the old parity with the new 6TB, rebuild parity, then put a new 6TB in for disk1? Or is there a better route to go?
