Backstory leading to issue:
After a flawless unraid run for years with no disk issues I decided to do some server upgrades and man did the dominos start to fall. I lost 2 hard drives one rebuild after another, luckily the first one happened as I was adding in a second parity drive so it was just emulated and it finished rebuilding so I had two parity drives from that point on. All these failures I think is leading to my issue, some files have even gone missing but not worried on recovering them as they are easily replaceable. 2 other hard drives were starting to show errors during rebuilds so I replaced them as well. One had over 32,000 pending sector errors during a rebuild but unraid never kicked it out of the array, think the issue started right after this happened / I replaced that drive. Which was disk 9 in the array.
Issue at hand:
(Currently running version 6.12.3) After that last drive failure (I think) all the shares vanished off of the shares tab and are no longer accessible on the network. I can see the data on the disks and all the dockers seem to have no issue accessing the data and are functioning properly.
Things I tried:
1. Reboot - No change
2. Upgrade OS from 6.12.1 to 6.12.3 - No Change
3. Removed some old incompatible apps - No Change
4. Upgraded all dockers and applications - No Change
The server is a Supermicro 846 chassis with all drives connected via a backplane so I don't think cable / power issues are to blame here. Plan is to get rid of these old smaller drives and migrate everything over to the 14tb drives as I add in more. Rebuilds were slowing down to 500k at times and only averaged around 45mb/s so there is a definite slowdown on one or more of the drives.
Let me know if you need more info as I'm sure I forgot something important,
Thank You!
