Hello, I have been a long time unraid user with no major issues until now. I am having a bit of a head scratcher here. On Feb 1st at the end of the monthly parity check, 2 HDD's were disabled and showed read errors. I took a screenshot and immediately did a safe shutdown. I received replacement hard drives the next day.
While the first hard drive replacement was rebuilding, another hard drive failed during the rebuilding process. This hard drive ended up with a whole bunch of read errors.
I do have dual parity drives but my concern is that since another hard drive failed during the rebuild with already two drives failed, wouldn't that mean the array was unprotected? But, why are they shares not showing up any more?
I am now rebuilding the last failed hard drive, if you view the folder contents through the GUI, it looks like everything is still there, or is that not true and the folder contents is just a cached drive directory being shown?
Quick rundown of the sequence of failure and rebuild
Feb 1st monthly parity check (automatic). Received an email stating parity check failed with two drives showing read errors.
HDD-10 and HDD-14 failed with read errors.
safe shutdown of server to prevent any further loss.
Replaced HDD-10 and started rebuild. (Shares were showing up as normal, nothing alarming yet)
During the rebuild HDD-9 displayed errors on the main GUI screen, the errors kept counting up but the HDD-10 rebuild did complete.
Replaced HDD-9 and rebuild (Shares no longer show up......)
Replaced HDD-14 and rebuilding <----- in progress currently. (Shares still not showing up.....)
The System Log is filled with this error, but I don't know what to do or what it means. Is this a result of a 3rd drive failing during the 1st rebuild?
