[SOLVED] Help! Two disks in disabled state.

[nadmax]

Hi All,

 

I'm sh*t out of luck with 2 out of the 5  (6 including parity) disks in my Unraid setup failing within the space of a couple of days. I've shared a screenshot plus the diag file and some lines from the event log. I have only tried to reboot the system a couple of times, but before I go any further and start unplugging stuff, I would like to know if there is any way to salvage the situation. I have two new drives on the way in the meantime but not quite sure what the consequences are of losing more than one drive in terms of being able to rebuild parity.

Thanks in advance for your help!

Try replacing/swapping cables, both power and SATA, it the disk1 remains missing no way to rebuild disk2 with single parity.

Just a quick update:

• I took my Unraid server apart this weekend and rechecked all the cables - unplugged and replugged all the drives.
• After powering up, only one of the two disks was actually faulty, so I've replaced it and the server is currently rebuilding the array.
