Unmountable: Wrong or No File System on (1) Disk After Power Outage

Featured Replies

Had a brief outage. Family member pressed power button on server briefly (did not hold down). Seems it shut it down unsafely. When I returned and started array, (1) drive is unmountable.

I shutdown the server through unraid and re-seated cables for that drive, but upon powering on and starting array, it is still the same.

Not sure what to do to recover the files on that drive. Containers and files on other drives appear to be present/working.

Any help is appreciated. Thx

I stopped the Array in order to try starting in maintenance mode, but it would not start. So I tried starting the Array again (without maintenance mode checked) and now it won;t start the Array at all

EDIT: I rebooted in order to start in maintenance mode. It worked and I ran a system file check and repair. I think it worked but was hoping you (or someone would look at my current Diagnostics to confirm) Sorry, still learning this OS. Thanks

It was a filesystem issue, should now be fixed, since the disk is mounting.

Got it. Thank you! Was this caused by an unsafe shutdown?
