Unmountable Cache Drive

[drzaph]

I know this has been discussed before, but I wanted to recap based on my setup. 

 

I had a VM lock up and force stopped it. After that my cache drive became unmountable even after two controlled reboots. I have a pool of two SSD’s with the second mirroring the first. 

 

Do I just format the first SSD that won’t mount and copy/restore data from the second SSD to the first? If so, how do I do the restore process?

 

thanks. 

 

Here’s my logs:

Answered my own question (Thanks AltaVista!). Following this method listed here :

 

 

The third command under Step 1 ended up working:

 

mount -o ro,notreelog,nologreplay /dev/sdX1 /x

 

Now, I'm currently watching MC copy everything from the X mount to a restore folder on my array. Going to reformat the unmountable SSD and copy everything back. Whole process taught me about MC. I was using the Krusader docker UI previously. 

 

Guess I'm glad I didn't stripe the two cache drives to get more space a few weeks ago...
