How can I recover all my docker & VMs after I replaced my Cache Drive?


Recommended Posts

Hi, 

 

I need help/support.

 

I previously had 4x 128GB SSD drives in UNraid as a cache drive, they were configured so they appeared as 1 large drive (480GB) (all via software in UNraid).

Today I installed a new 1TB nvme drive to replace the 4 old drive.

 

I clearly misunderstood what a cache drive did - I assumed that it only held temporary files (not all my installs Docker containers & VMs) and that those files were written off the cache drive to my array once a day on schedule.

 

I stopped the array and changed the cache drive to my new 1TB drive. I started the array and low and behold all my Docker contains & VMs are gone.

Crap!

 

I stopped the array again, and tried to put the old drives back... but received a warning that doing so will erase the drives.

 

 

So now, I need help, how can I get my stuff back online?
