Hi !

 

I just built my new Unraid server, firts time doing it !

I'm happy to see it running but I have A LOT of questions ^^

 

First one :

 

I have currently 1 500BG SSD drive to act as a cache drive. I have another 500GB that I'll use to create a cache pool, but I can't use it at the moment.

 

If I configure my Unraid / Docker install (moving Docker appdata to cache drive) and then I add the second SSD to create a pool in few days > will the data on it be erased (reformatting or something) ?

My bad, I think I get an answer by looking at this video :

 

It seems adding a cache drive won't hurt the first drive !!

It depends on the file system.

If it's btrfs then adding drive to the pool will automatically run RAID-1 profile so no erasing.

If it's xfs then the pool will need to be formatted to btrfs i.e. data will need to be erased.

Thanks for this advice

The drives are allready in btrfs so there won't be a problem !

I still would recommend you watch SpaceInvader One tutorial on Youtube just so you don't accidentally make silly mistake.

You're right!

 

Thanks again for your answers 👍
