Adding new SDD to cache pool


Recommended Posts

Hi all,

I hope you can help.

 

 

I have an existing cache drive, and NVMe SSD.

I use it as a cache and also the appdata drive for docker containers.

It's backed up nightly to the main array.

 

I would like to add a second to create a cache pool for redundancy.

Is this possible since it has data on it already?

 

Thanks

What file system is in use for the current cache drive?    If it is BTRFS then yes you can add a drive at any time.    If it is XFS then you would first need to back it up elsewhere as a multi-drive pool HAS to use a BTRFS file system.

Thansk, it is BTRFS. 

 

Is there any docs on adding an additional drive?

The title you have given this thread says you want to add HDD to this pool? Not recommended to mix HDD and SSD.

Ah good point, I'm planning on adding a matching NVMe SSD.

But thanks for the heads up.
