Sanity check, changing 2x BTRFS cache drives to 2x individual xfs encrypted cache pools

[je82]

Hi,

 

I want to change my current config of 2x 1tb ssd as a btrfs volume to 2 separated 1tb xfs encrypted volumes. What is the best way to go about this?

 

My take:

1. Copy all data of the cache volume including docker img etc.

2. Shut down array and all docker containers

 

This is where i am not sure anymore, do i need to do "new config" and then assign all other drive arrays as previous but with the cache volumes i assign them differently?

No need for a new config, just unassign both devices and start the array for Unraid to "forget" that pool, best to wipe the devices before assigning them to the other pools though, if they are SSDs you can do that with

blkdiscard -f /dev/sdX or /dev/nvmeXn1
