Hi Guys i need to know if there is a new quide to replace my cache drive with a new one.

I don't think that some of the docs have been fully updated for 6.12, especially since you can use ZFS for cache pools and the docs don't reflect that.

 

For example:

Note: Details will need to be added for ZFS file systems after Unraid 6.12 is release with ZFS support built in.

 

And:

If you want a multi-device pool then the only supported format for this is BTRFS. If it is already in BTRFS format then you can follow the procedure below for adding an additional drive to a pool

What's the procedure for adding a second cache drive?  I already have one formatted as ZFS and want to add a second one as ZFS.  Do I just follow this (https://docs.unraid.net/unraid-os/manual/storage-management/#adding-disks-to-a-pool) but change BTRFS to ZFS?

You cannot have a multi-drive pool in XFS format.     It needs to be either btrfs or ZFS to have that capability.

Thanks for the reply. So it looks like the Files system is BTRFS. So the whole idea is to remove the old Cache drive and replace it with a Bigger and newer SSD drive.

The old Drive is giving errors.
