[6.9.2] Cache pool shows half of the drive

I'd guess that's because you are using different size of SSDs on BTRFS RAID and the default is RAID1.

Your diagnostics would provide more information about the pool configuration.

Seems consistent :

So probably not a bug.

If you want to benefit from the aggregate size of both drive, there would be some ajustements to do.

Hm what adjustments you suggest, and if i take out 240ssd would be 1tb usable fully?

I think that balancing to single mode would allow you to use the full capacity of both drives.

 

Never tried it, so I suggest that you wait for confirmation by a user with more experience on the matter.

Default for pools is RAID1, available space is correct, if you want to use the full capacity convert to single, of course there won't be any redundancy.

 

 

Changed Status to Closed

Changed Priority to Other

If you mean by convert to single to leave only 1 cache drive thats what i just did, but if there is a way to use both drives side by side please tell me how.

'Single mode' is one of the BTRFS RAID options available. You simply have to balance the pool in that configuration.

 

With both drives in the Pool, open the Pool config page (click on the name of the first device).

Scroll down to the 'Balance Status' section. Select 'convert to single mode' and hit the Balance button.

Then wait for the operation to complete.
