Check if cache is RAID 1 after adding second drive

[Fridleif]

Hi,

 

I've added a second SSD as cache drive. How can I check if it's now RAID 0 or RAID 1?

 

Thank you very much

By default will be raid1, though if using v6.7.2 there's a bug that will make metadata not redundant, but you can check by clicking on the cache device, look for the "btrfs filesystem df:" section

Thank you very much - I found this:

 

 

Data, RAID1: total=46.00GiB, used=44.41GiB

 

Is he expanding the RAID by use? They are 2 x 960GB SSD

Don't understand the question, it's using raid1 where data is mirrored, you can change to other modes, see here.

 

Also and if not converting check that metadata is raid1, because of the mentioned bug.
