March 10, 20242 yr I may have a problem with one of my Pool or maybe I don't understand something? I upgraded my system and used 2x 480gb Drives from my old Write_cache to upgrade my System_chache. (deleted the write_cache and added the 2 devices to my existing system_chache) Then I change RAID 1 to RAID 5 and now shows a 2TB Capacity, but shouldn't it be 1.5TB? Any Idea what I should do? My plan is to copy every thing to the array and create a new Pool after formatting all SSDs. But that's a lot of work and I don't know if it fixes my issue... My Pools: Pool Settings for "system_cache": The System_chache has now 2x 480GB and 2x 500GB SSD in it.

March 10, 20242 yr Community Expert Solution Pool is correct, but with btrfs the parity size is included in the capacity, used and free space will be correct though, also note that raid5/6 with btrfs is not ready for production, I would recommend using zfs raidz instead.

Thank you! Makes sense, before I had used about 230gb in addition to 500gb for the parity disk which translates to the 730gb used space being reported! Wasn't really intuitive for me. Great Info! Thx Will also make the change to ZFS later.
