Interesting.
I would assume that this is not a factor with RAID-1, where all system, metadata, and data is duplicated. I could see this as being very important for the higher RAID levels.
We have since stopped deploying any sort of btrfs RAID (even RAID-1), and have gone back to using Linux MD.

- ansible 6y agoNow that is interesting. If I could mount the failed btrfs filesystem read-write for an appreciable length of time, I could try the balance operation. I'll need to set up a cron job on the other systems to run balance on a regular basis alongside scrub (obviously not at the exact same time).
- codys 6y agoTo be clear: I was running a non-raid (single disk) setup where I found `btrfs balance` to be needed.
