I have notice there are quite a few people watching the now 11 month old video on filesystems for 2022. There have been so many updates to the linux kernel to address issues in Stratis Filesystem and btrFS that I thought I better retest and see if some of the performance problems I uncovered have been fixed,. TL;DR is btrfs fixed? is it now safe to use for RAID 5 and RAID 6. It's coming along, but I wouldnt trust its RAID 5 or Raid 6 on a bet. Its still not ready for that kind of use. However, there are some major performance improvements and some quirky behavior that I have seen, more about that in a later video.
