I'm curious how the benchmarks are for Btrfs on 6.1, given the improvements that (I think) landed in it: https://www.phoronix.com/news/Linux-6.1-Btrfs

Oh yeah, i like reliable filesystems like xfs or zfs ;)

Wonder if this will make it into Synology DSM 7.2. Seems unlikely based on the timing.

I wonder how this compares to just using mdadm block device level raid5 or raid6. And then a normal filesystem on top.

extraneous files seroed

Though I've used XFS a lot over the years. Mostly because the Debian installer gave 12yo me the choice between ext2, ext3 and xfs, so XFS it was because it sounded cooler.

Btrfs let me down one time and for a file system one time is too many.

Maybe I'm just cynical but I think the ship has sailed for BTRFS RAID 5/6. It's now part of the global mindshare that BTRFS RAID 5/6 == data loss, no one wants to be the guinea pig that proves it works.

Better to direct resources towards bcachefs or ZFS IMO.

Glad to see Btrfs getting continual updates. It's my favorite filesystem for my personal machines (work and home PCs). The feature set is just awesome. I just hope it doesn't get completely abandoned as its development seems to have slowed significantly.

The only thing it's missing before I consider it full-featured is stable RAID 5/6. But it looks like that hasn't been forgotten.

Unlikely, I am on DSM 7.1 and it is 4.4.180+, although I know heavily patched. I have read DSM 7.2 will land 5.10.
