Is this shit finally stable now?

I like water though.

it's useless and always will be. Ext4 is good. Bcachefs will probably be good in the future. No other filesystems are worth using, other than exfat, which is needed for removable media.

What about ZFS, the OG long term storage FS?

RAID1 is fine and has been for quite a while now. (read: pretty much everything with a kernel newer than CentOS 7) If that's what you want then go ahead and use it.

RAID56, every home data-hoarder's dream, is mostly okay but with one big exception: the write hole. They're planning to fix that by adding three and four-copy RAID1, since RAID1 block groups aren't affected by write-hole problems. i.e., you'd make an array with data=raid6 and metadata=raid1c3, both of which will survive the loss of any two drives. There were patches for this posted on the mailing list a few weeks ago, but it isn't getting merged for 5.3 (or probably 5.4) because of a problem with device replacement.

let me guess, you're one of those morons that thinks PAR2 is an acceptable way to protect against bit-rot

on tumbleweed is amazing for snapshots with snapper and you can use for easy rollback (snapshots appear on grub)
only use it for your root partition
it's a very nice thing to have until bcachefs gets mature and optimized (I hope so)

nothing wrong on btrfs, except parity raid5 stuff.

I use it on my system drive for snapshots and for RAID1. Works great so far. Although I want to eventually move to RAID56 and I'm afraid btrfs isn't stable enough. Should I just use btrfs or move to something else, eg. Zfs?

STILL? How long does it take to fix that? I get that it's probably pretty hard to do, but it has been several literal years.
I can almost sympathize with RedHat going full NIH syndrome and making Stratis at this point.
