Hmmmmmmam. I really like ext4. I wonder why the
change?
Today, you really need a COW filesystem that can easily be dynamically
extended to new disks as needed, a solution to the RAID5/6 inability to
recover in a reasonable amount of time on today's large disks, do not
need the additional complexities of LVM disk management under the
filesystem, SSD erasure tagging, parallel reads/writes, bit-rot
detection and correction, etc. EXT4 cannot handle any of those
problems. EXT2/3/4 were always an interim solution.
ZFS is the cadillac of filesystems, but is proprietary to Oracle. Ubuntu
will underwrite the legal costs for you using ZFS on Ubuntu, but no
other distro will. It is also not well suited to single-disk workstations.
BTRFS gives you 90% of ZFS capabilities, is almost as fast, works well
on single-disk workstations, and is a really good next step for 99% of
users. It has unfinished parts, like RAID5/6 write-hole problems just
like LVM has, and no native encryption yet. Fedora has only partially
moved to BTRFS, leaving the boot mechanism still on EXT2 for unknown
reasons. The Suse distros have been all-in on BTRFS for a lot of years
now, while Fedora only moved to it in 2021. Its been the default Fedora
filesystem for 10 releases now.
Interestingly, Fedora's parent RedHat distro went with XFS instead of
BTRFS for very unclear reasons. Its good too, but the learning curve
for fixing things is very high, and it does not handle the normal
bit-rot issues at all.
