Well, I have nothing to contribute here, but I’m certainly very interested to hear any replies from those who have used it. I’ve followed it on LWN for a while. Hope it lives up to the hype eventually.
I use ext4 on my personal computer and never considered using something else in checks calendar probably 15 years or so as “it just works good enough for me” (as ext3 did before that). However, bcachefs seems pretty promising (ZFS is a pass as it’s proprietary, btrfs has too many known issues and gotchas for my taste). I’ve read a while ago that it knows 3 “storage targets”: Foreground and background targets that affect writes (data gets written to foreground targets first, later to background targets) and a promote target for caching reads; which certainly will be interesting for writeback cache set-ups (e.g. using SSDs in foreground for caching). I in particular wonder how it compares to dm caching (what LVM uses) in terms of speed and stability in those regards.
Actually, yes, but that was my own mistake. - Made my system partition way too small and installed all of texlive…
However, it took it gracefully, just had to delete a few old snapshots.
These days, I my entire drive partitioned with btrfs and /home / and a few other things in separate subvolumes within that partition.
That works extremely well and allows you to independently snapshot your system (e.g. before upgrades) and your home folder.
It also removes the size restrictions from having “normal” partitons, meaning you’d effectively never have to worry about making them too large/small ahead of time.
[also: Should we make a separate thread? I feel a bit bad about completely derailing the bcachefs discussion here…]
[I reckon we’re doing well with our current vibe. We’re not just hunting down solutions in this post; we’re embracing exploration. It would be even more beneficial and cool if more folks chimed in with their experiences, no matter how small, to spice things up for the community.]
