with each new kernel release I really hope that btrfs gets mature enough that I can use it on root and my portage-partition

so that it survives a hardlock or (accidental) power outage without data corruption or loss of access to the contained data


lots of important improvements - I'm curious when the next data loss or corruption messages occur on the mailing list (hopefully less and less or not anymore)

Well, it's mature enough already for normal usage. As long as you don't do anything exotic, it should work fine.

Oh, and I submitted an ebuild of Snapper to Gentoo (Sunrise). It's an excellent addition to btrfs. Hooking it up with emerge (I have a separate script for it, called it "bmerge", that makes a snapshot and then executes emerge) makes it handle everything automatically in a transparent fashion. Instant rollback capabilities!

Somehow I get the feeling btrfs is going to become the emacs of file-systems.

Meaning what, Ragas...? BTRFS is supposed to have all these capabilities, it was part of the design spec.

Assuming that everything works right... you shouldn't lose anything. You should always have the new copy of the data, or the old copy, should never totally fail. I've got it on my arch linux home server as both root and home, have for months, and no problems thus far.

the point is - I tried until a few versions ago and after several weeks it suddenly stopped working (the portage partition)

I use it on a backup partition where it seems to still work but that it almost like a clockwork reliably fails sooner or later makes me feel uneasy


all of these partitions are on top of cryptsetup/luks btw



oh - I didn't ask for this but:

yeah, these error messages look familiar

Yea, that could be put into the "exotic setup" category.

if you assume such things you do not need any of the "improved" features of brtfs.
