Ori Bernstein (ori@) has sent an "early preview" diff for GEFS, the "Good enough file system" to #OpenBSD tech@. :flan_hacker: GEFS is a new crash-safe, snapshotting, copy on write [filesystem] https://marc.info/?l=openbsd-tech&m=178948744271633&w=2 While still experimental, GEFS has been used in production on 9front/plan9.

Ori Bernstein (ori@) has sent a follow-up mail about his experimental #GEFS port to #OpenBSD tech@, including a updated diff with newfs_gefs(8) utility, and more error handling. :flan_hacker: [...] First off, thanks to Martijn, and everyone else who tried it out and sent patches. Everything is updated and rebased, and the diff has been regenerated with all of the lastest. I've gone through a the error handling code. In theory the filesystem will handle errors mostly correctly. There are probably still places where theory diverges from reality. I've also forward ported most of the important bugfixes from 9front. [..] Some userspace tools have been done (you can now mkfs on openbsd!), but snapshot control hasn't. https://marc.info/?l=openbsd-tech&m=179346643071941&w=2
