> So a year ago i tried to repeat my old trick damaging btrfs (as a user NOT root). Fill the volume with dd if=/dev/urandom of=./file bs=2M && sync && rm ./file then reboot the machine and yes it still works, it's not booting anymore, bravo.
Do you know how ZFS handles that?
- BSDobelix 2y agoWithout any problems. No other Filesystem i tested has that problem (ext4, XFS, ZFS, NTFS, JFS, Nilfs2)
- yjftsjthsd-h 2y agoGood to hear:) My understanding is that it's easier to break a CoW filesystem like that because if you run out of space you can't even delete things (because that requires writing that change), so I'm not surprised that the rest (the non-CoW filesystems) did fine, but I'm happy to hear that ZFS also handles it.
