How is a device checked (when being scanned) to contain a btrfs
filesystem? I have a filesystem spread across two devices; one of them
is not being detected; the first (@64KiB) superblock is missing (not
sure why); but the second one (64MiB) seems valid (fs uuid + dev uuid
and all); would i have
Hi Experts,
I have a question about btrfs, have you people integrated
Oracle DIX/T10 DIF into btrfs? If no, do you plan to do
that? And what's the reason?
Thanks in advance,
Nikko

I think I'm on the verge of getting all my data back; the only missing
piece is to recalculate the crc checksum of my altered superblock and
I'm having trouble finding the correct function/method; the data I am
checksumming is (based on the sheet) 0x20 (directly after the
checksum) to 0x32b + n
Some Linux distributions started adding btrfs support in their
installers. Unfortunately, you can't specify your own mkfs.btrfs
parameters, so the best an installer can produce is a btrfs filesystem
made on one partition.
Is it possible to turn a 1-disk (partition) btrfs filesystem into

I think I read/heard somewhere that snapshots can cause pretty bad
fragmentation, because it causes your system to write changes to files
to random locations on the disk, leaving the original inodes intact..
For that reason, I have replaced the directories ~/.config/chromium ,
/var , /usr/portage

Not yet, but I'm pretty sure it's on the roadmap.

Hi all,
enclosed you can find a patch which permits to remove a volume via the
rmdir(2) syscall by an ordinary user.
The rules for a subvolume removal are the same ones of a directory:
- the user must have the write permission on the parent directory
- the subvolume must be empty
