How btrfs resize should work ?
Hi,
I am working on system storage manager (ssm) trying to implement
btrfs resize correctly, however I have some troubles with it.

# mount /dev/sda /mnt/test

Filesystem creation in "degraded mode"
I''ve had a go at determining exactly what happens when you create a
filesystem without enough devices to meet the requested replication
strategy:
# mkfs.btrfs -m raid1 -d raid1 /dev/vdb
# mount /dev/vdb /mnt
# btrfs fi df /mnt
Data: total=8.00MB, used=0.00
System, DUP: total=8.00MB, used=4.00KB
System: total=4.00MB, used=0.00
Metadata, DUP: total=153.56MB, used=24.00KB

how to find out total capacity and raid level of btrfs file system
I know df does not report the correct size for btrfs raid systems. Is
there any other way to find out the total capacity of a btrfs file
system? Or at least the raid level for data / metadata?
My test system is Ubuntu 10.10 alpha with btrfs 0.19 and a 2.6.35 kernel
(don''t know which rc).
# uname -a
Linux ubuntu 2.6.35-12-generic #17-Ubuntu SMP Mon Jul 26 18:48:06 UTC

I/O error for one folder within the mountpoint
What does the mount log say when you get the EIO error on snooper? Check
if there is a gfid mismatch on snooper directory or the files under it
for all 3 bricks. In any case the mount log or the glustershd.log of the
3 nodes for the gfids you listed below should give you some idea on why
the files aren't healed.
Thanks.

[PATCH] Btrfs: fix a deadlock on chunk mutex
An user reported that he has hit an annoying deadlock while playing with
ceph based on btrfs.
Current updating device tree requires space from METADATA chunk,
so we -may- need to do a recursive chunk allocation when adding/updating
dev extent, that is where the deadlock comes from.
If we use SYSTEM metadata to update device tree, we can avoid the recursive
stuff.

btrfs balance -> hang/crash
Hi,
my btrfs "hangs" when doing a balance operation.
I''m using a 3.7.1 kernel from opensuse: linux-opzz 3.7.1-2.10-m4 #11 SMP

I did a scrub which completed without errors. Then I tried "btrfs filesystem
balance /" which work fine for the first 23 of 46 chunks, then ist stopped

[RFC] New attempt to a better "btrfs fi df"
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi all,
this is a new attempt to improve the output of the command "btrfs fi df".
The previous attempt received a good reception. However there was no a
general consensus about the wording.
Moreover I still didn''t understand how btrfs was using the disks.
A my first attempt was to develop a new command which shows how the

Help interpreting RAID1 space allocation
I''ve created a test volume and copied a bulk of data to it, however the
results of the space allocation are confusing at best. I''ve tried to
capture the history of events leading up to the current state. This is
all on a Debian Wheezy system using a 3.10.5 kernel package
(linux-image-3.10-2-amd64) and btrfs tools v0.20-rc1 (Debian package

Option LABEL
Hallo, linux-btrfs,
please delete the option "-L" (for labelling) in "mkfs.btrfs", in some
configurations it doesn''t work as expected.
My usual way:
mkfs.btrfs -d raid0 -m raid1 /dev/sdb /dev/sdc /dev/sdd ...
One call for some devices.
Wenn I add the option "-L mylabel" then each device gets the same label,
and therefore some other programs
