btrfs wasn't merged into the mainline kernel until 2.6.29.

Hi,
I want to use AWS EC2 EBS snapshot capability and while doing this,
I want to make sure that Btrfs is consistent.
I already know how to proceed when using XFS in the two scenarios that follow:
1) XFS on EBS
Freeze XFS by using "xfs_freeze -f", then create EBS snapshot, then
unfreeze XF
Hi Miao & Chris,

Make the pretty-printer for data sizes capable of printing in ISO
(powers of 10^3), binary (powers of 2^10) or raw (a simple byte
count).
We default to binary sizes, maintaining the original behaviour, but
print (e.g.) MiB to indicate that it's a power of 2^10.

While playing around with resizing volumes recently, I realised
that I didn't know whether btrfs fi show and btrfs fi df reported
sizes in ISO (e.g. powers of 10^3) units, as they appear to from the
labels they use, or in binary (powers of 2^10) units. Also, a mere

I'm sorry about those last mails of mine. Clearly, nobody actually
uses "quilt mail" to send mails. Or at least has never documented
clearly how they do it.
I shall test some more and try again.
Irritated and embarrassed,

It seem that another device doesn't detect as btrfs filesystem anymore.(I think
because its header had been overwritten.) That device is not appear when I run
"btrfs filesystem show".

Hi all,
enclosed you can find a new version of the patch which permits to remove a
volume via the rmdir(2) syscall by a non-root user. The goal of this patch
is to permits to remove a subvolume with a simple "rm -rf" command.
The rules for a subvolume removal are the same ones of a directory:
-
After a reboot you need to do
# btrfs device scan
in order to search all devices which may be involved in a multi devices setup
(like RAID).

UPDATE: I'm currently able to see and read/write some file in degraded mode
but there're many file i can't read with input/output error too.

I had set up btrfs with 2 devices by using command this command sequence.
"mkfs.btrfs -m raid1 /dev/sda1
mount /dev/sda1 /mnt/data
btrfs-vol -a /dev/sdb1 /mnt/data
btrfs-vol -b /mnt/data"
(I was think that it will do raid1 for both data and metadata but I currently

Hi,
I tried to follow this howto

I have an six-drive array I use for television recordings (4 2TB and 2 1.5TB).
Yesterday, I had one of the 1.5TBs die on me, so I did a "mount -o
degraded /dev/sdb /mnt/media" followed by a "btrfs-vol -r missing
/mnt/media", but the latter command almost immediately generated a
kernel BUG message,
