Between single/dup and raid1/raid1
Hello,
today I wanted to remove one drive from raid1, and people at #btrfs advised me
to use ''-dconvert=single'' before ''btrfs device delete''.
I thought of adding ''-mconvert=dup'' too, but the kernel does not let me do that.
It looks like ''dup'' is disallowed for an array of multiple devices. So, to go
back to a single-drive (single/dup) s...

Can't replace a faulty disk of raid1
Hello,
I had a raid1 btrfs (540GB) on vanilla 3.6.3, a disk failed, and removed it at
power off, plugged in a new one, partitioned it (to 110GB, by error), and added
it to btrfs.
I tried to remove the missing device, and it said "Input/output error" after a
while. Next attempts simply gave "Invalid argument".
I repartitioned, rebooted the system, and made the partition grow:

Poor performance of btrfs. Suspected unidentified btrfs housekeeping process which writes a lot
Welcome,
I''ve been using btrfs for over a 3 months to store my personal data on
my NAS server. Almost all interactions with files on the server are done
using unison synchronizer. After another use of bedup
(https://github.com/g2p/bedup) on my btrfs volume I experienced huge
perfomance loss with synchronization. It now takes over 3 hours what
have taken only 15 minutes! File

kernel 3.3.4 damages filesystem (?)
Hallo,
"never change a running system" ...
For some months I run btrfs unter kernel 3.2.5 and 3.2.9, without
problems.
Yesterday I compiled kernel 3.3.4, and this morning I started the
machine with this kernel. There may be some ugly problems.
Copying something into the btrfs "directory" worked well for some files,
and then I got error messages (I''ve not
