Hi Chris,
Any updates on the results of another month of full time work on btrfsck?
Thanks,
Erik.
I've set myself up for disappointment with release dates in the past.
We've found put some really important corruption fixes into the 3.2
merge window, and the current for-linus branch of
Hi Leonidas,
Please check this:
btrfs fi df /home
If this shows much of your space used by metadata then please use:
btrfs fi balance /home
Note that this can take a long (1 day) time to complete on a big FS.

Yesterday I reported a similar problem in this mailing list, in the
thread version.
Running kernel 2.6.37 didn't show this error, but running kernel 2.6.38-
rc2 ended with errors.
Viele Gruesse!

Ah, indeed, just like you I use 2.6.38-rc2. Or to be more precise:

Hi,
btrfs balance results in:

My system: fully up-to-date Fedora 14 with rawhide kernel to make btrfs

kernel-2.6.37-2.fc15.x86_64
btrfs-progs-0.19-12.fc14.x86_64
Filesystem had 0 bytes free, should be 45G, so on darklings
was not umountable. So I still had to reboot.
Thanks,
Erik.

Hi,
Additionally, I cannot mount the filesystem anymore. mount gives no
error messages but hangs in state D.
dmesg shows:
[ 422.323116] btrfs: use compression
Which is a good thing, but it doesn't do anything otherwise.
Thanks,
Erik.

Hi,
I'm not really answering your question, but may I suggest you change
your backup strategy to leverage one of btrfs main features: instead of
using the hardlink-feature of rsync, use snapshots. Btrfs snapshots are
way better than a hardlink-tree, for multiple reasons:
- It uses less
Hi,
I would like to know that the arguments of btrfs filesystem defragment
do. According to the built-in help page, the invocation is as follows:
btrfs filesystem defragment [-vcf] [-s start] [-l len] [-t
size] file|dir [file|dir...]
Defragment a file
Chris, thank you very much for your explanation. Indeed this clears
things up a bit.
Caveat: Defragmenting a file which has a COW copy (either a snapshot
copy or one made with bcp or cp --reflinks) will produce two unrelated
files. If you defragment a subvolume that has a snapshot, you will
Is there a decent way to have btrfs compress already existing files
(that were written before compression was enabled) without hurting any
of the internal structures such as snapshots?
I'm afraid not yet. There is code for this in the btrfs balance
routines, but we haven't yet adapted it
