Hi,
Is it safe to interrupt a btrfs filesystem defrag -r / by using ctrl-c
or should it be avoided ?
Thanks in advance,

7200rpm or two 5400rpm.

I didn't notice a corruption on other filesystems with kernel 3.17.0.
Also I didn't experience any hangs except when trying to mount a
corrupted btrfs but this was causing a hang within less than 10 seconds.
It could be that your problem is unrelated and that the corruption you
are

Actually it seems strange that a send operation could corrupt the
source subvolume or fs. Why would the send modify the source subvolume
in any significant way? The only way I can find to reconcile your
observations with mine is that maybe the
information can be found in the brtfs send posts.
Did the filesystem you tried to balance contain snapshots ? Read only ones ?

As these to machines are running as server for different purposes (yes,
I know that btrfs is unstable and any corruption or data loss is at my

However I tried to bring my reboot times in relation with

I'm using compress=no so compression doesn't seem to be related, at

Just to let you know, I just tried an ls -l on 2 machines running kernel
3.17 and btrfs-progs 3.16.2.
Here is my ls -l output:
Machine 1:
ls: cannot access root.20141009.000503.backup: Cannot allocate memory
total 0
d? ? ? ? ?? root.20141009.000503.backup
. Maybe this is pure coincidence and has nothing to do with the
fact that it is on SSD or HDD. Another thing I noticed is that for me,
the problem only seems to occur for root subvolumes with many small
files. I have no root subvolumes on HDD so it might be not SSD related.

Hi,
After upgrading to kernel 3.17 btrfs send has stopped working.
ERROR: send ioctl failed with -5: Input/output error

I just tried downgrading to 3.16.3 again. In 3.16.3 btrfs send is
working without any problem. Afterwards I upgraded again to 3.17 and the
problem reappeared. So the problem seems to be kernel version related.

Well, this is only code to demonstrate the problem, the ; is normally a

change anything. With this corrected, the problem stays the same.

Hi,
I completely agree with you. I think lots of people use snapshots for
backup purposes and these ones shouldn't be writable.

Hi,
As I like experimenting with file systems, and as lots of boot cds don't
have the latest kernel/userspace tools, I decided to create my own
bootcd for my personal use. As I think it could be interesting for other
people, I made it available at http://prrescue.prnet.org
