Unfortunately, I can trigger sysrq, but it doesn't get committed to disk and

This got triggered by an rsync I think. I'm not sure which of my btrfs FS
has the issue yet since BUG_ON isn't very helpful as discussed earlier.

Thanks for the patch. Hopefully this will make it to the next 3.15.x
kernel.
I also went back to 3.14 anyway since the 'blocked for 120 seconds' look
like another instance of deadlocks we've been discussing here.
But just curious:

I upgraded my server from 3.14 to 3.15.1 last week, and since then it's been
running out of memory and deadlocking (panic= doesn't even work).
I downgraded back to 3.14, but I already had the problem once since then.
OOM comes in, even though I have 0 swap used and AFAIK all my RAM isn't
gone, it

Thank you for your answer. I'll put the conclusion and question at the
top for easier reading:
So, should I understand that
1) I have enough RAM in my system but all of it disappears, apparently
claimed by the kernel and not released
2) this could be a kernel memory leak in btrfs or somewhere

This looks more serious, and I'm not sure if btrfs-zero-log can help

So I used to use hardlinks to do historical backups of the same filesystem
but I know it's preferable to use refllink with btrfs to avoid having too
many hardlinks.
But if I need to backup this filesystem to another one some other way than
btrfs send/receive (let's say cp -a, tar, or rsync), is it
On my workstation, which unfortunately I can't easily upgrade the kernel on,
so it's running 3.8.0 for now, I've had pretty perpelexing hangs from btrfs
snapshot
when I make a new snapshot every hour.
I see the btrfs snapshot command in iotop for over a minute, and it completes
eventually.

kernel 3.12.7, python 2.7.6-5, debian testing/unstable, bedup installed as per
pip install --user bedup
I tried installing the git version, but the error is the same:
Anyway, with the other bedup, I get:

Does anyone know who the maintainer to send bug reports to, is?

So, I've veen running this for a few weeks, and soon should have
something half decent to share for others to use.
Unfortunately, one of my backups is now failing like so:
btrfs send -p "$src_snap" "$src_newsnap" | btrfs receive "$dest_pool/"
+ btrfs send -p /mnt/btrfs_pool1/home_ro.20140209_12:0
Ok, let me try something else :)
Of those who are using btrfs send/receive, has anyone gotten in a state
where incrementals will not apply anymore?
Thanks,
Marc

If you're collecting them, I found another bug, although it might not
matter to most: if I put my laptop in S3 sleep during a send/receive, it
reliably breaks th

I was trying to make sense out of this:
gargamel:~# lsattr
lsattr: Inappropriate ioctl for device While reading flags on ./satapmtool
lsattr: Inappropriate ioctl for device While reading flags on ./usbreset
As well as the btrfs send issue I reported:
gargamel:/mnt/btrfs_pool1# btrfs send media_ro
Does someone know how I can debug further why this is hanging?
It seems that accessing a certain directory on one of my btrfs filesystems
causes this.
The rest of my system seems ok, as long as I'm not touching this filesystem.
Is this a bug, or a performance problem?

I got this during a btrfs send:
BTRFS error (device dm-2): did not find backref in send_root. inode=22672,
offset=524288, disk_byte=1490517954560 found extent=1490517954560
I'll try a scrub when I've finished my backup, but is there anything I
can run on the file I've found from the inode?

I can confirm this fixed the btrfs send error on my server, thank you.
