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?

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?

Of those who are using btrfs send/receive, has anyone gotten in a state

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.

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

Currently, I have a nightly cronjob that rsyncs my SSD to my HD on my
laptop.
Of course, running rsync on an entire FS every night is slow, especially
if I happen to try to use the laptop at the same time.
Obviously, that's what btrfs send/receive is supposed to fix:

It still fixes the problem for me when btrfs won't mount, but it errors at

Are a snapshot of the root volume and a subvolume effectively the same th

I made a mistake and copied data in the root of a new btrfs filesystem.
I created a subvolume, and used mv to put everything in there.
Something like:
cd /mnt
btrfs subvolume create dir
mv * dir
Except it's been running for over a day now (ok, it's 5TB of data)
Looks like mv is really copying all

I had a 5 drive array where the SATA port multiplier one drive was in,
crapped out.
After fixing that, and remounting the array, I got a bunch of recovery errors,
including
warnings. They seem like a lot more than I should have, but maybe they're
normal/expected, maybe not (at the bottom of the mi

See bottom, my filesystem mounts, but apparently it's still corrupted as per
btrfs-image output

Unfortunately my laptop deadlocks from time to time, and too often
it triggers this bug in btrfs which is quite hard to recover from.
The bigger problem is that all the user sees (if anything) is seemingly
unrelated info, namely, "RIP: btrfs_num_copies+0x42/0x0b" or somesuch

Ok, I was wro
First, I used another tool to see how the FS looked like, and maybe in
the hopes of having a list of subvolumes without mounting it:
gandalfthegreat:~# btrfs-calc-size /dev/mapper/bootdsk
Calculating size of root tree
180.00KB total size, 0.00 inline data, 1 nodes, 44 leaves, 2 levels

Hi,
Thanks for the reply and hints.

If any devs want info out of my drive, please ask today, I really need to
fix it tomorrow.
I'll try btrfs-zero-log otherwise and if not, wipe and start over.

Howdy,
I can wait a day or maybe 2 before I have to wipe and restore from backup.
Please let me know if you have a patch against 3.6.3 you'd like me to try
to mount/recover this filesystem, or whether you'd like me to try btrfsck.
My laptop had a problem with its boot drive which prevented linux

Congrats for all having a time machine and fixing my reported bugs in the
