Hello,

I am having strange issue with btrfs send/receive:

#btrfs send -p /mnt/a/_btrbk_snap/debian.20160621_1 /mnt/a/_btrbk_snap/debian.20160622 | btrfs receive /mnt/ext/backups/vaclfw/

At subvol /mnt/a/_btrbk_snap/debian.20160622
At snapshot debian.20160622
ERROR: unlink var/lib/samba/private/msg.sock/7992 failed. No such file or directory

But :

ls -la /mnt/a/_btrbk_snap/debian.20160621_1/var/lib/samba/private/msg.sock/
2330 2388 2394 29375 7992

ls -la /mnt/ext/backups/vaclfw/debian.20160621_1/var/lib/samba/private/msg.sock/
2330 2388 2394 29375 7992

uname -a
Linux vaclfw 4.6.0-1-amd64 #1 SMP Debian 4.6.2-1 (2016-06-15) x86_64 GNU/Linux

# btrfs version
# btrfs-progs v4.5.2

What could be wrong?

Thanks

Lubos

Hallo Lubos!

I have got the same problems with send/receive. Had those problems for several weeks or months now. Not sure when those started.

These send/receive problems are known and there are several bug reports all over the internet and also on this list.

Not sure if or when this gets fixed. It's broken atm.

Michael

Hallo Michael,

I would like to help to debug the issue. Something I can do/get logs/whatever to speed up the root cause analysis and get it fixed?

MfG/Best regards,

Lubos

Hallo Lubos!

I am not the right one to adress with this issue.

I, too, am only suffering from the bug, but not
technically apt to address the problem.

You should search this ML and the internet for the appropriate threads and help out there.

I am just a user :)

Greetings, Michael
