invalid tlv in cmd tlv type = 816

Hi!

I setup a btrbk remote backup that transfers btrfs subvolumes. Source is a amd64 machine targetting a NSA325v2 with latest kirkwood kernel and bookworm tarball.

It fails with the error message "ERROR: ... invalid tlv in cmd tlv_type = 816" on the target machine.
I found an indication, that this may be a busybox problem: https://github.com/opencomputeproject/onie/blob/master/patches/busybox/feature-onie-syseeprom-command.patch

Any advice how to continue?

I can provide the btrbk config and logs, if needed.

Cheers,
dehn

If you have not done this. The first thing I'd check is if the btrfs module has been loaded:

lsmod

If not then modprobe it.

If it was the reason, then in Debian way, you can add the module loading to either

/etc/modules-load.d/modules.conf 
/etc/initramfs-tools/modules

lsmod|grep btr
btrfs                1466368  1

Yes, it's loaded. A partition is formatted with btrfs and the btrfs tools are working normally, though I haven't tested the btrfs receive command manually yet, which is what is called remotely by btrbk. See below for the exact command:

ERROR: ... Command execution failed (exitcode=1)
ERROR: ... sh: btrfs send '/home/daniel/Experimente/backup/btrbk_snapshots/testb
ackup.20240330T1102' | ssh dnotebook@dbackup.lan 'sudo -n btrfs receive '\''/hom
e/dnotebook/testbackup/'\'''
ERROR: ... invalid tlv in cmd tlv_type = 816

Unfortunately, I am not using btrfs on any of my NAS. Perhaps others might chime in.

Fair enough and thanks for looking, bhodi.
