Crashes before it even starts scan, when having few btrfs volumes

[spitfire]

I have 2 btrfs volumes (one mounted at /, another one a /strg01). They both have sub volumes. / consists of one drive /strg01 is a raid 10 volume using 4 drives. 'bedup dedup /' runs just fine. But whenever I try to use something else, than '/' as a target (ie. '/strg01' or just run 'bedup dedup' as suggested to dedup all drives) I get an error. See commands I ran to reproduce it.

[g2p]

This looks very similar to #7; please read my comment over there for troubleshooting. Also, what kernel are you running, was it recently upgraded?

[spitfire]

I'm currently running x86_64 Gentoo on 3.8.0-rc2 kernel (you can say I've upgraded it recently, I did it the same day it was released).

python -V Python 2.7.3

'btrfs subvolume list -ap' listed (properly) all subvolumes for every volume I ran it for.

bedup release from pip (that you asked me to install) has different syntax, and doesn't recognize --debug parameter:

??[root@server01] - [~/bedup] - [2013-01-28 10:38:51] ??[$] ~/.local/bin/bedup --debug show /strg01 usage: python -m bedup [-h]

                   ...

                   ...

python -m bedup: error: unrecognized arguments: --debug /strg01

But I can say that this release 'just works' unlike the one from git, but it crashes too:

[g2p]

I didn't mean you should go back to the PyPI version, excuse my poor instructions. The idea was to include ipdb in the dependencies and keep the git version of bedup.

[spitfire]

Ok, so with ipdb, it lists all subvolumes on volume mounted as root '/', which were working well already, but when it comes to /strg01 volume, I get this:

[g2p]

Yup. What does root_info contain so far?

[spitfire]

What is root_info/how do I get it?

[g2p]

--debug drops you into an interactive ipdb shell, just type the name

[g2p]

Basically I want to compare it to btrfs subvolume list to check that everything fills up in the right order.

[spitfire]

It seems wrong. I'll list subvolumes for you. volume '/' doesn't contain '/lxc/' subvolumes, but '/strg01' does

[g2p]

Also, I'd like to confirm that root_id > parent_root_id.

[spitfire]

parent_root_id 1993L

List (correct one) of subvolumes, on both volumes. I don't think it matches info, from root_id:

[g2p]

With -p, sorry. The paths are internal, /strg01 is external.

[g2p]

Ah, with containers and containers/athlonxp I get parent_root_id > root_id, got it.

[spitfire]

What should i start with '-p'? If it's easier, I'm on #btrfs as spitf1r3 now

[g2p]

Nah, I just found the assumption that was broken. When volumes are moved it's possible that parent_root_id > root_id. I'll fix the code.

[spitfire]

Okay, let me know when it's ready to test:)

[g2p]

Here, I've pushed a fix.

[spitfire]

Seems to work fine (doesn't crash at the start), let me wait for the result.

[g2p]

Do let me know, but I prefer to keep this to one problem per issue either way.
