Undeletable directory in reiser4

Undeletable directory in reiser4

[Marti Raudsepp]

Hi,

I seem to have found a tripped on a bug in reiser4: there is a
directory on my reiser4 partition that cannot be deleted since it is
supposedly "not empty", however, rm -rf cannot find any more files to
delete.

# rm -rf /var/tmp/portage
rm: cannot remove directory `/var/tmp/portage/sys-devel/gcc-4.1.2/work/
gcc-4.1.2/libjava/classpath/resource/gnu/java/locale': Directory not empty

I mounted the partition as read-only to get some more information out
of it with the debugfs.reiser4 tool. Note that the partition's vartmp/
directory is bind-mounted to /var/tmp.

Is there anything else I can do to help debug this? Will
CONFIG_REISER4_DEBUG help?

Hi,
any ideas about kernel version that generated such

Please, check your partition by fsck.reiser4.
To check root partition, boot in single mode and remount it as
readonly.

Thanks,

Hi,

Forgot to Cc: the mailing list (I'm new to mailing lists), and also
forgot to mention that I'm on AMD64. The reiser4 file system lives on
a contiguous LVM2 volume.

Oops, sorry, I knew I forgot something important in my rushed bug report.
I'm currently running kernel 2.6.21-gentoo-r3 with the appropriate
reiser4-for-2.6.21 patch. At the time the directory was created, I was
running 2.6.21-ck2.

Here's what I got:
CHECKING THE SEMANTIC TREE
FSCK: obj40_repair.c: 223: obj40_stat_unix_check: Node (515), item (19),
[41aac:6c6f63616c6500:41aad] (stat40): wrong bytes (182), Should be (100).
FSCK: obj40_repair.c: 350: obj40_stat_lw_check: Node (515), item (19),

        Found 86670 objects (some could be encountered more then once).
        Time interval: Wed Jul 11 15:41:47 2007 - Wed Jul 11 15:42:00 2007
FSCK: repair.c: 550: repair_sem_fini: On-disk used block bitmap and

differ.
***** fsck.reiser4 finished at Wed Jul 11 15:42:00 2007
Closing fs...done

1 fatal corruptions were detected in FileSystem. Run with --build-fs
option to fix them.

I'll leave the file system in the broken state for now.

Would you please pack metadata by
debugfs.reiser4 -P /dev/xxx | gzip > meta.gz
and let me download the file meta.gz

Thanks,
Edward.

Sure: http://juffo.org/stuff/reiser4_undeletable_dir_metadata.gz

The erroneous directory is located under /vartmp/portage_bug/...
(renamed from its original "portage")

Re: Undeletable directory in reiser4

[Christopher Covington]

Although I don't have any useful information to report because this
happened to me a while ago and I was too lazy to report it or maybe
thought it was my own fault, I had the same problem (indeed with some
work directory of a java package on gentoo). Rebuilding the filesystem
may have fixed it,--'m relatively certain I'm rid of the annoyance now
and wouldn't have taken any steps more advanced than running fsck.
