Another ReiserFS (rpm database) issue (2.6.0-test5)

[Arjan Filius]

Hi,

Finally i "solved" my "rpm --rebuild" problems.

My rpm was on a reiserfs (scsi) partition, and for some while now i've got
problems. Mainly at some point i was unable to install (rpm) packages, and
"rpm --rebuild" failed or just looped forever.

In almost panic mode i tried to resque my system, and installed a similar
system (suse 8.2), copied the rpm database files to that system, and to my
surpise a "rpm --rebuilddb" went smoothly without any error or problem.

Then, copied the "fixed" rpm database files at the original place, and i
was able to install packages again, however a "rpm --rebuilddb"
looped/hanged forever.

In a more relaxed panic mode i searched for differences, and motivated by
the LargeFile ReiserFS problems, i decided i try a "rpm --rebuilddb" on a
fresh ext2 partition.
And with success!

No succes i got with the original rpmdb dir on ext2 and the rpmrebuild-dir
on reiserfs (another partition). (same problem, loops/hangs forever)

I think this problem may have started somewhere 2.5, but i can't easy test
this.

Any ideas? (except for banning reiserfs at all).

At this point i'm still able to reproduce the problems, by doing/debugging
(on a random reiserfs partition):
 strace -f rpm --rebuilddb --dbpath /images/rpmtest/rpm/
