Hi
i'm having a problem with reiserfsck, version 3 and
as namesys is no more, i dont known exactly where to go to ask
for help... i'm trying here :)
i have a 170GB partition that during a download
got about -16TB of free space... i checked the log and
got no kernel error nor message.
as it was wierd i dismounted the partition and run
a reiserfsck --fix-fixable on it... it complained that had
2 errors that needed the rebuild-tree.
As recomended, i run the rebuild-tree (first time
without the --scan-whole-partition) and got the error "out
of disk space" in the end...
Could you build and try reiserfsprogs-3.6.20?
http://www.kernel.org/pub/linux/utils/fs/reiserfs/reiserfsprogs-3.6.20.tar.gz
so i run it again like this:
# reiserfsck --scan-whole-partition --rebuild-tree /dev/sdb7
reiserfsck 3.6.21 (2009 www.namesys.com)

** Do not run the program with --rebuild-tree unless **

Will rebuild the filesystem (/dev/sdb7) tree
Will put log info to 'stdout'

out of disk space

# echo $?

So i can't mount the filesystem, as the rebuild didn't finish,
nor i can finish the rebuild, as it keeps giving out the "out of disk
space" error... if the "out of disk space" is true, i have many files i
could erase, but as i cant mount, i'm in a deadlock. whatever corruption
i have, this version of reiserfsck is unable to fix it...
i already done a dump of the metadata:
debugreiserfs -p /dev/sdb7 | bzip2 -c> /tmp/metadata.bz2
The system is a slackware64 -current and main kernel:
Linux Caravela 2.6.37.1-k8_64-kms #33 SMP Sat Feb 19 05:27:52 WET 2011
x86_64 Dual Core AMD Opteron(tm) Processor 175 AuthenticAMD GNU/Linux
So, is there anyone with time and will to help me
recover this partition? :)
Thanks in advance for any help
higuita
ps: might be a coincidence, but since i changed to 2.6.37-1 i
have run 2 --fix-fixable on other reiserfs partitions and this
--rebuild-tree. As i said, its probably a coincidence, but just
in case...
