I had little problem, deleted a 4GB file, but this space was never
freed , but file was gone. So I decided to run -check - no problems
found, next step was to rebuild tree:

Will rebuild the filesystem (/dev/hda3) tree
Will put log info to 'stdout'
Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes
Replaying journal..
Reiserfs journal '/dev/hda3' in blocks [18..8211]: 0 transactions replayed

what shall I do?
while there is no fix currently for this problem you can solve the problem by
expanding underlaying device.
One possible solution is to setup a linear array. In the example below I had
out of disk space with rebuild-tree /dev/loop0,
created 1000 block extention file and losetup-ed it as /dev/loop1,
created linear array /dev/md0 of /dev/loop0 and /dev/loop1
and ran reiserfsck --rebuild-sb /dev/md0 to fix number of blocks in the
filesystem
and reiserfsck --rebuild-tree /dev/md0.
1) dd if=/dev/zero of=ext-1000 count=1000 bs=4096
loseup /dev/loop1 ext-1000
2) create linear raid
mdadm -B /dev/md0 --level=linear --raid-devices=2 /dev/loop0 /dev/loop1
3) rebuild super block on /dev/md0
reiserfsck
