this is steps i made.
1 - /home is one partition with 275Gb
2 - make backup (only 16Gb), and moved a backup to external drive
3 - split with cfdisk into 2 partitions, one with 240 and other with 35
4 - tried install windows xp, didn't have success with it
5 - reboot
6 - undid it, by merging it
7 - mkfs.reiserfs
8 - moved the backup /home and chown the folders to users, and installed libreoffice
9 - reboot
10 - when i log on, i'm notified with message telling me that doesn't find home path
11- check /home, and see nothing, the directory is clean
12- df -h, the output is 240Gb free
13- in Thunar, /home properties i see 275Gb free
here was the problem:
in step 5 in the reboot, /etc/fstab didn't find the /home partitions because a deleted, so he "mounted" /home in root partitions.
in step 6 and 7, i restored the partition, but didn't mount it (cause of the problem)
in step 8 when i restored the backup, the data was in /home directory in root partitions.
in step 9 after another reboot, the /etc/fstab verify that the partitions exist and mounted in /home, that is why didn't find my data.
i saved my data after this, but i still don't understand the step 12 and 13.
