Hello, 
I added a second parttion to vg, extended lv and fs, mounted ir back. Checked -alm directories were in place. Proceeded with creation a few large files * also worked fine. Switched the machiine off and went to bed.
Next day booted to discover that few , but the most important, dies are missing. 

Please advise - I'm extremely upset. Since the back is outdated.
Here is a log from history I could retrive and some additional information.
I run Centos 5.4 rpm based. (2.6.18-164.15.1.el5.centos.plus) with lvm2 ( rpm 2.6.18-164.15.1.el5.centos.plus). I followed the [url]http://tldp.org/HOWTO/LVM-HOWTO/extendlv.html[/url] and 
here is the list of what i have (now):
[code]

[/code]
now here is what i did.
i took the sdb5 and added to VG_STORAGE, extended lvs and extended the FS. Mounted and uuuupps. half of the directories are gone. 
here is the history of commands. All run w/o errors. Well, at least obvious errors that would have caught my eye.
[code]
umount /mnt/storage
vgextend /dev/mapper/VG_Storage /dev/sdb5
lvextend -l+100%VG /dev/VG_Storage00/LG_VG_Storage00_00
lvextend -l+100%FREE /dev/mapper/VG_Storage-LV_00
resize2fs /dev/mapper/VG_Storage-LV_00
e2fsck -f /dev/mapper/VG_Storage-LV_00
resize2fs /dev/mapper/VG_Storage-LV_00
df -h /mnt/storage/
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VG_Storage-LV_00
                      932G  488G  407G  55% /mnt/storage
du -hs /mnt/storage/
487G    /mnt/storage/
[/code]

now, i think i mounted and checked the space.
i ran a couples of commands that created a few big files in the one the directories. Everything went just fine. I never checked if all old directories exist.

Today booted - and all directories/files i created after extension of the fs are in place. Some old dirs are there too. But some (~50%) are missing. Obviously, those are the ones i do care about the most..
Please help....
