[linux-lvm] lvextend problem



Hi,
about the *environment* :
[root priscilla var]# cat /proc/version
Linux version 2.4.21-20.ELsmp (bhcompile tweety build redhat com) (gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-42)) #1 SMP Wed Aug 18 20:46:40 EDT 2004

The *problem* :
I extended a logical volume following the procedure

umount -l /dev/Volume00/var

lvextend -L+5G /dev/Volume00/var
e2fsck -f /dev/Volume00/var
mount -l /dev/Volume00/var

The ouput of e2fsck was as following :
[root priscilla var]# e2fsck -f /dev/Volume00/var
e2fsck 1.32 (09-Nov-2002)
Pass 1: Checking inodes, blocks, and sizes
Duplicate blocks found... invoking duplicate block passes.
Pass 1B: Rescan for duplicate/bad blocks

Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information

/dev/Volume00/var: ***** FILE SYSTEM WAS MODIFIED *****
/dev/Volume00/var: 553/1572864 files (14.8% non-contiguous), 706071/6291456 blocks

Now, once the filesystem mounted, I've lost all the data I had on /var (which I didn't back up, I know I know it's extremely stupid, luckily enough this is not a production machine).
For example

[root priscilla var]# ll /var/
total 0

however

[root priscilla var]# mkdir /var/log
mkdir: cannot create directory `/var/log': File exists

??
What happened ? How to get all the data back ?
Thank you

Giulio
