That will only tell you what mke2fs would do on that machine. I don't
know if it will be the same on every machine.  You should probably run 

 dumpe2fs /dev/mapper/vg_voinet01-lv_log | grep superblock

If that doesn't work, then I suspect it's not recoverable using fsck. 
If you are sure that it is an ext2/3/4 filesystem on there, then you
can try using something like TestDisk to scan for partitions.  It
should be in epel.
