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. P.
