I ran mke2fs to locate the backup superblocks:
mke2fs -n /dev/mapper/vg_voinet01-lv_log
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.
P.
