[linux-lvm] EXT3-fs: unable to read superblock

[Jean Chiappini]

Thank you for your answer, but when I do this command, this error appear :
tune2fs: Argument invalide while trying to open 
/dev/mapper/VolGroup00-mysqldata
Couldn't find valid filesystem superblock.

The only solution I see now is to format this partition...
