# resize2fs -p -F /dev/mapper/mpatha
resize2fs 1.42.9 (28-Dec-2013) resize2fs: Bad magic number in super-block No valid file system found
when trying to open /dev/mapper/mpatha super
piece.
The specific reason is that I use the xfs file system, so I can use the following command to deal with it:
mount /dev/mapper/mpatha /data
xfs_growfs -p -F /dev/mapper/mpatha
