I am experiencing the above problem and I have no idea what caused this. Can someone help me figure this out?
1) I have already had my first disk /dev/sda
working properly, now I am trying to create another FS on the 2nd disk:
$fdisk /dev/sdb
[I pressed n, p, w under fdisk]
2) I took a look at the result of fdisk
$fdisk -l
Disk /dev/sda: 1999.0 GB, 1998998994944 bytes
255 heads, 63 sectors/track, 243031 cylinders, total 3904294912 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

3) I make the following filesystem
$ mkfs.xfs -i size=1024 /dev/sdb
4) Now I see the problem...
$tune2fs -l /dev/sdb1 |grep -i inode
tune2fs: Bad magic number in super-block while trying to open /dev/sdb1
Couldn't find valid filesystem superblock.
