this error exist when i want install my own os i build os using build root 2 pls help me..............

opening crypting device
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
fsck.ex2:not found file or directory while opening /dev/mapper/root

You have a typo somewhere calling the filesystem ex2 instead of ext2

You give little detail so I really don't know what you are doing, or where your mistake is. I would check /etc/fstab

fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
fsck.ext2: Is a directory while trying to open /dev/mapper/root

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
mounnting device:/dev/ram.....



my /etc/fstab ---
-----------------------------------------------------------------------------------------------

sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
