fdisk /dev/sdb
Device Boot Start End Blocks Id System
/dev/sdb1 1 9137 73392921 83 Linux

[root@lin-n1 bin]# mount /dev/sdb1 /oradata2 -t ext2
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
or too many mounted file systems

[root@lin-n1 bin]# fdisk -l /dev/sdb1

Disk /dev/sdb1: 255 heads, 63 sectors, 9136 cylinders

Disk /dev/sdb1 doesn't contain a valid partition table


Some one now what is problem?

does /oradata2 exist?

is /dev/sda1 *really* ext2?



is there an entry for /dev/sda1 in /etc/fstab?

it's not supposed to... Partittion table can't be on a partition.

Make sure you have all your scsi services installed...

It probably isn't capable of emulating the device as a scsi device (which the /dev/sdXX entries denote) without one or more scsi services installed as modules...

/oradata2 exist
/dev/sda1 exist and works before i remove rawpartitions
i can see /dev/sda1 in xwindows in Hardware Browser the Hard Drives,
aparently with no problems...
no entry /dev/sda1 in /etc/fstab

I crate another device /dev/sdc1 and work fine

Have you tried rearranging the command?
(Per man page)
mount -t ext2 /dev/sdb1 /oradata2

and create all again
