Hi, I want to setup the RAID. For this I am partitioning the disks .The following is the procedure: fdisk /dev/hde fdisk -n /dev/hde /*to add new partition*/ I specify the first & last cylinder fdisk -w /dev/hde /*save & quit*/ when I do so , I get following : The partition table has been altered! calling ioctl() to re-read partition table. hde:unknown partition table What does this mean? where am I wrong? I am creating a /etc/raidtab file for raid configuration . Then # mkraid /dev/md0 I get error : device too small(0KB). Surprisingly, while bootup itself the Partition check shows : hde : unknown partition table what does this mean & how it affects the RAID setup? hde is the externel disk I am using for RAID setup. I am not able to post any messages to :linux-raid group. with regards, Anil __________________________________________________ Do You Yahoo!? Yahoo!
