if you can afford it get a bigger SCSI drive.
Check how your 2nd SCSI drive is mounted in /etc/fstab
fdisk -l , to see what partitions it has (if it has more then one)
and the names of the drives.
See this to refresh memory http://www.yolinux.com/TUTORIALS/LinuxTuto...torialSCSI.html
format the new drive with fdisk /dev/sgc (if it's id2 , always check it with fdisk -l to see for sure).
create the primary partition, then select write mbr to disk.
then all you do is
mkfs.ext3 -j /dev/sgc1
once done , create a temporary directory on your / , like
mount /dev/sgc1 /newdrive
then you copy all old data from /data (or whatever the name of old scsi is) to /newdrive
cp -a /data /newdrive
once done, check /etc/fstab again to see how the old scsi disk is mounted, comment the line
and add a new line for the new disk and mount it to the same directory.
shutdown computer, remove old scsi data disk , make sure new scsi data disk id is same as old data disk's id , then turn on computer, if all goes well, it will boot up. And you have a bigger hard drive.
