I'm a novice to Linux, what that said I need to install a second hard drive to my system (RedHat 7.1). After physically installing the hard drive what must I do to be able to create two filesystems called /app_data and /backup (at 40GBytes apiece) on this new disk. I know I need to partition it, now sure how, and format it, again not sure how. Finally I need to place the filesystems in /etc/fstab.

Enter the fdisk utility with the command: Fdisk /dev/hdb N (create a new partition) P (primary partition) If you want an extended partition, select E Partition number (1-4) 1 First cylinder ~ (default) Last cylinder ~ (imput a number to indicate the size) +3000M -t (linux partitions are 83 by default and you normally don't need to use this option) Repeat this to create another partition. w (write the changes to the partition table) At the prompt, type: fdisk –l to display the partition information. You will probably need to reboot before formatting the partitions. After you reboot, open the terminal window.... At the prompt, type: mke3fs /dev/hdb1 –L app_date mke3fs /dev/hdb2 -: backup After the partitions are formatted, type: mkdir /mnt/app_date mkdir /mnt/backup Edit the file /etc/fstab to include a line like these examples.... Three examples.... (replace labelname with the name of your new partition) (type id username to get the uid and gid information. 1. /dev/hdb1 /mnt/labelname ext3 gid=500,umask=002 0 0 2. /dev/hdb1 /mnt/labelname ext3 gid=500,umask=002,exec,dev,suid,rw 1 1 3. /dev/hdb1 /mnt/labelname ext3 uid=500,gid=500,umask=002,exec,dev,suid,rw 1 1 That should get you started.

"At the prompt, type: mke3fs /dev/hdb1 –L app_date mke3fs /dev/hdb2 -: backup" That was supposed to be ... mke3fs /dev/hdb2 -L backup

BTW I'm installing an IDE 80-Gb hard drive.

I haven't had any problems with my 80 and 20 gig drives. Also, the statement to format should read... mke2fs /dev/hdb1 –L app_date mke2fs /dev/hdb2 -L backup If you need ext3, try mke2fs -j

I'll use mke2fs to create the filesystems. But I'm puzzled with why I need to create /mnt/backup and /mnt/app_data, what will they be used for? Also, I looked at /etc/fstab and it has an entry for my /oracle filesystem as foll.ows: LABEL=/oracle /oracle ext2 defaults 1 2 Based on this would my new entries be something like this: LABEL=/backup /oracle ext2 defaults 1 2 LABEL=/app_data /oracle ext2 defaults 1 2

My bad, that should have read LABEL=/backup /backup ext2 defaults 1 2.
