[CentOS] Installing/configuring a second HD

2011-04-27 Thread Todd Cary
My old server was Centos 4.8 and it is on a HD that is NOT 
connected.  The new Centos 5.5 is the active HD.  Everything 
appears to be working, so my intent is to jumper the old HD as a 
slave, wipe it clean and have it as a backup drive.  Since my 
Linux skills are minimum, I thought it best to heck with the 
experts to find the best (safest) way to accomplish my goal.

I assume that the old drive will auto-mount, however I am not 
sure if it will be identified as a separate due to the Volume 
system (I am not near my server at the moment and I cannot 
remember the exact name that is used for the HD configuration).  
I would notwant to format the drive and find out everything was 
formatted.

It should be okay to do as you describe. If the disk is LVM based, see
my comments below. If it's not LVM based, the worst that could happen
is the system will see the partitions and try to mount them under /mnt
or some such. There's no worry that the system will mount the old
partitions over top your existing ones.

A quick fdisk to remove any old partitions, create new, and your off
and running.

 sure if it will be identified as a separate due to the Volume

If the Volume system you refer to is LVM, then you shouldn't have any
issues with the drive auto-mounting. Been a while since I did this but
I believe you have to tell LVM about the volume group on that drive
before the logical volumes can be mounted.

Not sure about that. Certainly, a little while ago, when I pulled a root
drive out of one server, which was powered down, and shoved it into a hot
swap bay of an identical system, /dev/sdb[123] were created, but since
it's not in /etc/fstab, it wasn't mounted. I mounted it manually.

Removable media do get automounted, but to /media/whatever.
