mount in single user mode
 

I have redhat 5.2 server.
/dev/mapper/optlv 32G 4.0G 26G 14% /opt

The systems team is going to attache 200 GB of disk storage
to the server.

I need to expand the mount /opt disk space to 100 GB or add a new mount as /opt with 100GB of disk space. The /opt file system contains 3.9 of data at this time.

How can I do that? thanks

first do not use "single user mode"
run the server normally in "init 3"

if i read the post right
you want to have TWO ( 2) different hdd's mounted to /opt
you do not ,unless they ARE a raid array


now the new hdd could be mounted to /opt/NewDisk

I need only one /opt file system
All I needed is to expand the disk space to 100 GB.

You can expand the optlv logical volume using Redhat's system-config-lvm tool. LVMs can be modified on the fly but make sure you have backups just in case.

Systems unit is attaching 200 GB of disk space. Can I use LVM to expand the /opt file system?

From your 1st post it appears that your /opt is a logical volume so yes.

See Chap 9 http://www.linuxtopia.org/online_boo...ion/index.html

A software or hardware raid may be able to do what you wish along with the LVM solution ZFS would do it and I think btrfs can or maybe will.

Seems it can. http://www.oracle.com/technetwork/ar...s-1734952.html
