Using LVM to expand existing Linux directory
Posted on 2003-03-17
It is my first time to ask question. I am using Redhat 8.0 for the servers in my office (one with IDE and one with SCSI HDD). Recently, the space for the for the /home directory is running out of space. Someone tell me that I can use LVM to resize and make use of the free space in other partitions (e.g.: /usr and /var) (sorry for using the word 'partition' as I can't think of another better word).
However, when I read the information about LVM, it said that creating the LVM logical volume will distory the information in that directory. As I have never created it before, is it the case if I create one in my server? It is not affordable for me to have another new hard disk.
On the other hand, if I choose to format the harddisk (this is the last step if nothing can do), what I need to do in order that I can resize the logical volume in the server?
The following are some information all the system:
- Redhat 8.0 (kernel 2.4.18-26.8.0)
- with /, /home, /usr, /var, /boot
- LVM module LVM version 1.0.3
- not create any logical group and volume before
Thank you for any suggestion.
