Reallocating Disk Space

[Son Le]

Hi...I was wondering how you would reallocate disk space in HP-UX 11.0. Here is what i get when I type in bdf:

Filesystem: /dev/vg00/lvol3
kbytes: 204800
used: 114479

kbytes: 53329920

avail: 8571618
used: 84%
mounted on: /company

I would like to reallocate some space from /var to /company seeing that on /company it is 84% used up, i would like to move about 2000000 kbytes from /var to /company. How would i do that. Thanks for any help.

Well, they're in separate volume groups which makes it a little difficult. The only way would be to make them both part of vg00, shrink /var and increase /company.

It's normally recommended to keep your data separate from the root vg, which is the way you have it now. I would look into buying another drive and using it to expand vg01.

You can't transfer / reallocate disk space between VGs. A physical disk can be a member of 1 and only 1 VG. A VG can be made up of multiple physical disks though.

The easiest way to add more disk space to your /company LV would be to add another disk to the system, vgextend the vg01 VG to include that disk and then lvexten the /dev/vg01/company LV.

thanks for the quick response guys...much appreciated. I didn't even look at the disk...silly me overlooked that. But you're correct, you can't allocated from a different disk. Thanks for the info.
