[Help]question about VG[Help]

zhangr_2 — Sat, 08 Feb 2003 09:24:27 GMT

a parameter of my VG00 is "MAX PE PER PV=2500"
and right now I have a new harddisk 36G.for some reason I have to add the new disk(36G) to VG00.but for the restriction of the "MAX PE PER PV" I can only use 4M*2500=10G disk space on the 36G disk.and right now the question is how to modify the parameter "MAX PE PER PV" or the size of the PE.thanks 8-)

I am affraid but this parameter can be changed only at the time of creation of a VG with the -e option.
If the VG is already created you can hardly do any thing. This 36GB disk will not be of use in vg00 but if you use it in another new VG you'll get full 36GB.

Hi,

I'm afraid you can't change this once the volume group has been created. To set this at volume group creation time use:

# vgcreate -e max_pe ...

If you absolutely must add this disk to vg00 you could use Ignite to rebuild vg00 with the new value but I would advise that you keep vg00 for the OS only.....its easier to manage, recover etc.

Regards,

James.
