Re: [linux-lvm] How do I use free PE?



Hi,

your underlying disk /dev/sdb2 cannot be part of more than one volume
group, it'll have to be under VolGroup00.

When you say I don't want to add it to VolGroup00, you may be
confusing some concepts.

You certainly don't want to add free space under / (which is a
filesystem) on top of a Logical Volume (LogVol0) which itself is built
on top of your VolGroup00, isn't it ?

If so, you can create a new Logical volume (let's say
logvolgeneralstorage, man lvcreate) on top of VolGroup00 which will be
mounted on /otherstroragethanslash.

Everything is in the man pages (lvcreate, lvs, lvdisplay, mke[234]fs, fstab)
