Re: [CentOS] Shrinking a volume group

On Tue, Sep 12, 2006 at 02:41:33PM -0500, Steve Bergman enlightened us:

I did something stupid when setting up a server which is now live. I think I'm stuck.

I set up swap on Raid1 which is decidedly non-optimal. I'd prefer 2 independent swap partitions at the same priority.

Here is the set up:

/dev/sda1 + /dev/sdb1 -> md0 (raid1)

md0 -> VolGroup00

VolGroup00 -> VG00LV00(/), VG00LV01(/home), VG00LV02(swap)

I've gotten as far as :

Turning off swap and removing LV02.

Next step would be to shrink VG00. But it looks like you can only shrink a volume group by removing entire PV's. I only have 1 PV.

So I think I'm stuck.

Any ideas?

Yes, leave it as a mirrored partition so when memory is swapped out to a disk that dies, your server does not panic.
