Re: [linux-lvm] How do I pvresize?

[Chris Laycock <LAYCOCKC uk ibm com>]

Glen,

If you do a pvscan do you get  'PV "/dev/sda1"
 etc' or 'PV "/dev/sda"  etc'
If you get the former could you not create
/dev/sda2 with the extra 250GB and add that to the LV as a separate PV
I'm assuming that you can have different
partitions on the same array (actual disk) defined as separate PVs
I may be completely off track here, please
feel free to correct.....

Regards,

Chris.

I have already expanded the RAID slice by 250Gb, and now have a
/dev/sda which is 250Gb larger than it was before.

I now cannot remove that disk without either rebuilding the RAID
on the hot spare(back to square one) or destroying the RAID.

Please, can someone help me?
