Thank you Greg, that was exactly what I needed. I was looking at pvextend. My
mistake.
I can now create another lv in the resized vg. Thanks again.

I believe you will do the following:
"pvresive /dev/sdb"
That will make the volume group now be 600GB.
Then use "lvextend" to enlarge the logical volumes, and whatever the proper
tool is to extend the EXT3 filesystem.
Best to have the logical volumes & volume group offline ("vgchange -a n")
before starting resizing.
Just my $0.02.

Hello all.
I have an issue, that I am not sure how to address.
How can I resize the physical volume if I change the geometry of the disk
(non-destructive resize of RAID volume at the hardware level)
I can see that the OS has picked up the new size of the disk and I would like
to resize the existing pv. I don't know how.
I started with a hardware raid 5 (400GB), linux automatically recognizes disk
as /dev/sdb
a simplistic representation of the setup is as follows
pvcreate /dev/sdb
vgcreate VolGroup10 /dev/sdb
lvcreate -n LogVol10 VolGroup10
mkfs.ext3 /dev/mapper/VolGroup10-LogVol10
I have added a disk and expand the array to 600GB I can still see every thing
but I don't know how to extend the PV.
filesystems OK
logical volumes OK
volume groups OK
linux sees /dev/sdb as 600GB
pvs shows pv /dev/sdb is 400GB. I wish to, non-destructively, reinitialize
/dev/sdb so that pvs shows 600GB. how?
