[linux-lvm] Help with Resize please?



Hi,

I have a 200GB Raid 1 drive (md0)
On this I set up a group vg00 and two volumes, approx 80G (/dev/vg00/rhome)
& 120G (/dev/vg00/raid) 
These can be dismounted as required.

I've about run out of space on the larger volume and have plenty on the
smaller, so I resized the 80GB volume using
e2fsadm -L -20G /dev/vg00/rhome
This appears to have worked fine, the free space on that volume has reduced
by 20gb.


The problem is that I cannot now extend the other volume; both e2fsadm &
lvextend say there is no free space..
lvextend -- no free physical extents in volume group "vg00"

Vgck shows an apparent problem, but I'm not sure how to fix it:

vgck -- VGDA of "vg00" in lvmtab is consistent
vgck -- only found 30720 of 35840 LEs for LV /dev/vg00/raid (0)
vgck -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" reading data of
volume group "vg00" from physical volume(s)
vgck -- please DON'T run vgscan prior to vgcfgrestore

Vgdisplay shows:

According to fdisk, md0 has 195,360,896 blocks.
I've seen a message with one command (I can't remember which) along the
lines of md0 not being associated with vg00 ???
System is EL3 with all updates to date via yum.

Any help greatly appreciated!

Thanks,
Robert Jenkins.
