Hi,
I have one volume group and that is used as such:
[root@jeff ~]# /usr/sbin/lvscan
ACTIVE '/dev/VolGroup00/Root' [9.78 GB] inherit
ACTIVE '/dev/VolGroup00/Home' [231.31 GB] inherit
ACTIVE '/dev/VolGroup00/Swap' [320.00 MB] inherit
I added a whole disk to VolGroup00 like so:
[root@jeff ~]# dd if=/dev/zero of=/dev/hde bs=512 count=1
1+0 records in
1+0 records out
created the physical volume:
[root@jeff ~]# /usr/sbin/pvcreate /dev/hde
added it to the volume group:
[root@jeff ~]# /usr/sbin/vgextend VolGroup00 /dev/hde
added 100G from the 150G drive to Home:
[root@jeff ~]# /usr/sbin/lvextend -L+100G /dev/VolGroup00/Home
Extending logical volume Home to 331.31 GB
Logical volume Home successfully resized
At this point the docs suggest umounting the logical volume in order
to resize the file system. So I decided I was going to reboot the
computer and start it into single user mode. When doing that I'm
greated with:
lvm exited abnormally!
Couldn't find device with uuid <uuid>
Couldn't find all physical volumes for volume group VolGroup00
So it seems that it can't find the new physical volume that I just
added. LVM is totally new to me, so any pointers would be great.
Booting from CD into rescue mode I wasn't unable to get very far. I
was able to run lvm and pvscan shows this interesting line:
PV /dev/hdf1 VG VolGroup00 lvm2 [ X GB / X GB free]
PV /dev/hdg2 VG VolGroup00 lvm2 [ Y GB / Y GB free]
PV unknown device VG VolGroup00 lvm2 [ Z GB / Z GB free]
Total: 3 [ X GB ] / in use 3
It seems to be that vgreduce is what I want in order to start over,
but running this in test mode with -t and --removemissing I see this
worrying line:
Removing LV Home from VG
and the line I want
Removing PV with UUID {correct UUID}
Am I on the right track?
TIA
