[linux-lvm] reuses an existing LV number

[linux-lvm] reuses an existing LV number

[Joseph Kezar]

I have a situation here where I have to Volume groups

VolumeMailData
and
vg0

I just created 2 more Logical Volumes(LV) on VolumeMailData to make a total
of 4.
I then rebooted and got this error

vgscan - found an inactive volume group "VolumeMailData"
vgscan - found an inactive volume group "vg0"
vgscan - volume group "vg0" reuses an existing logical volume number; please
vgexport/vgimport that VG or use option -f

....

kernel panic: no init found; try passing init=

VolumeMailData gets activated.  But my root (/) is on vg0 which doesnt get
activated and I am dead in the water.

I can detach my JBOD/RAID Array which makes up VolumeMailData so I can boot.
This way it doesnt find the inactive volume group VolumeMailData and vgo is
able to come up normaly

How can I fix this problem, as it is I kinda need both volume groups
functioning simantaniously :)
Thanks,
Joe Kezar

Another thing to add:
Can I change how vgscan is called during bootup?  or is it locked in initrd?
It says to vgexport/vgimport or use -f
So if it boots with -f I should be able to then at least mount my root
partition?

How can I change the manner in which LVM starts so that I can get it to
vgscan with a -f?

Thanks,
A very desperate Joe Kezar

Joseph,

there's 2 options you've got (2nd one looks a bit hacky ;):

a. boot a rescue media with LVM installed on it and run "vgscan -f"

b. presuming you don't have devfs, detach the JBOD, boot from HD, move all /dev
   entries belonging to the JBOD to a different directory (i.e. /dev/.SAV),
   shutdown and reattach the JBOD, boot, move /dev/.SAV/* back to /dev and
   run "vgscan -f"

Regards,
Heinz    -- The LVM Guy --
