Re: [linux-lvm] vgimport problem



Emmanuel,

the error tells you, that the physical extend count is wrong in the
volume group which might be caused by your hexediting.
What excatly did you do?

That vgimport fails might be caused by out-of-sequence physical volume
number. LVM1 CVS (Branch: LVM_BRANCH_1-0) contains a fix for that which
will be in LVM 1.0.6 as well.
You can display the PV numbers with
"pvdata -P/dev/hdg1 /dev/hdb1 /dev/hdc1 /dev/hde".

But don't change anything _before_ we checked the impact of your first hexedits!
