[linux-lvm] LVM - pvmove problems



I think I've just fucked up my LVM device...


I have three 500Gb disks and have now bought
a new 1.5Tb that I was going to move all the
data from the three to and then retire the
three 500Gb disks...
I've done this exact same thing succesfully
before..


I started the pvmove yesterday (on disk 1). Then
the machine crashed... Booted it up again and
ran the pvmove again. It (pvmove) said that
there's already a pvmove running. The command
I just ran is counting up from 0.0% up to 100%
(even though it was about finished when it
crashed). This move took about 15h...


Then this shows up:

----- s n i p -----

Looks ok, eventually...

A 'pvdisplay -v' outputs this:

md7 is disk1, md6 is disk2 and md8 is disk3 which all
is to be removed. md9 is the new disk.


All looks ok, so I continue on to disk2. This is
where the shit hits the fan:

This device was just as full as disk1, but it took
only a few seconds to reach 100% and fail. The new
disk didn't change however:

----- s n i p -----

Anyone got an idea before I starts to cry?! And of
course I don't have a backup - I just didn't have
any possibility to do a backup of 7Tb...
