I have now managed to fix the problem. I ran vgcfgbackup, then made a copy
of the backup for safety purposes. I than hand edited the original backup
to remove the missing pv (pv4), the root lv and the pvmove0 lv. I then than
vgcfgrestore. Everything is working.
There must be a better way of doing this. Hand editing cfg files is not
safe or sensible. What have I missed?

Hi,
I am struggling to recover from a failed pvmove. Unfortunately I only have
a limited knowledge of lvm. I setup my lvm configuration many years ago.
I was trying to move a lv to a SSD using pvmove. Unfortunately my brand new
SSD choose that moment to fail (never buy cheap SSDs, lesson learnt!").
This is the current status.

I am quite happy to loose the root lv, I just need the home and work lvs.
What am I missing?
Help!
