[linux-lvm] Recovering from a failed pvmove

[Roger James]

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.

This is a recap of what I have tried so far.

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

Help!

Roger
