[linux-lvm] Trouble with balancing physical volumes with pvmove

Can you give us the output of ‘pvs’ and’lvs’ so we can see your setup?  It’s also not quite clear what failed, a disk?  If so, which one?  

Do you have copy of the lvs and pvs output before your failure?  And what about cat /proc/partitions output as well.
