Hi all,

I'm in the progress of switching a WD15EADS-00P8B0 disk to a  Samsung F2 
1.5TB drive because of all the reouble associated with the WD drives 
regarding 4kb block, system freeze and poor performance.

I unmounted the VG and began doing a pvmove.

At first it went well but after 30-40% done it began complaining big time.

What is happening here and should i be worried the data will be lost? I'm 
not very good at LVM so I'm very worried right now.

Thanks for any input on this
