Ext4 physical volume with rescued data to LVM

I have /dev/sdc where are rescued data from VG vg_data. I need convert /dev/sdc to LVM with this data. Is it possible?




Edit1:
- I formatted /dev/VG_DATA/data from xfs to ext4
- Copied from sdc1 to LVM data (I thinked)



After I run rsync from sdc1 to data lvm i got errors and /dev/sdb1 (lvm data) is gone to offline.

What is wrong with volume group? It is virtual mach. on hyper-v 08 r2




Edit 2 - from boot log
