We have done a installation of Ubuntu server 16.10 with LVM disk cofiguration on a customer server and we need to revert our installation to ext4 old disk configuration without losing data. here is disk configuration exported by parted:
Model: VMware Virtual disk (scsi) Disk /dev/sda: 1100GB Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags:
Number Start End Size Type File system Flags
1 1049kB 512MB 511MB primary ext2 boot
2 513MB 322GB 322GB extended
5 513MB 322GB 322GB logical lvm
3 322GB 429GB 107GB primary
4 429GB 644GB 215GB primary lvm
and here is the lsblk out put:

sda 8:0 0 1T 0 disk
├─sda1 8:1 0 487M 0 part /boot
├─sda2 8:2 0 1K 0 part

sdb 8:16 0 650G 0 disk
sdc 8:32 0 16G 0 disk
sr0

we want to move all data to sdb and detach sda.
