==== create a raid lvm aside ====
I had a couple of drive in an external eSATA dock. So first I removed one, put the new storage drive and create a degraded RAID1+ LVM
mdadm --create /dev/md4 --level=raid1 --raid-devices=1 /dev/sde --force
pvcreate /dev/md4
vgcreate nasdrive /dev/md4
lvcreate -L 1.1T -n video nasdrive
lvcreate -L 500G -n music nasdrive
lvcreate -L 2T -n backup nasdrive
lvreduce -L 400G /dev/nasdrive/music
lvresize -l +100%FREE /dev/nasdrive/video
mkfs.ext4 /dev/nasdrive/backup -L backuppc
mkfs.ext4 /dev/nasdrive/music -L music
mkfs.ext4 /dev/nasdrive/video -L video
then copy files from needed drives
then umount the drives :
umount /dev/nasdrive/*
unmount /dev/oldrives
vgchange -a n nasdrive
mdadm --stop /dev/md4
change disk in the dock
mdadm --assemble --scan
vgchange -a y nasdrive
mdadm --grow /dev/md4 --add /dev/sdc --raid-devices=2
mdadm --add /dev/md4 --add /dev/sdc
then final step fill fstab to have it mounted on boot.
