/sbin/e-smith/signal-event reboot

==== 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

gdisk /dev/sde #then format as fd00 linux raid the whole drive

mdadm --create /dev/md4 --level=raid1 --raid-devices=1 /dev/sde1 --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 and put the second new drive in the dock, and :

then final step fill fstab to have it mounted on boot.
