https://askubuntu.com/questions/829392/expand-lvm-logical-volume-on-virtual-machine

now i add a new one. it should be on /dev/sde.
i can't see it on pvdisplay and when try tp fdisk /dev/de1
it says you can create a dos partition.
 
Device does not contain a recognized partition table. Created a new DOS disklabel with disk identifier 0xbc6fc5e9.

Use cfdisk instead.  It's easier to use and it doesn't commit the changes until you tell it to.

After that, you must still mkfs the file system.

And don't forget that linux is not like Windows -- linux does not mount disks automatically.  If the disk will be permanently connected then you must add an entry to /etc/fstab; if it will be connected and disconnected you must mount it manually.
use fdisk /dev/sde
then create a partition table
then mkfs.ext4 -f /dev/sde1
then follow this link to add into LVM

and create entry in /etc/fstab for permanent mount

ASKER

no i can't.
i fund selv the problem. it's because of memory when der is a only 400M back of disk and memory, swap (is in disk) then
problem has nothing to do with partitions. The fdisk warnings about entries not being in disk order.
