Resize disk with umount

# umount device
sudo umount /archive

# resize part
sudo parted /dev/sdb resizepart 1 100%
# This may cause a message that the disk size has changed and the GPT table will need to be fixed.

# resize fs
sudo resize2fs /dev/sdb1

# If you need to check the FS use this command
# sudo e2fsck -f /dev/sdb1


sudo mount /dev/sdb1 /archive

# check fstab
# reboot and check

Resize LVM without umount. Ubuntu 22.04

As you can see the lvm volume doesn't use all allocated space

sudo fdisk /dev/sda

g - create GPT for 2TB+
n - create new partition
1 - number of part, 1 is default
enter - start sector  (2048 is deafault)
enter - end sector (100% is default)
w - write changes
t - change type. it is recomendation
29 - Linux RAID (for list use L)
w - write changes
q - quit

Repeate these steps for each disk you want to use to create the new array. I use 6 disk for create RAID5
