How to properly expand the volume of the root partition?

Question

linux

Hello.
In openstack, I created a virtual machine
after starting the OS

Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        7.7G     0  7.7G   0% /dev
tmpfs           7.8G     0  7.8G   0% /dev/shm
tmpfs           7.8G   17M  7.7G   1% /run
tmpfs           7.8G     0  7.8G   0% /sys/fs/cgroup
/dev/vda1       5.0G  3.9G  1.2G  77% /
tmpfs           1.6G     0  1.6G   0% /run/user/20226

then I added 195 GB and would like this volume to be expanded
/dev/vda1 5.0G 3.9G 1.2G 77% /
with an additional partition

Disk /dev/vdb: 209.4 GB, 209379655680 bytes, 408944640 sectors

fdisk -l
Disk /dev/vda: 5368 MB, 5368709120 bytes, 10485760 sectors
Units = sectors of 1 * 512 = 512 bytes

lsblk -f

vdb
└─vdb1 LVM2_member       N4Emfs-vvOn-NeWf-oQ6D-jcLV-Mkbx-5Fx0LO

How to do it right?

Answer 1

/dev/vda is not LVM, so no way, just reformatting, transferring data, or mount a new disk somewhere and transfer data to it.
