You can increase a VMware Ubuntu Server disk size without rebooting the guest OS, but there are important caveats:

• You can expand the virtual disk (.vmdk) while the VM is running (if VMware supports hot-extend).
• But to make Ubuntu recognize and use the new space, you’ll need to rescan the disk and resize partitions/filesystems manually — all without rebooting.

Here’s the complete guide 👇

Goal

You have docker volume on one host and want to move that volume to another host. For example, you want to transfer PostgreSQL container with it's volume to another host.

Solution

Actually, there is no in-a-box solution from Docker, so we need to:

• attach our volume to another container
• copy and archive all files
• copy archive to another host
