manually detached before Kubernetes can attach it to other nodes.

again (due to kubelet restart, for example) will fail. The volume must either
be manually detached first or the pods referencing it deleted (which would

If you need to use a missing instruction, there are two ways to proceed.
One is to update the assembler to support that instruction, which is straightforward
but only worthwhile if it's likely the instruction will be used again.
Instead, for simple one-off cases, it's possible to use the <code>BYTE</code>
and <code>WORD</code> directives
to lay down explicit data into the instruction stream within a <code>TEXT</code>.
