Resize of partition is ok. Problem is with swap which i missing now.

How to mount/add swap partition?

GUI show only local storage and real memory, there is no virtual memory.

How to add it?

addictionally in syslog I see:

i think it is related to missing virtual memory.

Can you help me how to fix the problem?
