Hi everyone,
Can someone validate the following process to shrink a container:

I am a bit worried about command:
pct destroy



thanks

You could just restore to a new ID, without destroying old container and confirm that its working first.
Another option is to create a test container and run through procedure to ensure the data consistency.

At first glance the procedure looks ok. Its basically a backup/restore flow.

ok, got my answer.
I was confusing between snapshots types:
vzdump & pct snapshot

vzdump is snapshot of the whole container so I can delete the container once backup is done

Thanks for the answer.
problem is: I have not enough space on the server itself to make a backup of the whole container.
backup and restore to/from a remote server would cost to much downtime.
I am running out of space on the server. I need to shrink overprovisioned containers, migrate them to another server, destroy the zfs pool, add disks, recreate the pool and migrate the containers back....
I am looking for a solution to shrink the container's disk straigth on the container...
