Support often receives questions about repairing a VPS that no longer works. So we have written a detailed general guide.
Since version 2.0, vpsAdmin lets members solve most problems with a damaged VPS themselves, such as a failure to start or a lack of network access. A VPS can break during a system update, after an ill-chosen command or configuration change, and so on.
First, you need to work out why the VPS is not doing what it should. There can be several causes: a full disk, a broken init system or an incorrectly configured network, for example. Most problems can be fixed by mounting the rootfs in another VPS.
vpsAdmin allows any dataset to be mounted in any VPS. So you can mount the dataset containing the broken VPS's rootfs in a working VPS. You can use either playground or another production VPS for this.
The full procedure is in our knowledge base, on the Repairing a broken VPS page.
