SOLVED GPT went missing... how to recover jails and VM?

[Dave Hamby]

Silly me, non-redundant boot USB nubbin. The GPT got stomped and upgrade installation failed. This led to a reinstall on two new nubbins. The file system recovered nicely but a bunch of configuration went missing including Plex, UniFi controller, and RoonServer. The first two were in jails per the procedures given here. Roon Server was in a BHYVE created VM per instructions at ROON.

Only the boot media was lost and with it the non-storage system configuration. All the zvols and datasets were recovered. Can I just recreate the jails and start them? Can I just recreate the VM and start it?

How should I be backing up configuration data? Is there a fine manual section I should consult? Not being facetious about the fine manual -- it's pretty good but not much on system recovery or best practices.

For the jails, reset your jail root: http://doc.freenas.org/11/jails.html#jails-configuration.

For the config, it's automatically backed up for you to the system dataset. See http://doc.freenas.org/11/system.html#general and http://doc.freenas.org/11/system.html#system-dataset.

Jails are back, thanks.
