Looking for some advice please.
Due to current pandemic, I haven't had physical access to my TrueNAS server for a number of months. Note that before this, I made a backup which is saved to another machine. Unfortunately whilst away, I received 2 email notifications in relatively quick succession to indicate that both the USB boot drives had failed.
The console is currently showing Solaris: WARNING: Pool 'freenas-boot' has encountered an uncorrectable I/O failure and has been suspended, and I've no access to SSH or the GUI/UI. The server still appears to be running however, as all Jails are operational.
I now have physical access to the server again so need to get the backup restored. My understanding is I need to do the following in order to get the server fully back online and operational.

- Download same ISO as I'm currently running (12.0-U2.1)
- Use the ISO to install TrueNAS to a new USB drive
- Use that USB to boot to the GUI on the TrueNAS server (with the data on it)
- Use the GUI to restore the backup to the working USB drive
- Reboot, and (assuming no other issues) the system should be back working
- Given no access to SSH or GUI, are my only shutdown options press the power button (and hope it does a graceful shutdown), or pull the plug ? ie, without SSH or the GUI, there's no other way to shut the server down ?
- Given the pool was mirrored, do I have to setup a mirrored config before restoring the backup ?
- Do I have to perform the install (and restore) using the TrueNAS box, or can this be done on any machine ? ie, will the above process of installing a new server work on any machine, and is then transferable to a new box, or does it have to be done on the target server ?
- Does the USB drive have to be same make/model/capacity as the existing, or would any variant work ?
- Finally, I've recently purchased a couple of SuperMicro 16Gb SATA DOM's. Can I install them and install/restore the backup to those, or do I need to build using the USB first, then move the boot pool to that ? (ie, is TrueNAS expecting a mirrored USB boot pool, or would a single SATA DOM suffice ?)
