So today, my TrueNAS scale boot drive bit the bullet, throwing a “boot pool is read only error”/not showing up in the BIOS from time to time…
Now, usually that wouldn’t be a big deal except that I don’t have any images of that install and my ZFS pools aren’t exported…
What should I do?
You can just drop in a new boot drive and install from a usb. I do recommend setting up a boot pool mirror though. This way if one goes down, you have a spare that can be used to help recover more quickly.
So the fact that the ZFS pools aren’t exported isn’t an issue?
It doesn’t matter, it might complain when you import but you can just override that.
Yeah. As far as I understand it, exporting is more of a config thing. You can shut down your system asd boot it while missing drives (done this by accident) and boot while missing, and it’ll say there’s an issue with it. Shut down, pop the drives back in and you’re good to go on boot.
But will the new install be able to pick them up?
Oh I see now. You should be able to import them. Worst case is you can’t then you’re back where you are now. There shouldn’t be any data loss.
I really don’t care about the configuration, as long as all the data is safe
Yeah, if it’s ONLY a separate boot drive, the spanned volumes should still be in tact.
