Boot environments deleted after upgrade......
We upgraded from 9-10-2-U6 to 11-1-U1 (details here: https://forums.freenas.org/index.php?threads/upgraded-9-10-2-u6-to-11-1-u1-periodic-crashes.61358/#post-436415) and was, following recommendations, bugged here: (https://redmine.ixsystems.com/issues/28249#change-164553).
We decided to roll back to the previous version with which we had no problems (9-10-2-U6), and if our understanding of the docs is correct, should be able to do that by choosing a previous boot environment in GRUB at system boot.
The old environments are listed in Freenas (screenshot), but in GRUB only the single option for the current environment is available. It seems that all previous environments have been deleted.
We upgraded by selecting the new train in Freenas and did NOT upgrade the pool flags.

Aside from having a lot of BE's (15+) the config looks fine. I'm unsure if there's some upper limits on how many can be loaded into GRUB's memory.
Can you go into the FreeNAS BE's menu and clean up a couple of the old stale ones? Once thats done, reboot and in the GRUB menu try going to the 2nd option to select old BEs. Does anything flash on the screen like an error real quick, or does it list anything at all? Could we get a couple pictures of that screen?

Ok, I updated the available list of BEs, see screenshot. However, when booting as you will see from the attached photo, only the OLD environments appear in the list.
When I first tried to delete a single old BE I got an error, I have included those screenshots for completeness.

Checking the system this morning (related to the spontaneous reboots), I noticed that the version after a restart is 9-10-2-U6 (see attached).
This despite the fact that that BE did NOT appear in the Grub menu. In fact, that option had been selected in the System > Boot menu for a while, it was just ignored until now.
Hope that helps.........
