Broke web GUI

[bar1]

not having a great day :-(
after breaking the jails...now the web gui is not showing

404 Not Found
nginx

however nginx seem to be working.....

 

[bar1]

maybe i must revert to a previous snapshot?not sure how to do that....

I'm going to make a lot of assumptions here, but I have a feeling you started up a jail, that uses Nginx, on the same port as your web gui. The reason I think that is because I made a similar mistake a couple of months ago while enabling WebDav. Is this correct?

 

[bar1]

i really doubt it?
also the jails should be on another IP address?

Good point. I'm out of ideas then. :)

thanks, i have another question though.

i am a newbie to zfs and freenas but i was under the impression if anything breaks i can always go back to a previous snapshot....

but i dont see how to do it?

You can go back to previous snapshots though; you need a snapshot to go back to. ZFS doesn't take periodic snapshots. Snapshots are scheduled through FreeNAS. If you didn't setup FreeNAS to snapshot your jails dataset, then you most likely do not have anything to revert to. Check the Snapshots section under Storage to see if you have any snapshots.

FreeNAS will take snapshots of the boot volume but only before upgrades. They are not listed in the Snapshots section. You need to use the CLI:

# zfs list -t snapshot | grep boot
freenas-boot/ROOT/11.2-RELEASE@2018-10-01-20:29:20 1.40M - 838M -
freenas-boot/ROOT/11.2-RELEASE@2018-12-07-07:07:13 13.7M - 850M -
