Is upgrading my box from 9.3-STABLE to FreeNAS 11 really as simple as selecting the new train and clicking Manual Update? That seems way too easy, convenient, and naive.
I've got Plex, SABnzbd, Couch Potato, Sonarr, and VirtualBox (running Windows 7 and a few Window apps) all running in their own jails, and I'd want them all to work afterwards, too. Evidently FN11 replaces VirtualBox with bhyve... so that will require some tweaking, I'm sure.
What other landmines, gotchas, and surprises should I prepare for? Is there a step-by-step Compleat Idiot's Guide I should consult?
RoadHazard,
Recently I upgraded from 9.3 to 11. I used a USB drive instead of the webui update, but I've had 0 issues with my plugins and jails since upgrading to 11. I was also dumbfounded and /very/ pleasantly surprised that it really *was* that easy.
I had constant issues with vbox in 9.3, but rarely needed a VM. after a few hours I would get kernel panics, fs errors, etc etc etc.
Currently I'm in the process of using the webui VM management to handle my Plex, etc as I have more luck with those programs in linux than in the bsd jails I'd used in the past.
From what I understand, if you upgrade and have issues, you should be able to roll back at boot time to your 9.3 install as long as you don't accept the new ZFS flags in FN11.
Look on the forums for using bhyve, there isn't as robust of a management ui as vbox was, and I've run into issues with an ubuntu 16.04 VM that it will hang until FN reboot if I try to reboot the VM with an NFS share mounted. I have to always remember to umount, then init 6.
ETA:
If you're going to install an ubuntu 16 VM (I'm sure other OSs may be impacted), you may need to search for the UEFI boot fix. basically you need to manually boot through the uefi console and then as root create a proper /boot/......... path for the bootx64.efi otherwise the system may not boot.
When upgrading, you may have to rebuild your jails. While they will work in their current state, you won't be able to update any of the software inside of them. Your VirtualBox machines will not come over automatically. There are some posts about this on the forum which you will have to search for.
m0nkey,
Oddly enough, I had the opposite behavior with updating software.
In my 9.3 install pkg update would fail, however running my old jail in 11 I was able to pkg update; pkg install dnsmasq with no issues.
I didn't do any updates to the jails or jail template, but if it was upgraded it was done behind the scenes and was transparent to me.
