Rollback does not work or: how stupid am I?

[Toydoll]

Yet again a simple task has led to several hours of searching on google and this forum. Yet again am I met with several easy fixes that does not work for me.

So I figured that I would just rollback to before I started breaking stuff. But apparently I'm not even capable of doing that.

I have read the manual and I do think I understand most of it, but yeah, apparently not.

This is what I think snapshots and rollbacks are:
"Bookmarks" from certain moments in time for a certain datasets that I could be able to recreate if needed. Example:
-Have functional jail with plex. Freenas automatically takes two snapshots everyday of that jail. They can be seen under "Snapshots" in the freenas gui.
-Changes are done to that jail which breaks plex.
-After unsuccessfully trying to fix it the user could instead simply rollback to a snapshot that was automatically taken a couple of hours before the changes were made.
-Plex should now work again.

Have I seriously misunderstood anything or is that how it's supposed to work?

This is what happens when I do a rollback:
Nothing.

This is how I (try) to do it:
1. I press the small arrow next to the snapshot I want to rollback to.
2. I press the "rollback" button.
3. I am told that all later snapshots will be deleted and I'm asked to confirm that I really want to rollback.
4. I press "confirm" and "rollback"

What happens then is:
1. I'm asked by a box to "please wait", the box disappears after a few seconds.
2. Nothing is, as far as I can tell changed.
-All snapshots of that dataset still exists even though the later ones was said to be removed.
-Changes that was made to the dataset after the snapshot are still there.

So I guess what I'm asking is if I have misunderstood something or if it Freenas that doesn't behave like it should?

Did you shutdown the jail before trying to rollback? This is not really integrated - the "Storage -> Snapshots" part of FreeNAS does not know what you are using that dataset for.
Make sure to rollback *all* datasets belonging to that jail.

Forgot to mention that but yes, I did do that.

However, luck (or something) has finally found me.

An hour or so after trying to do the last snapshot I went to eat dinner. When I came back I found that Freenas was unreachable through the gui and ssh. I let it be for a while in case it was working on something but eventually I decided to restarted the system.

When it booted up it took a few minutes longer than normal but now it seems to work as it should. And better yet, that pesky jail (Plex) works again. I don't know what happened and in all honestly I'm to tired of this to care. All I bothered to check was that the snapshots that should have been deleted, if it was a rollback that fixed the problem, are still there.

My initial problem still exists though; my plex is on the beta train (or whatever it's called) which I don't want. Having the beta version named "plexpass" was not the kindest decision if you ask me :P


Edit: Nevermind, Plex suddenly stopped working again...

I never had issues rolling an back an iocage to a previous snapshot. This is how I do it from the web gui:
1. jails - select jail - stop
2. storage - snapshots - filter on jailname - sort on snapshot name
3. now I would rollback both the base snapshot for the jail and the /root snapshot for that jail for the specific snapshot time you roll back to
4. jails - select jail - start

You can snapshot a running jail, but I'd advised stopping a jail before rolling back a snapshot and then restarting.

I know it's been a while, but could someone explain step 3 more clearly, what the two snapshots are referring to? And is this a sequence of two rollbacks, or two simultaneous? I'm also unable to roll back a jail.

EDIT:
OK, I now think what may have been meant is roll back both of these snapshots, made at the same time, sequentially:
Ark/iocage/jails/transmission/root
Ark/iocage/jails/transmission

At least that worked for me.

It was my understanding that if you've taken a recursive snapshot of the jail, then you just need to rollback the highest level snapshot (e.g. not the /root one) and restart it. I usually snapshot any databases I might have saved outside of the jail dataset at the same time in case the updates makes database changes and I need to roll back.
