9.3 to 9.10 jail and pluigin changes, what do I need to fix?

[diskdiddler]

Is there a guide on what needs to be done?
I upgraded from 9.3 to 9.10 about 3 months ago and it went well, I was surprised - but I haven't needed to mess with my jails at ALL

Well, I'm about to go to 16GB memory finally and I'd like to work on some more jails.
If I just try and install a new plugin will it break just the new jail or all the other ones? I heard it can be a real nightmare, multiple times.

Any ideas, I'm hesitant to even try

If you just want to use your current jails there is nothing to do. If you want to create a new jail you need to delete all your old jails including the jails dataset. Then you can use the plugins to create new jails that work with freenas 9.10

Wowwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
Seriously?
?

Like all my jails? removed entirely? I can't back them up somehow and import or what?

 

[pirateghost]

I haven't had to delete all my jails to have the ability to add new ones...what the hell you smokin?

huh, maybe i am smoking something. let me check. I have been getting stuff wrong lately and should probably start to keep my mouth shut.

 

[diskdiddler]

I do recall hearing something similar at least to what you said, like all kinds of disaster with the jails.

ok here is one reference of abi incompatibilities that can occur if using a 9.3 jail on freenas 9.10. This isn't directly related to what I said and actually it is even worse than what I said.

 

[pirateghost]

There was talk when 9.10 first came out that jails were just broken. It was suggested to delete all your jails and start over but if you kept your jails, you would be on a hybrid of 9.3/10.0 freebsd version in the jails.

I kept mine and except for the brief period between updates when I couldn't get any networking in some of my jails, they have been working fine and I have created a couple since then.

So i can confirm that this still happens when upgrading from 9.3 to 9.10.1. I tested by creating a plex plugin and standard jail under 9.3 then upgraded. Below you can see the error happens in the plex jail but strangely not in the standard jail.

Code:

root@plexmediaserver_1:/ # sockstat -l

I then went on to create a new standard jail under the new 9.10 install and it downloaded the new freenas-standard-10.3-RELEASE.tgz for the jail which seems to work very good. Still working through some random testing.

Mine continued to work without any problems at all, but I have not in any way tried to make a new one. I heard you needed to update some kind of template repository or something (why the upgrade process doesn't do this, I don't know)

 

[pirateghost]

I've created a few jails and plugins since the upgrade. No issues

 

[Jailer]

I just upgraded from 9.3.1 to 9.10.1 two weeks ago. All my jails continued to function correctly after the update. But being I wanted an up to date base OS for a few of the jails I decided to rebuild them. The 10.3 template downloaded and installed correctly and I've rebuilt all my jails except for one 9.3 plugin that is still running. They are all functioning correctly and I am able to update all of them.

It was a bit of a mess when 9.10 first came out but obviously has been corrected since. I wouldn't be worried about updating at this point but of course YMMV and make sure you have backups before you do just in case it goes sideways.

 

[diskdiddler]

Can I ask why you wanted to update the baseOS for them? What difference does it actually make?

 

[diskdiddler]

Also anyone know if I should use a plugin to install Plex or go the manual route and create a whole new jail manually? I found some of the plugins would not be updated too frequently or would break

They are internet facing so I wanted them up to date. FreeBSD 9.3 reaches EOL 12-31-16.

I found some of the plugins would not be updated too frequently or would break

I think you may have answered your own question.

 

[danb35]

Plex is pretty darn easy to install in a clean jail-- pkg install plexmediaserver followed by sysrc plexmediaserver_enable=YES and service plexmediaserver start.

 

[diskdiddler]

Thanks fellas, when I was a complete FreeNAS newbie the fact the plugins didn't regularly update was mildly annoying and the fact the plugin update process broke my jail / plugins a few times was quite annoying.

At least I'm used to it now. I look forward to this FreeNAS 10 docker thing.
I'll follow a manual plex install guide (although those instructions look pretty simple, thanks dan)

 

[diskdiddler]

Can I confirm a jail should NOT be able to crash the entire machine right? The jail could die but the host box shouldn't just randomly reboot?

 

[pirateghost]

I've never seen a jail take the host OS down, but I suppose it would be possible if you were doing some crazy stuff.

Installing Plex should not bring the host OS down at all.

 

[diskdiddler]

No it's media scanning. I just added 8 more GB (16GB total) and it completely rebooted the machine. I tried with my original 8GB, same issue.
Plex really slaps my HDDs, CPU and memory when scanning and I can't deny I'm close to the PSU limit of my machine but it's been otherwise 100% stable.

I'm going to do some testing in a VM and remotely scan my plex library.
How on earth (sorry?) can I get a FreeNAS 9.10 VM to map my actual FreeNAS box over the network (specifically for Plex)?
