When / how to delete the entire Warden jails? /jails/ dataset?

[diskdiddler]

My iocage jails are working great. I have migrated my warden ones, I have snapshots and everything.
I'd love to destroy the jails entirely just for the sake of being neat.

I'd even prefer to disable the warden service (but I don't think that's possible, yet?)
My system is running on the bleeding edge of what you can do with such a CPU and memory and it's really straining. If I can take out Warden entirely, it would be nice.

Well it seems to me, I've stumbled upon a completely different bug, causing system instability (I thought I was pushing it too hard)

Although, I would still like to reduce the amount of resources, both space, memory and CPU used, so any way to entirely disable Warden, under 11.2 onwards, would be nice.

So the migration script works properly or you remade your jails in iocage?

It doesn't work flawlessly but it works more than well enough and it's 'finished' - I have all my jails in iocage, have nearly for a month. Work fine.

I made a post on how to fix the migration script (it misses about 3 things, each time, consistently) - if you run the script then follow my instructions, jails are then working fine.
I ended up just nuking /jails/ it seems to have worked - took out my snapshots too. Gone, no more Warden.

Love to destroy the service from memory usage to be honest and any templates if I could but I don't know where to locate all that

Sections 1,2,3 I THINK are fixed by Beta 2 (weird iocage networking problems) - don't do them unless you have to.
Section 4 onwards however, you need to do. It's like 5 minutes work, very handy.

That might make a good feature request for the 11.2 series (add a checkbox to disable that service).

Is warden even a proper service? Does it consume any system resources (other than disk space) even without any warden jails running?

I would imagine it's using something, not much but something.

I asked the questions because I don't believe it is. Warden, as I understand it, comprises a set of tools for managing jails, but those tools don't take any system resources (other than a little bit of disk space, of course) when they aren't running. It's my understanding that iocage is the same in this regard. But I'd appreciate more definitive information from someone who actually knows what they're talking about.

 

[diskdiddler]

Obviously something enables it to work, but if it can be shut down or disabled I don't know, it maybe a core OS thing which is built into FreeBSD. Hopefully someone else will provide some insightful information, without smarmy commentary.

I'm pretty sure that both of them are just front-ends for FreeBSD's tools and don't have any daemons, but I too would like to be sure. @Kris Moore, can you help us out?

I think you're correct, judging by the way you see iocage jails listed in the output of jls. warden and iocage are just tools to manipulate jails.

 

[diskdiddler]

Well at least the disk space is saved. I thought my system was suffering from instability due to me configuring all kinds of things in the past 2 months (I'm making use of a lot more FreeNAS features now) - but the issue was the 11.2 file deletion causes a whole system crash bug.

Seriously, the beta 3 release should be moved ahead, there's only 3 left in the queue with 12 days remaining

 

[Ericloewe]

I'm sure it will be if everything's worked through.

 

[fracai]

If it's anything like some of the other releases I've watched, they'll slug a few more issues in from a later release and keep the date the same.

 

[Ericloewe]

That's also possible. Point is, it won't be artificially held back while nothing happens.

There is a daemon and it has been removed for RC1: https://redmine.ixsystems.com/issues/43767 .

So just to clarify, would that indicate the system will auto migrate upon update for users who go straight from 11.1 to 11.2?
I mean surely we won't nuke the daemon, without letting users know / migrating jails?

 

[Ericloewe]

It seems to only be relevant for PBIs. Those have been dead for years, for most people.
