Hmm, I've mounted prioc in all my jails but top won't work anyway: $ top kvm_open: short read top: kvm_read for _ccpu: Unknown error: 0 On Tue, 21 Dec 2004 12:20:13 +0100, Ruben de Groot [EMAIL PROTECTED] wrote: On Mon, Dec 20, 2004 at 05:31:52PM -0600, Frank Knobbe typed: On Tue, Dec 21, 2004 at 12:13:08AM +0100, Daniel Johansson wrote: I see.

Otherwise they get out of sync as you suspect.

Re: Do I have to rebuild my jails too when I rebuild the server?
Okay, I see. I've not done this with my jails so I think it's time to do it But until now everything has worked anyway, upgraded from 4.9 to 4.10-p5. How important is it to rebuild the jails too?

I don't think it has to do with importance. Rather it has to do with correctness. Jails use the running kernel. You have to rebuild kernel and world together to prevent them from getting out-of-sync (easy to test with top). Hence, you also have to rebuild your jail-world when you rebuild your kernel.

Re: Do I have to rebuild my jails too when I rebuild the server?
I see. So if I've got a synced jail and host then top will work? I thought top never worked inside jail for some memoryissue or something like that? I think I should go and rebuild my jails too. It's just a bit of work with three jails, thank god that I've got a fast box :) Still the issue with config-files but I think I'll back them up and just restore them.

Would still be a good idea to run mergemaster for the jail to keep the configfiles up to date. Yes, run 'mergemaster -D /your_jails_rootdir' from your host. Answer the question Use 'd' to delete the old /var/tmp/temproot and continue with 'd' or simply type 'yes' when mergemaster asks, if you wish to delete what is left of /var/tmp/temproot. I mostly run a small script that runs installworld, cleans out /usr/include/* and runs mergemaster for every enabled jail it finds in /etc/rc.conf. I run it on 5.3. The bad thing is, that it depends on ng_rc-style rc.conf, so it doesn't work on 4.11. However, if you will ever run 5.3 - feel free to use it, modify it or recycle-bin it. -- Christian Hiris [EMAIL PROTECTED] | OpenPGP KeyID 0x3BCA53BE OpenPGP-Key at hkp://wwwkeys.eu.pgp.net and http://pgp.mit.edu pgpovqpb9VGs2.pgp Description: PGP signature
