Re: [Vserver] FC5 End of Life and Linux-Vserver

So actually this is more a question for Daniel Zakrisson since he provides the FC5 vserver kernel and vserver-utils RPMs and the repository. How long do you think you'll keep updating the FC5 stuff? Thanks, Rod I guess I'll handle it the same way I handled the FC4 EOL, i.e. keep pushing updates until the base kernel (2.6.20) is no longer receiving them. As for the utils, I hope Enrico will manage to get 0.30.213 in before the EOL, and that should be fine for a while at least. Thanks Daniel. I have a few Vserver hosts based on FC5 and only a partially finished server ( hardware ) to use as a staging/transition system. I see you have the FC6 RPMs in place but my experience with FC6, at least as a workstation, was less than satisfactory so I'm holding/hoping FC7 will be better.

[Vserver] Major Upgrade Question
Hi. I'm using vserver successfully on a production server for over 1.5 years now. I have upgraded without major problems in the past, but it seems that there has been a pretty big change in revision numbers since my last update. This is a Gentoo host vserver and I am running vserver-sources v2.0.2.1 and util-vserver v0.30.212-r1. The upgrade will move me to vserver-sources v2.2.0 and util-vserver v0.30.212-r2. Does anyone think there will be any things I should watch out for with this upgrade? Will I need to upgrade anything in the guest os's after or before I upgrade the host? Thank you Sincerely, John ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
[Vserver] Catalyst Framworks (perl not CISCO) and Vserver
This is going to be very vague but please bear with me. We just rebooted into a new kernel 2.6.20-1.2312.fc5.vs2.2.0.1smp and now the Catalyst test servers (http) will not automagically restart correctly when they detects changes in the .pm files. I see the message it has noticed the changed file but then just sits there until I Ctrl-C and start the server again. This was working with the 2.6.18-1.2255.fc5.vs2.0.2.2.0.rc9.1smp kernel. Anyone familiar with Catalyst and/or have an idea where to look for what is causing this? I'm thinking capabilities but with the change in both the base kernel and the Linux-vserver I could use a clue as to where to look. It is mostly an irritation to have to manually restart the Catalyst test server but I forgotten when I made a change to the application code and wondered why my changes didn't take affect. :-( Thanks, Rod -- ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
Re: [Vserver] Catalyst Framworks (perl not CISCO) and Vserver
I know nothing about catalyst, but had some issue with guest as well, suddenly they turned out no responding anymore. The reason was metalog (inside guest) not processing the log messages it got through /dev/log. I didn't investigate why metalog did not process the log data anymore... Since then I switched over to syslog-ng and network-logging where the issue does not show up (could it be that kernel log client of metalog did block the master metalog process?)

Re: [Vserver] Gentoo and hashified files
Thank you David and Oliver for your replies. I am glad to see there are other using Gentoo with vserver happily, but it's disappointing that noone seems to be using vhashify. That's would be nice to have since I plan on having up to 60 vhosts. Oliver: I am somewhat amazed that your setup works. I would think Portage would get very upset, or at least confused, when packages that aren't marked as updated are, dependencies should be broken etc. But two years running is quite stable. Is it just /var and parts of /etc that are externally mounted, while /usr, /lib etc. are all shared? Cheers, Einar Oliver Welter wrote: This might be offtopic but perhaps useful. I have multiple guests that share the same root directly. All configuration and runtime relevant dirs (var and parts of etc( are mounted from a per guest partition.

[Vserver] disk scheduling ?
A question - is it possible to have something like the CPU token mechanism, but for IO operations (f.e. hdd-s) ? I have a problem where one of the contexts is really heavy on IO and I'd try to limit that. The scheduler is CFQ, but that does not help much on itself, it's not the scheduling itself that is the problem - if the HDD activity is high, an another context, running apaches will slow down serving files. Running out of children bc of the slowdown apache will start forking new processes to fullfill the incoming demands, this however triggers swapping after running out of ram which in turn makes everything even slower, starting a nasty IO bound load spiral. To make things (maybe) even harder, the IO intensive context is not actually reading/writing all that much data but rather seeking among small blocks of it. Is there a recommended/usual way of solving IO bound problems among vservers ? Putting in CPU limits or tokens does not help as the CPU-s are spending their time on idle or waiting even now so they are always full of tokens. ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
Re: [Vserver] Major Upgrade Question
I upgraded from linux-2.6.17-vserver-2.0.2.1/util-vserver-0.30.212-r2 to linux-2.6.20-vserver-2.2.0/util-vserver-0.30.213 about a month and a half ago. Didn't have any problems at all. YMMV, though.
