Re: [Vserver] setting /proc/sys/kernel/shmmax on the guest (solved)
Thanks to Bertl and daniel_hozac this is solved already.
Most recent util-vserver tools (0.30.213-rcX) from
http://people.linux-vserver.org/~dhozac/t/uv-testing/ can do this.
Just create files
/etc/vservers//sysctl//{setting,value}
holding the key and the value.
E.g. here it looks like this to change shmmax:
# cat /etc/vservers/testguest/sysctl/kernel.shmmax/setting
kernel.shmmax
# cat /etc/vservers/testguest/sysctl/kernel.shmmax/value

I am just running into this very same problem. However, if the above is a solution I don't understand it. So far I tried adding this line to prepre-start and making prepre-start executable as well as just setting this as an environment variable before calling the vserver start. Both ways result in just no shmmax changed. For another attempt I added to vserver.start above the "[EMAIL PROTECTED]" \ an $_CHAINECHO /proc/sys/kernel/shmmax 134217728 -- \ unfortunately this stops the vserver from starting and I actually don't understand what parameters would be correct for the chain-echo.

ah, but that script could actually 'enter' the
context with capabilities still intact and
do whatever manipulation necessary ...

To begin with Happy new year to every vserver guy.
and a happy new year to you too ...
I have to extand the shmmax for my guest but I do not manage to do it.
cat /proc/sys/kernel/shmmax
134217728
I have tried the /etc/vserver/host/rlimits
I have tried to add bcapability
but I do not manage to go ahead with it.
I've run under 2.6.19.1 with the last devel vserver patch under
debian etch as host.
Could somebody tell me how to modify the guest config to execute
"echo 134217728 /proc/sys/kernel/shmmax " for my guest.
as 2.6.19.x incorporates the mainline namespace
stuff, you have to set those values from one of
the early guest startup script (e.g. prepre-start)
while you still have 'enough' capabilities ...
I assume this requires the IPC namespace to be created?
That doesn't happen until the context is created, so none of
the scripts would work for this particular problem.
hmm, isn't the context supposed to exist in
the post-start script? if not, please could
you once and for all clarify which script is
started when and in what context(s)?
The context will exist in the post-start scripts, but they won't be run
inside the context, and the context will already have lost the extra
capabilities.
Having a non-executable one that does something like
VSERVER_EXTRA_CMDS=( $_CHAINECHO /proc/sys/kernel/shmmax 134217728 )
is probably the only way to make it happen (with current tools).
okay, any plans to allow for such support?
also using the sysctl interface instead of the
deprecated procfs one (which might as well be
hidden away :) is advised ...
maybe special tool support will be added soon,
so please double check with the tool maintainers
I guess some nicer way to support it would be required,
especially as more of these settings become available.
what do you have in mind ... please share
your thoughts, as I think those settings _might_
become essential for certain setups ...
I guess something like /etc/vservers//sysctl//{setting,value}
shouldn't be a problem, should it?
TIA,
Herbert
HTH,
Herbert
