[expert] Wierd CPU Utilization
This might be something more... like a kernel based problem but sometimes under high load I have noticed the cpu utilization to go to a number of a negative couple thousand. Attached is a capture of vmstat -n 1. Note that the last column is the precent cpu not being used. Jason B.

CHKCONFIG(8) CHKCONFIG(8)
NAME
chkconfig - updates and queries runlevel information for system
services
SYNOPSIS
chkconfig --list [name]
chkconfig --add name
chkconfig --del name
chkconfig [--level levels] name
chkconfig [--level levels] name
-- -
OPTIONS
-- -
--add name
This option adds a new service for management by chkconfig. When a new
service is added, chkconfig ensures that the service has either a start or a
kill entry in every runlevel. If any runlevel is missing such an entry,
chkconfig creates the appropriate entry as specified by the default values in
the init script.

Re: [expert] Unmountable Samba mounts and other oddities
From the man pages for unmount: -l Lazy unmount. Detach the filesystem from the filesystem hierarchy now, and cleanup all references to the filesystem as soon as it is not busy anymore.

Re: [expert] kernel building questions
Have you tried compiling reiserfs into the kernel instead of a module? I know you can use the mkinitrd to make a ram disk with all of the modules you need to load before the file systems can be mounted, but I have found it easier (sometimes) to just compile it in. - Jason B.

Re: [expert] How to request packages?
If you have to build from source (or just want to) use checkinstall and get all the advantages of an rpm's install/uninstall/file tracking! aka: tar xvzf something.tar.gz make make test su root checkinstall make install It works for almost all programs, bind from sources is one of the few that it didn't work with. Note: I have no idea how "distributable" the resulting rpm is, but it works good for installing software on to production servers when they don't have a compiler installed. I'm not sure others on the net would want to use them thou... (Best to stick w/ good mdk rpm's if you can.) - Jason B.

Just curious, I have often times wanted to capture a session while working w/ a server. Do you know of any programs that do this? Even if it only captures the commands it would be great! Jason B.
