Networking setup/help
by tdukes＠sc.rr.com 20 May '10

20 May '10

I had to install 5.5 from scratch and now I have to rebuild my home networking system. I haven't had to mess with this stuff in over 5+ years and I'm sure there may be better ways of doing it now. My liunx box acts as firewall/gateway for 2 other pcs. I was using a script from the Linux IP Masquerade HOWTO with ddclient (since I have a dynamic ip). Also, I don't think I need a full name server. Can I get by with a caching nameserver? Thanks!! Eddie

A Directory/Subdirectories Disappeared - which log file to look for this kind of information?
by Wang, Mary Y 19 May '10

19 May '10

Hi, A directory/subdirectories just disappeared on our dev box, and we don't know what happened. Is there a log file that logs this kind of stuff (such as who/date did a 'rmdir'). The /var/log directory has a lot of files and I'm not sure where to start. Thanks in advance. Mary

Generic RAID question
by James Bensley 19 May '10

19 May '10

Does anyone know if using unequal drives in a RAID 0 is possible? I was looking to set up a software stripe but if I have two volumes of unequal size I wish to stripe over, will the OS try and work around this by say only using as much space as is available on the smallest drive or is there anyway it will use all of both drives? Does it have to be a perfect block/byte balance across drives? (I'm assuming yes?) -- Regards, James. http://www.jamesbensley.co.cc/

trying to rebuild an old nvidia driver
by m.roth＠5-cent.us 19 May '10

19 May '10

Let me start by saying that no, I can't get a new card for my user. So, I've got the 96 nvidia driver. I've rebuilt it several times before, and Nvidia's installer's always worked fine. Actually, I have the 73 on my system, and just updated to 5.5, and no problem. HOWEVER, I last rebuilt my user's driver back in mid-April, after the last kernel update (was that mid-March?), and everything was fine... until the other day, when he walked in to tell me he'd had to reboot, and it wasn't working, and dropped him to command line. I rebuilt it... and it dies. As in, sometimes, I have to go to another machine and ssh in to reboot, and sometimes, I have to power cycle his system. I get garbage with the nvidia driver; with nv, I can at least get one of his two monitors working. When I try x with the nvidia driver, it just keeps printing out initializing GART, I think it is (I've lost the log), and then that it has failed to allocate ROP. Anyone see anything like this? I've unpacked the executable, and started working with the makefiles (and yes, I do understand makefiles), but see things like a lot of warning in the compile, and the one that makes me nervous is make CC=cc KBUILD_OUTPUT=/lib/modules/2.6.18-194.3.1.el5/build KBUILD_VERBOS E=1 -C /lib/modules/2.6.18-194.3.1.el5/source SUBDIRS=/scratch/NVIDIA-Linux- x86-96.43.13-pkg1/usr/src/nv modules make -C /lib/modules/2.6.18-194.3.1.el5/build \ KBUILD_SRC=/usr/src/kernels/2.6.18-194.3.1.el5-i686 \ KBUILD_EXTMOD="/scratch/NVIDIA-Linux-x86-96.43.13-pkg1/usr/src/nv" -f /usr/ src/kernels/2.6.18-194.3.1.el5-i686/Makefile modules test -e include/linux/autoconf.h -a -e include/config/auto.conf || ( \ echo; \ echo " ERROR: Kernel configuration is invalid."; \ echo " include/linux/autoconf.h or include/config/auto.conf are mis sing."; \ echo " Run 'make oldconfig && make prepare' on kernel src to fix it ."; \ echo; \ /bin/false) Even though both those files exist and are where they should be. I've googled, and find no references to those, and really hope it's not the card going bad.... So, any clues? mark

CentOS 5.5 - VMware Fencing in Cluster
by James 19 May '10

19 May '10

I'm trying to use the newly integrated fence_vmware script within luci. I add it as a shared device and assume it is setup right (it is added as a device but it doesn't seem to do any connection test). When I try and add my shared fencing device as the primary device to a node it says it is updating the node configuration but then doesn't actually add the fence in the node's configuration within luci. If I try and fence the device it predictably fails to fence the device. I tried using fence_vmware from the command line (which seem to have some trivial errors which keep it from even running) and it works fine (after I fixed fence_vmware). Can anyone offer me advice on setting up the shared fence and applying it to nodes for VMware Fencing?

5.5 install
by Thomas Dukes 19 May '10

19 May '10

Just installed from scratch 5.5 Weird, eth0 is now eth1 and eth1 is eth0. Don't even know how I'm sending this message as the the CentOS machine can't connect to the internet and this windoze box uses the Centos box as a gateway.

Benchmark Disk IO
by Matt Keating 19 May '10

19 May '10

What is the best way to benchmark disk IO? I'm looking to move one of my servers, which is rather IO intense. But not without first benchmarking the current and new disk array, To make sure this isn't a full waste of time. thanks
