Fedora 11 Kickstart and SATA drives
Posted on
My Fedora 11 Kickstart installs fail if I have the drive line look like this: part / –size 1 –grow –fstype ext3 I was able to make it work by giving it a real size: part / –size 10240 –fstype ext3 That seemed to make it work. I also noted that this bug has already…
SVN with xCAT
Posted on
This is how I check out the latest xCAT SVN to make code updates. I just added Fedora 11 today. svn co http://xcat.svn.sourceforge.net/svnroot/xcat/xcat-core/trunk/ svn co http://xcat.svn.sourceforge.net/svnroot/xcat/xcat-dep svn ci anaconda.pm -m “added Fedora 11 x86_64 support”
Using IBM Bootable Media Creator with xCAT
Posted on
With a few hacks I was able to get somewhere with this… I wasn’t able to update everything nor restore the bios. 1. I downloaded the tool from IBM site: http://www-947.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=MIGR-5079820&brandind=5000008 2. I put this in the /tftpboot/bomc directory. 3. Copied /tftpboot/bomc/[tcrootfs|tc.zip] into /tftpboot 4. Edited /opt/xcat/lib/perl/xCAT_plugin/dhcpd.pm line 282 made the filename say “bomc/pxelinux.0” instead…
jquery ui tabs and the back button
Posted on
For the site I help out with, xcat.sf.net, I used jquery-ui tabs. The only issue I had was that I couldn’t do back button, and I started getting a few complaints from it… So, after about 20 minutes of investigation, here is the code I used to make it work. It works pretty well for…
IPMI settings.
Posted on
Some times configuring the BMC’s or IMM’s with xCAT is not possible. So you may want to do settings without xCAT. Here are some tricks with our handy tool: ipmitool See current IP settings: ipmitool lan print 1 This is great for looking at IP addresses and stuff. ipmitool -I lan -H 172.29.101.2 -P PASSW0RD…
KVM with RHEL5.4
Posted on
Installing KVM with RHEL5.4 is pretty easy. These were some of my notes that I hope you can somewhat follow along with. I have since done it with RHEL5.5 with the same results. Here’s how I got my virtual machine up: 1. Install Packages [cc lang=”bash”] yum -y install kvm python-virtinst libvirt libvirt-python virt-manager virt-viewer…
NTFS on OSX
Posted on
Apple doesn’t ship support for mounting NTFS partitions read-write. You can mount drives, but you can only read from them. Well that’s not good enough. Go here: https://sourceforge.net/projects/catacombae/files/NTFS-3G%20for%20Mac%20OS%20X/2009.4.4/NTFS-3G_2009.4.4-catacombae.dmg/download No need to reboot, just close the installer when finished, then remount your drive and you’ll be writing like the wind. I use the same drivers for…
VMware Fusion: Specify physical connection
Posted on
In Windows I was able to do this from the VMware interface, but on Fusion I have to hard code it. This link shows how its done: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1001875 Not that cool… But at least its possible.
VMware Fusion on OS X disabling DHCP
Posted on
I do a lot of provisioning on my vmware machines to test features of xCAT. VMware’s built in DHCP server conflicts with my own. I turn it off by issuing: sudo kill -15 sudo cat /var/run/vmnet-dhcpd-vmnet1.pid Then I take DHCP into my own hands.
