This is a rant, it won’t be to long but… So I just started playing with graphite which is just all sorts of awesome. However most of the data I care about needs to come from SNMP, because it’s A, a SAN and I can’t just install some agents, or B) It’s a locked down Solaris […]
Recently had one of the more embarrassing things happen to me at the new job. I spent several hours attempting to figure out my term settings on the Solaris boxes, only to find out that my term was correct, I had just forgotten how to use vi. In case anyone else happens to run into this, it’s important to […]
Just created a new project on google code, pyDepGrapher. I’ve been working on a easy to use dependency generator for a while. It’s much nicer to generate the pretty dependency charts on the computer rather than keep drawing them on the whiteboard at work. Since I recently started a new job, I’ve spent the last couple of weeks doing […]
I’ve been playing around with writing some python tools to get data into and out of bugzilla. I’ve dumped them in google code at https://code.google.com/p/gardens-bugzilla-tools/
Just found out that when setting up a sqlldr job on a windows system when you setup the action you MUST put in a working directory. Otherwise the sqlldr silently fails.
Contrary to old versions now fence_xvm restarts the vm by default. WTF? If it dies I want it dead, as they say, shoot the other node in the HEAD. To fix, create the fence_xvm as a shared fence and then manually edit the cluster.conf file and add option=”off” to the fence section. Stupid stupid stupid
If you have multiple interfaces, and your default route points to a different interface than your cluster communications, you MUST specify the interface when launching fence_xvmd on the physical hosts
Can’t believe I forgot how to attach a disk to multiple machines in XEN, and then my Google-Fu was weak. Finally figure out how though “phys:/dev/device,sda,w!” The important part is the ! after the w. This is to force it to mount.
http://whatexit.org/tal/mywritings/dumb-things-to-check.html Great list of things to check that you never think of. Especially the line endings. That has messed up my puppet configurations more than anything else. Also http://www.ipmsg.org/tools/fastcopy.html.en for a great tool to copy files including all the ACL’s and overcome the 260bit path limit
Just found out that by default Broadcom 10G cards do NOT work with bonding RHEL. Apparently they try to aggregate packets over all connections and in releases previous to 5.2 would cause a kernel panic. You can tell if you are having a problem by NUMEROUS syslog messages saying “recieved packets cannot be forwarded while […]
