As tiburon progresses …

We are now booting: Redhat 6.1, Centos 6.0, Ubuntu 11.04, and others (including VMs!) via tiburon. Completely painless for compute and storage nodes. This is letting us get to the next phase: Application Specific Nodes (or “appliances on demand” in more common language). Basic idea is, spend zero … identically zero time on your expensive […]

Semi OT: New laptop is in

Have Linux loaded. And windows 7 pro (actually upgraded from the windows 7 home they had). Ok … I like it. It is very fast. About as heavy (maybe a little more so than the Dell). Keyboard is a chicklet style. I’m ok with this, Dell had a more standard type of keyboard. I can […]

Update on the lawyer-bomb across our bow

Yeah, with all what we have going on, the last thing we need is a clueless company firing a lawyer-bomb across our bow. Remember that life isn’t fair, no time is ever a good time, and sh!t happens. It seems that the whole purpose of their … er … communication … was to try to […]

OT: options are known, surgery date is set

In any cancer, it appears the most important thing is to control its growth, arrange for removal, and expedite this process. You don’t want the buggers hanging around for longer than needed. We got our surgery date this past Monday. 1 day after my daughter’s 12th birthday, my wife will undergo the operation. Its the […]

Ok, I gave in and did it

My trusty Dell laptop is about to be retired. Been a year and a half overdue. Doug was working hard trying to sell me the benefits of Mac Air (he has the company’s only unit). He also has the Mac mini on his desk. I need a serious graphics card in the laptop. An NVidia […]

[UPDATED with more info] regression in Gluster

Its looking like updates with older versions lying around didn’t make the new versions very happy. Actually made them very unhappy. More technical than this, it appears that a library search path found the older libs first, and they didn’t mesh well with the newer libs. This was with an rpm -Uvh upgrade at at […]

Moving web code base from Catalyst to Mojolicious

Its a long story. For those who don’t know, Catalyst is a Perl based web framework. So is Mojolicious. The person who started developing Catalyst years ago, left that group, and started Mojolicious later on. I like many things about Catalyst. Like other MVC frameworks, it lets you divide up your logic between controllers (the […]

Monitoring tools

We have a collection of tools that we use for various monitoring. Some are the classical standards (iostat, vmstat, …), the somewhat more heavyweight (collectl, dstat), the simple (not in a bad way) graphical tools (munin, ganglia, …). We’ve found tools like Zabbix do a good job of killing some machines, as there are often […]
