Im a senior linux system administrator for a design and interactive agency. I am a hacker and maker and like tinkering with everything from pcb layout and assembly language on 8bit microcontrolers up to architecture issues with large scale networks. Of course such a wide are of intrest means I am not really an expert at anything.

comment LXC Container Networking
Forgot to mention that the host CentOS 6.5 machine is actually a vmware fusion VM on my macbook pro. The network adapter is bridged though and the host gets a IP from the network DHCP not from VMware. I am not trying to do any weird double NAT stuff or anything.

comment Linode Kernel Headers
The include directory on the kernel.org version does not include a .config file. Im not sure if I could just copy the .config which the script looks for from the 3.2.0-61 generic version but at that point Im crossing even more wires. Im aware I could run one of the kernel config tools but I would not know what to select to match what I actually have installed.

For what its worth I did just compile it against the 3.2.0-61-generic headers and it seemed to work. I still would like some confirmation that this is a safe thing to be doing on a production server.

comment Linode Kernel Headers
There is no kernel-devel package in 12.04LTS. To get the headers you normally install linux-headers-$uname -r but this package does not exist for Linode VPS's since linode uses its own custom kernels. Presumably because they use PV and need custom kernels. I can install linux-headers-generic which installs 3.2.0-61-generic but the Linode kernel is 3.13.7 on this particular server. I was not sure if the API changed at all between these versions and if it was safe to point the compile process at the 3.2.0-61-generic folder or not.

comment VMware ESXi - Fiber Channel Configuration
The ubuntu test was a bit of a red herring. In retrospect I forgot to check if the QLogic card had proper drivers installed. I just checked if disks showed up. The fibrechannel card in the old server has drivers built into the default kernel but that does not mean the QLogic would. So ignore that bit.

I would consider getting a switch and using Fibre Channel. I inherited the current solution. But right now I just spent $6K on a new server so I would like to avoid additional costs.

comment VMware ESXi - Fiber Channel Configuration
I am going to have to wait until after work tomorrow to get another window where I can test this since the disk array needs to be live on the old server during business hours until I get it working on the new server. But then ill have all weekend.

comment VMware ESXi - Fiber Channel Configuration
I am using in a DAS type configuration. Is using the term fibre channel here wrong even though its using a fiber interconnect? Does ESXi support a DAS configuration over a fibre interconnect without a switch? The manual suggests the port be setup as N-Port if there is no switch. In my screenshots its set to NL-Port and working just fine on the old server. The new server is NA. It appears to be auto negotiating these settings. Perhaps I need to manually set it to N-Port. I did rescan the adapter a few times.
