esxcfg-nics & esxcfg-vswitch

by

One of my ESX Servers’ management NICs died today, right as I was to start upgrading to ESX 3.0.2. I don’t have the admin NICs in a redundant configuration yet, and it’s fairly inconvenient to lose management capabilities as you’re about to need VMotion. Luckily[0] I had an extra, unused NIC, esxcfg-nics, and esxcfg-vswitch. With these commands you can display and alter the settings for the NICs and virtual switches from the console. So, you find out what you have available with “esxcfg-nics -l” Then you look at the relationships between the virtual switches and the NICs using “esxcfg-vswitch -l” Since vmnic3 isn’t being used I ran: esxcfg-vswitch –unlink=vmnic0 vSwitch0 esxcfg-vswitch –link=vmnic3 vSwitch0 And back up it came.

VMworld 2007 Here I Come

by

I finally got registered for VMworld 2007 today. I am looking forward to it. It does look like I’ll have to sneak into a lab or two on the 10th, though (engage my l33t stealth ninja skillz). Late registration does take a toll that way. I’ll be out there from September 8th until the 15th. Anybody else going? Want to go out one night and have a beer? I want to hit Jack’s Cannery Bar at least once while I’m out there, and with 100 beers on tap I think we could find something we like… 🙂 (there’s always SFBC, too)

I Hate "k"

by

Email and instant messages that consist solely of the letter “k” drive me nuts. Why? A) You couldn’t be bothered to type “Okay” or even “OK” in full. It’s hard, I know, especially with a full keyboard at your disposal. B) You added no value to the conversation. Why even send the message? It is different if I was asking your opinion about something, where “OK” might be an acceptable and desirable answer. I wasn’t, though. C) You made me open my IM client again, to read ‘k’. I wish I could build a filter in Psi so that any messages that consisted of the phrases “k” or “thanks” or “np” could be silently acknowledged. D) This makes me think …

How To Get The Open Apple Back On The Mac Keyboard

by

The new Macintosh keyboards are missing the Open Apple. There are various movements to save the Open Apple, including a petition to have Apple put it back. Given Apple’s history of taking design advice from the masses I suggest taking matters into your own hands: Order a new keyboard from Apple. Order a pack of Sharpie Metallic Markers. Order an X-Acto knife. Print out an image of the Open Apple. You’re resourceful, you can find one yourself. Do this on card stock. Use the X-Acto knife and cut the image out to form a stencil. Put the stencil on your new keyboard, and using your new, cool Sharpies trace around the edge. Keep it uniform so it looks good. If …

Airport Security

by

Matt Mullenweg posted that he discovered a 2 inch knife in his carry-on luggage. That is, after he’s cleared security a number of times. I know the feeling. I had a screwdriver in my carry-on backpack after flying at least three full round trips last year. One of those interchangeable bit types, with the removable shaft in the middle. Didn’t mean to have it, but you’d think that it would have been caught. Every time I stand in the hour-long checkpoint line, shoes in hand, I think of that screwdriver, and how ridiculous this all really is.

Use dir_index for your new ext3 filesystems

by

Directories in ext2 and ext3 used to be simple linked lists. These had scalability problems. When you put a lot of files in a directory programs like ‘ls’ took non-linear (O^2) amounts of time to complete. To resolve this the ext3 folks added a new directory indexing feature, which replaces the linked lists with an “HTree.” I’d never heard of an HTree before, either, and Daniel Phillips, the inventor, explains in a paper presented at USENIX ALS 2001: …I went on to discard the BTree approach, and invented a new type of indexing structure whose characteristics lie somewhere between those of a tree and a hash table. Since I was unable to find anything similar mentioned in the literature I …
