New people to meet

Tuesday, January 29th, 2008

A couple of weeks ago I went and took a test for Mensa membership. It was mostly a whim inspired by someone at work that is a member and a discussion with some co-workers.

I have not failed a test in about 15 years, when I first sat for the Amateur Radio technician level test. Working with computers and IT, certification tests are common and even the Red Hat Certified Engineer exam was challenging but I completed it and knew that I had done well. When I left from the Mensa exam, I had not completed anything and had no gauge of how well I did.

I received an offer to join Mensa last Friday, so it looks like I did well enough. There are a number of Special Interest Groups including Amateur Radio and Photography and I was surprised to find no Linux or Open Source Software SIGs. I’m just a regular guy whose would like to meet folks and have interesting conversations. The local members I have met are not pretentious at all and have been altogether enjoyable to visit with.

Welcome to a new day at Revantine.net

Tuesday, January 8th, 2008

The notes here will primarily be technology projects I am working on or occasionally a photography outing. If the information is on Google on the first page, I probably won’t have it here. If the information took half a dozen sites and a weekend to implement, I will memorialize it here so we can both find it.

You can view some of my photography at www.capturinglife.org.

tigger reborn

Saturday, December 15th, 2007

We lost power last Monday (Dec 10) and got power back Thursday (Dec 13). I didn’t shutdown the Xen server does properly and the web server was corrupted. I built a new web server vm and connected the old data drives. Breaking tradition, I named the new server www1 so I could more easily tell the difference between it and tigger (the corrupt web server).

Another day

Monday, September 10th, 2007

I haven’t updated the journal in a while, but I’ve add some information to ShellAccounts.

I RMA’d the failed hard drive with Seagate. I shipped the failed drive on Friday. Monday was a holiday and I received the replacement on Thursday. Well Friday because they required a signature. That is a really good turn around time. They sent a 500G ES drive to replace the 320G ES.

I still remember RMA’ing a Toshiba notebook drive and it taking 30 days for them to decide they didn’t have a repair and only shipping me another drive after I called to prod them.

I put the 750G in my workstation and moved the swap to it. That alone improved my frames per second by about 8 while I am in Shatt on World of Warcraft.

Oklahoma Bargains finished moving and opened at their new location. I bought 3 hard drives during the moving sale at a great price. One of the used notebook drives manifested a failure during the Windows XP Home install. My wife took it over there on Saturday and Rob is going to take care of us. He sells a lot of off lease and discontinued equipment and it is a great place to get a machine about 1GHz to play with Linux. Sign-up on the low traffic mailing list for the best weekend prices sent at the end of each week.

Another one bites the dust

Saturday, August 25th, 2007

I had another UPS battery die on Friday. This time it had a larger impact – it was one of the cheaper workstation UPS and was powering the core switch, router and bridge (internet). So everything went black for a short time. What was worse is that several batteries that were working on the rack appear to have been at the end of their life and so I had to try three or four before finding a working UPS. And it still need new batteries too. :P

Moving the gallery
I moved the gallery at http://www.capturinglife.org from the stand alone box back to the web server now that the web server has a lot of storage. That let me power down another box. Less power, less heat, less noise…

Speaking of noise, I put the french door back on my office as well so the 1U is not filling the house with the buzz of fans.

All I need to do to migrate gallery was to backup the database, copy the files over and then restore the database. I used phpMyAdmin to backup and restore, and upgraded phpMyAdmin while I was at it. One minor path change in config.inc.php and a dns update and it was up and going.

Xen block process
I ran in to a problem with a vm last week where processes named “block” spawned many process, the host machine was non-responsive and the vms had odd problems. I restarted and it cleared up, but I will need to monitor for that kind of behavior.

A new hard drive for owl

Thursday, August 16th, 2007

I ordered a new hard drive from ZipZoomFly.com last week and it arrived Monday evening. I powered the server down and put the drive in that night about midnight since I doubt anyone was using it at that time. I should find out if it is possible to hot swap the SATA drives in that Tyan chassis. I was not sure enough of it to try.

Migrated the web server to xen

Sunday, August 12th, 2007

Early in the morning…
I started migrating tigger tonight. tigger vm It is moving about 8G of data and so I am going to sleep and will pickup tomorrow. This has definately been smoother with all the things I have learned from the first two. It will also be the last full server migration as everything remaining needs to be moved as services rather than servers.

And later…
tigger, the web server went the smoothest of all the servers. I am really pleased with the process. The only hitch I had was that while rotating the filesystem /tmp permissions changed. It caused an error but was easy to fix.

A bad egg

Thursday, August 9th, 2007

I made a lot of progress tonight. The problems with amavis-new were /tmp permissions that were wrong, and missing nodes in /dev. The missing /dev nodes led me to the root cause of the missing urandom and so I fixed a deeper problem. In the progress I believe I have completed the migration of the mail server, gopher.

I am more than fed-up with NewEgg.com. When I setup owl, the xen server, I bought 9 hard drives over a period of a month.
I bought 2 and I bought another 4 shortly after. Because of a smashed AMD Opteron CPU I did not immediately unpack the first 2.
First 2, 1 bad.
Next 4, 2 bad.
NewEgg had me ship them back seperately on 2 RMA numbers so it cost about $16 in shipping.
Because they do not cross ship and I am now 2 weeks behind, I returned those 3 for a refund and ordered 3 more. This makes the total 9 now.
When the 3 replacements arrived, one of them was DOA. That brings the score to 4 out of 9 dead on arrival. I should also mention the first batch looked like they were dropped before leaving NewEgg – the case was flanged.

NewEgg has no way to file a complaint about product handling. Even the employee I spoke with did not know how to spell Seagate (C gate as he put it). Seagate took care of the last one; they replaced it with a 750G SATA drive.

Avoid NewEgg hard drives. They do not handle them properly.

Bad admin, no cookie

Monday, August 6th, 2007

So last night I was building gopher and when I rsync’d the /etc directory I wasn’t in the vm, I was in the host OS. So tonight I reloaded the host OS :P

The only upside is that I know the instructions work and what options to select.

kanga and gopher are moved

Sunday, August 5th, 2007

I finished the migration of kanga and documented the steps well enough I should be able to duplicate the process kanga vm. The notes about the MySQL migration were more complicated so I put them in a seperate document. kanga: Migrating MySQL.

Now that I have a process I will test it on another server and see how smoothly it goes.

I got started on the mail virtual server, Gopher: gopher vm.
