banstyle.nuxx.net: It’s Back

The display on the VGA output of my new server, banstyle.nuxx.net, after it went down hard at ~01:30 EDT on 05-Sep-2008.

My server, banstyle.nuxx.net is back. In case you didn’t see the LiveJournal post I made about the server being down, know that it went down about 01:30 EDT this morning and didn’t come back up over night. The symptoms were that the machine had an active link to the switch, but the arp cache was aging and the box was generally unreachable and unresponsive. Here’s a Cacti graph showing the outage.

At lunch I drove down to the colo facility, was escorted down to the room, and first noticed that the box was powered up, the network activity LED was blinking, but the disk controller LED was dark. Plugging in a monitor I saw that blinky colored bars overlaid on the normal console, looking like a hardware problem. Perhaps something with the video controller.

The box was rebooted, and as a precaution I went into the BIOS and disabled the bits which redirect video output (text mode only, of course) to the serial port, essentially allowing the whole box to be managed from a terminal. I figure that maybe, possibly, somehow this contributed. After that, I booted the OS back up, did an initial check to be sure everything was okay, started the backed up mail on the old box flushing, and left. Things were a bit slow at first while fsck ran in the background and the mail filtered through, but after that everything seemed good.

So, to be honest, I don’t really know what went wrong. The server is working well again, I guess I’ll just have to keep a close eye on for a while. This is particularly frustrating because it’d been working great for the last four months while I had it at home. If there are any more problems, please bear with me…

For reference, here’s the stuff in /var/log/messages showing that there was nothing between the events noted in last night’s post about SMTP-AUTH and the reboot this morning:
