I've been playing with computers since I read an Elementary Electronics magazine way back in the 1970s. I started contributing to open source projects in 1998. After that, I gradually moved from being a software developer to being a systems administrator.

ntp wasn’t running but Nagios didn’t notice

3 Comments / Nagios, Network monitoring / By /

Earlier today, I noticed the following output from a Bacula job: 24-Sep 14:14 bacula-dir JobId 38548: Start Backup JobId 38548, Job=latens_home.2010-09-24_14.12.38_31 24-Sep 14:14 bacula-dir JobId 38548: Using Device “MegaFile-latens” 24-Sep 14:09 latens-fd JobId 38548: DIR and FD clocks differ by -307 seconds, FD automatically compensating. That’s 5 minutes. It shouldn’t be varying by that much. So I started ntp. That’s when I noticed it was not being started by /etc/rc.conf. But I thought […]

Rebate!

Leave a Comment / hardware / By /

Back in Feburary, I ordered a 720W PSU for $150. There was a $60 rebate with it. When the PSU arrived, I promptly filled out the form and put it in an envelope for mailing. Except, I didn’t mail it. I found that envelope a few weeks ago. What the hell. I mailed it. It was already stamped etc. Today I got a $60 VISA debate card. Win. Interestingly enough, I originally bought

Sending out a URL for password reset

Leave a Comment / FreshPorts, Open Source, PostgreSQL / By / /

Quite some time ago, FreshPorts and The FreeBSD Diary both moved from clear text passwords to password hashes. As such, you are no longer able to recover your password. You had to email me. This is extra work for everyone. Let us automate this. The first, step, is a table: create table user_password_reset( user_id int not null, date_requested timestamp with time zone default (‘now’::text)::timestamp(6) with time zone, ip_address inet not null, token text

It seems the RAID issues mentioned in recent posts have been resolved. On Friday, I upgraded the firmware on the controller and rebooted. 5 days later, the status is still OK: $ sudo /usr/local/sbin/tw_cli info c0 u0 Password: Unit UnitType Status %RCmpl %V/I/M Port Stripe Size(GB) ———————————————————————— u0 RAID-10 OK – – – 64K 195.548 u0-0 RAID-1 OK – – – – – u0-0-0 DISK OK – – p0 – 65.1826 u0-0-1 DISK

More RAID oddness

After running the 3Ware diagnostic script, the status of the array went to OK. A short time later, it reverted to this $ sudo /usr/local/sbin/tw_cli info c0 u0 Unit UnitType Status %RCmpl %V/I/M Port Stripe Size(GB) ———————————————————————— u0 RAID-0 OK – – – 64K 195.548 u0-0 UNKNOWN UNKNOWN – – p0 – 104.314 u0/v0 Volume – – – – – 195.548 But this differs from the web output (image) which is rather similar

FreeBSD 7.3 – you don’t want 16 CPUs

Leave a Comment / FreeBSD / By /

Oh… Apparently this afflicted 7.3-RELEASE for a short while, then was corrected in 7.3-STABLE. So I’m not sure what problem I was encountering below. The consensus now is I was hitting MAXCPU. But I should have hit that on 7.2. I upgraded a VM to FreeBSD 7.3 from 7.2 and now it won’t boot. It stops probing at MDT: Found CPU APIC ID 15 ACPI ID 15: disabled. Tried booting in single user,

Dual head RADEONHD – screen blanking

Leave a Comment / xorg / By /

I recently upgraded xorg on my workstation at the office. Immediately I started seeing problems with one of the monitors. It would go empty/blank/black for three seconds, then resume normal operation. Then it would go blank again when I interacted with the screen. In short, that one monitor was completely useless. Swapping cables on the dual head video card moved the problem to the other monitor. All software was the latest version: xorg
