Destroying some unneeded ZFS snapshots
Last night, I found that I had a number of unused ZFS snapshots. I decided to destroy some of them. The first destroy locked up the system. Nagios reported everything was dead. I remotely power cycled the system. After it came back, I noticed that a scrub was in progress. This had not been initiated

After recent efforts to get old jails running on a new server, I tried to upgrade some ports today. I failed. portupgrade was erroring out and reporting: protocol not supported A simple fetch http://www.google.com/ was giving me fetch: transfer timed out I tried portaudit -Fa. Nothing. fetch: transfer timed out I checked ifconfig on the

jail: execv: /bin/sh: No such file or directory
Recently, I was moving some jails from one server to another. First, I created the jail using the -x switch, which indicates the jail already exists, don’t create it, just add entries for it: # ezjail-admin create -f bacula -x mysql41.example.org 10.35.0.100 Warning: Some services already seem to be listening on IP 10.35.0.100 This may

ZFS details – just in case
I use a ZFS array for backups. The data is first copied to this array, and later copied to tape. This post contains some information which might be useful should I need to replace one of the drives in the array. We have 10 HDD in this system. Two are used in a gmirror for

AT&T tried to kill BSD
I cannot claim this. Will Backman said: Thing I think about while driving: BSD. AT&T tries to kill BSD. Steve Jobs uses BSD to save Apple. Apple makes the iPhone. iPhone is tied to AT&T. iPhone activations save AT&T from the recession. BSD saved AT&T.

Sending out a URL for password reset
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

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
FreeBSD 7.3 – you don’t want 16 CPUs
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

ZFS & gmirror & drive renumbering
I am impressed…. my gmirror array continued to work even after the drives were renamed from da20 and da24 to ada0 and ada1. This happened when I tried out the ahci(4) for my SATA drives. It’s the type of thing I’m striving for soon in my ZFS array. All this started when I wanted to
