I’m sitting in the The Warden – FreeBSD and Linux Jail Management talk at EuroBSDCon 2012. He has mentioned two things, so far, that give me ideas. Evil ideas. Put each jail in a different ZFS data set – this may be useful for my jails running Bacula regression testing Schedule cron jobs to do snapshots on a regular basis – useful for snapshots, which I’m not really using at all And he’s

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 because of the power cycle. The scrub was a weekly automatic operation which started some hours before my

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 host. There is was. I’ll show only a small part of the ifconfig output: $ ifconfig inet

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 cause some confusion, here they are: root ntpd 63822 25 udp4 10.35.0.100:123 *:* Warning: Some services already seem

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 the base OS: ada8 ada9 Seven are active in an array: ada0 ada2 ada3 ada4 ada5 ada6 ada07

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.
