Another zroot install

I just converted another server from UFS to ZFS. I used this script as my starting point. I dropped to a shell as soon as I booted from the live CD. Then I fetch my script: fetch –no-verify-peer http://bit.ly/1MvhRXH mv 1MvhRXH install.sh I didn’t run the script. I modified it to suite my new conditions. The install files were not available. I put and exit around line 84. Then I ran my script:

zfs send | zfs receive as non-root

In this post, I am using FreeBSD 9.3 but what I do here should have wide application, especially the errors I encounter. I believe in backups. Not just rsync, but multiple copies and in multiple places. RAID is not a backup. rsync is not a backup. The goal of this post is to send a copy of a ZFS filesystem to a remote server. The server in question is already backed up in

Cannot find any appendable volumes – Bacula

A problem arose today which I have never seen before. I do not know what caused it and I do not know precisely how I fixed it. I am using Baclua 7.0.5 on FreeBSD 9.3 I found this email today: This is Bacula asking for more ‘tape’. I say tape, because that is an easy analogy to follow. In effect, the tape library has no tapes to which Bacula can place this backup.

Failure with freebsd-update; how not to upgrade your systems

freebsd-update is a great tool. It reduces my workload. It’s hard to use it wrong, but I have managed to do so. So have other people. Yesterday, three of us encountered the same issue. We did it wrong. We didn’t do it wrong yesterday. We did it wrong months ago, and now it’s come back to haunt us. NOTE if you ever see: Undefined symbol “ssh_explicit_bzero” on a FreeBSD server, you probably have

nullfs mounts in a jail

Just a note for myself.

APC PDU AP7900 – resetting the password

I have three APC PDU AP7900 and I’m about to dispose of one of them. I like to wipe the configuration from equipment prior to disposal. I could not recall the login details for any of my three PDUs. Fortunately, I still had the serial cable required to get into the console. I also had my serial cable for my laptop. Getting hold of one of these cables is important if you are
