The new gateway configuration
Today I created the new gateway machine. It is a ZFS-only system with 3x3TB drives in a mirror configuration. The hardware was my old ZFS workhorse, now replaced by something with more storage. I had a moment of panic, thinking this server had just one NIC, but I was wrong. em0 will be the local 1G LAN. re0 will have to be my upstream connection. That’s pretty sad, given it’s only a 10Mb

Using Bacula in a jail
I use FreeBSD. I’ve used it since 1998. For me, it does good stuff, reliably, and predictably. The community is very supportive and helpful. That goes a long way when choosing your open source operating system. Included within FreeBSD, since FreeBSD 4.0 in March 2000, is a great tool for separating out services and to provide a virtualization strategy: jails. Some will argue that jails are not virtualization. I contend that it’s a

Moving Bacula Volumes from one Storage to Another
A few weeks ago, I moved some Bacula Volumes from one Storage Daemon to another. In fact, I was decommissioning the old bacula-sd and creating a new one. I copied all the Volumes over. Backups have been running smoothly ever since. However. Today I tried a restore. It failed. Without any useful diagnostic information. Here is what I have: After thinking for a while, I started to wonder if this was a database

Adding in the new SCSI card
I’ve been building up a new server lately. Now I’m ready to move the tape library from the old host to thew new host. As I opened the new server to insert the existing SCSI card, I discovered that I needed a new SCSI card. It just would not fit. This is the card I was using under FreeBSD 8.4: ahc0: <Adaptec 2944 Ultra SCSI adapter> port 0xa800-0xa8ff mem 0xfb7df000-0xfb7dffff irq 20 at

ezjail-admin: moving a jail between hosts with archive
I’m in the process of moving a system from one server to another. Today, I’m going to try moving a jail using ezjail-admin archive. The two systems I am copying jails between these two systems: source: FreeBSD 8.4-RELEASE destination: FreeBSD 9.1-RELEASE-p4 I really am interested to see if this works. Creating the archive Best practice is to stop the jail. You can archive a running jail, but I content that you will get

sudo: effective uid is not 0, is sudo installed setuid root?
Tonight I created a new jail, and later installed sudo into that jail. Then I tried to run sudo: $ sudo make install clean sudo: effective uid is not 0, is sudo installed setuid root? What? It is setuid: $ ls -l `which sudo` -rwsr-xr-x 1 root wheel 117112 Jul 26 17:08 /usr/local/bin/sudo I had no idea. wxs had the answer: mount points. Here is the problem, as revealed by this command in

Moving zfs datasets / filesystems around
After the zfs send, I had system/foo/bar, but I really just wanted system/bar. How do I fix that? mv(1) was my first guess. I was wrong. What I wanted was zfs(8) rename. Let me explain. After doing my: zfs send storage/compressed/bacula@2013.07.22:06:33 | mbuffer | ssh -t dan@10.5.0.20 ‘zfs receive system/usr/local/bacula/FromKraken’ I quite, correctly, wound up with system/usr/local/bacula/FromKraken, not the system/usr/local/bacula which I wanted. Here’s how I fixed that, but first, I took snapshots,

zfs send | zfs receive; finally finished
Today it finished. That ZFS send I started on Monday finally finished. Recap The original command was: # zfs send storage/compressed/bacula@2013.07.22:06:33 | mbuffer | ssh -t dan@10.5.0.20 ‘zfs receive system/usr/local/bacula/FromKraken’ That’s was the initial send of the filesystem. But more data has been added to it. So I take another snapshot, and send that: Send what’s accumulated since previous send # zfs snapshot storage/compressed/bacula@2013.07.25:08:20 And now I send the incremental stream: # zfs
