I recently migrated a bunch of jails from one server to another. Today I attached the Dell TL4000 tape library. A jail on this server copied Bacula backups from disk to tape. In this post: FreeBSD 12.0 Bacula 9.4.3 Dell R720 Investigation As anticipated, I needed to update the server configuration to cope with changed […]

I noticed this the other day, and thought it was interesting. When the jailed property is set on a ZFS fileset, it affects the mountpoint within the jail. If your jail uses allow.mount.zfs (known as allow_mount_zfs when using iocage), the mountpoints become relative to the jail. For example, in my poudriere jail, this is what

In this post, I’m not exporting an iocage jail to another host. I am moving the entire iocage instance to another host. This is accomplished by doing a zfs export on the zpool, moving the drives to a new system, and doing a zfs import. The drive migration is covered in a previous post. In

I have scripts for monitoring vulns in FreeBSD jails. They use third-party scripts. All I wrote was the Nagios part of the solution. I was preparing slides for my Why I prefer thick jails over thin jails talk at EuroBSDCon 2019. There is still time to register and attend. I was explaining my scripts and

I have been using ezjail since at least 2008 (see earlier blog post). A few years ago, I started deploying iocage on new servers. About three months ago, I starting converting systems from ezjail to iocage. When I converted my first system, I found that the existing documentation for conversion was incomplete. Specifically, symlinks were

I use bind (Berkeley Internet Name Domain) as my DNS server. I am currently running bind 9.11.5P1 on FreeBSD 11.2-RELEASE-p8 in a jail, with iocage as my jail manager. The OS, jail, and jail manager should play no part in how this works. I have been collecting statistics from bind for some time. I have

Sometimes you just need that old version. So I installed it. FreeBSD 9.3 Sorry, but this article is light. I stopped taking notes after a bit…. We created a VM via VMware, put FreeBSD 11.1 on it, over ZFS. Then install iocage. This is what it looked like: What did it just install? This: $

FreeBSD 10.3 & PostgreSQL 9.4 on the old server, and FreeBSD 11.1 & PostgreSQL 9.6 on the new server. As part of the move from the old FreshPorts server (photos) to the new FreshPorts server, I’ll need to dump the database and copy it over. What? No zfs send? There is no ZFS on the

Yesterday, I upgraded a DigitalOcean droplet from FreeBSD 10.3 to FreeBSD 11.1 just before I headed to work. I’ve done such upgrades several times before. They all went well. This one did not. Several issues cascaded to prevent me from completely this task in a timely manner. Let me describe the events as they unfolded.

Following on from my post about excluding the base OS with a Bacula FileSet, I decided to exclude some more. The starting point Here are the baselines: What else will I exclude? I decided to exclude the following as well: Adding iocage support Along the way, I extended the Exclude to work on server using
