Adding two more 12TB drives to the mirror

As mentioned in several previous posts, I’m moving a server from one chassis to another. None of the hardware is coming over. Just the jails and data. These drives came from serverpartdeals.com. They are used and re-certified. Recently, I’ve been trying out two new 12TB drives. I’m looking forward to the reduced noise level, as […]

How much noise will I lose when I power off this server?

This morning I pondered how much will noise reduce when I power off that server? From the comfort of my living room, directly above the rack in the basement, I powered it off. At first, I was disappointed. I could still hear that repetitive whine. After considering powering off one of the other hosts, I

Bacula – copying the latest jobs over from one SD to another

I want to copy the latest backups for each Bacula client over to a new host. I already do this, on an automated basis, for recent backups, primarily to have the same backups in two different places. In this case, I want to do this once. This post might also be a good introduction to

kernel: pid 4900 (conftest), jid 968, uid 65534: exited on signal 11 (core dumped)

I see see these log messages on a regular basis. There is no distinct pattern. Some nights there might be 1, others 2. Today there were three: r730-01 is my main server in the basement. It runs a jail named pkg01, which does my nightly poudriere builds. Those jobs are launched from this crontab: That

Bacula – calculating Maximum Volume Bytes and Maximum Volumes based on historical data

I’ve used Bacula since at least January 2004 (so nearly 20 years). I liked it so much I dropped my deployment-in-motion of another tool (if you search lightly, you can find out which one). I liked it so much, I wrote a PostgreSQL backend for it. This post is not for Bacula novices. This post

Identifying jails and data to migrate from old host to new host

I’m retiring knew and moving the services over to r730-03. I recently added 2 12TB drives to the latter host. In this post, I’ll start the migration process by identifying what data needs to move, from where, and to where. In this post: knew r730-03 FreeBSD 13.2-RELEASE-p2 The data There are the zpools in question:

Changing how I use IP address with FreeBSD’s vnet – so IPv6 works

The vnet (network subsystem virtualization infrastructure) on FreeBSD is both a blessing and a curse. For me, it isn’t working well with IPv6. I’ve hit issues with pf (since solved, I’m sure). It’s a useful feature but can be confusing. It helps to have lots of time to think about it and what you’re doing.

Testing two 12TB drives in a Dell R730 on FreeBSD

I’m ready to downsize. I’m going to replace knew with r730-03. The former has 20 5TB drives. I don’t need all that space now. I’ll settle for 12TB instead. The two new drives arrived today: [23:39 r730-03 dvl ~] % grep da2 /var/run/dmesg.boot da2 at mrsas0 bus 1 scbus1 target 2 lun 0 da2: Fixed
