Can I really swap CPU and RAM between my Dell R730 servers? I wrote about that recently. Sure. It might just work. First, let’s look at the service tags and find out. I have four Dell R730 servers in the basement: r730-01 – main development server – add some RAM from r730-04 and swap in …

I have four Dell R730 servers in the basement: r730-01 – main development server r730-02 – unused r730-03 – main storage server r730-04 – unused So what’s on each one? If you look at each of the links, you’ll find this information on CPU and RAM. The information is collected from /var/run/dmesg.boot, but not presented …
For reference, the previous post on this server is still available. Today I noticed this post is out of date. I like to keep this information around for each host, just in case it’s needed during a rescue mission. This is my primary developer server in my basement. gpart zpool list zpool status zfs list …
This is the Dell R730 host known as R730-03. It replaces an earlier post. gpart zpool list zpool status File systems dmesg sesutil show jls
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. Recently, I’ve been trying out two new 12TB drives. I’m looking forward to the reduced noise level, as well as the reduced power consumption and heat. In this …
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 …

Yesterday, the drive cages arrived. Today, the 2x (new-to-me 12TB HDD) arrived. They are already mounted in their drive cages and installed. Let’s look at them. This post is similar to Testing two 12TB drives to a Dell R730 on FreeBSD. If you want to know most about the tests, see that. In this post: …
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: …

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 …

I might need to create another zpool. Or perhaps move a drives/zpool from one host to another. In this post: FreeBSD 13.1 Background I am combining two hosts (slocum and r720-01) into one new host (r730-01). I have been moving jails from those hosts. I have an ansible playbook for creating new entries in /etc/jail.conf.d/. …
