Today is the day. Today I move a zpool from an R710 into an R720. The goal: all services on that zpool start running on the new host. Fortunately, that zpool is dedicated to jails, more or less. I have done some planning about this, including moving a poudriere on the R710 into a jail. […]

This post is all about moving poudriere from the host into a jail, but you could probably use it for creating a new jail and running poudriere in it. NOTE: If you’re looking for a jail configuration for poudriere, please refer to Configuration for running poudriere in a jail on FreeBSD 14 – it contains

Today the drive caddies arrived for the R720. I refer to the services provided by the R710, not the server itself. I will list those services later and outline how I want to move them. I could do all this over this coming weekend but I have already allocated that time to some errands I

I planned to create a zroot mirror when I installed FreeBSD on the R720 but the supplier shipped only one of the two purchased SSDs. Today the second drive arrived. Let’s create a zroot mirror. In this post: FreeBSD 12 man 8 zpool Posts I looked at: creating a mirrored ZFS Pool out of a

Over the years, I have learned not to rely on hostnames for important services. Hosts go away, new ones come in. I want to rely on, what I refer to as, service names. For example, instead of relying on a hostname for my ntp server, I have: $ host time time.int.unixathome.org has address 10.55.0.1 This

This post talks about how I reduced the power consumption on my Dell R720 by adjusting the configuration settings. In this post: Dell R720 Sources I found Taming a 12th gen Dell PowerEdge when I was researching data cables for the SAS card I was going to use. For the record, the cables referred to

I like to build systems that boot using drives directly connected to the M/B. No HBA, no SATA cards, etc. I like the simplicity involved. Sometimes that target is hard to achieve. The first step to configuring the R720 was upgrading the firmware. I spent time on hardware selection, including power and data sources. I

This post has been replaced by a new one. This replaces a previous post. I’ve been given a Dell PowerEdge 720. It contains 8 x 400GB SSDs and one 80GB SSD for the OS. I’ve added in a SAS 9207-8i card, as mentioned previously. The zpool: The filesystems: And dmesg:
This post has been replaced by a new one. I’ve been given a Dell PowerEdge 720. It contains 8 x 400GB SSDs. I’ve added in a SAS 9207-8i card, as mentioned yesterday. FreeBSD is not installed. I booted the system up via mfsBSD and had a look at dmesg output.
