This is the Dell R7425 host known as r7425-01. At idle, despite holding 12 x 12TB HDD, this chassis is pulling about 300-350 watts. gpart zpool list zpool status zfs list dmesg sesutil show [22:28 r7425-01 dvl ~] % sudo sesutil show ses0: ; ID: 500056b345a433ff Desc Dev Model Ident Size/Status Drive Slot 0 da0 ATA HGST HUH721212AL 8CGSV9DG Unknown Drive Slot 1 da1 ATA HGST HUH721212AL 8CGSXG6G Unknown Drive Slot 2 da2 […]
This post has been replaced by a newer post. This is the Dell R730 host known as r730-01. For reference, the previous post on this server is still available. This host has undergone major storage changes over the past few weeks. This post will reflect those changes This is my primary developer server in my basement. gpart zpool list zpool status zfs list dmesg sesutil show [18:41 r730-01 dvl ~] % sudo sesutil

This post documents the drive locations for zpools within r730-01. It will be replaced from time to time with a new post. To the left of a device is an indication of the drive physical location. Unused devices Unused drives/slots: Slots 12 & 13 each contain a 4TB SSD. Slots 14 and 15 are empty. Those drive cages are on the workbench and each hold a 2TB SSD. There are also NVMe devices
In this post, I’m moving my zroot zpool from larger devices to smaller devices. Why? Well, the smaller devices happen to attach directly to the main board of my server, albeit with some slight modification to a fan cowl. There have been several recent posts regarding this topic. I tried a different zpool approach, where I added new devices to the zpool and removed the old devices. That worked. It wasn’t ideal for

These are some notes I want to keep handy. They will help me switch back and forth between UEFI and BIOS booting. In this post: FreeBSD 14.1 Dell R730 To move from BIOS boot to UEFI boot System BIOS | Boot Settings: Boot Mode = UEFI System BIOS | System Settings | Device Settings | PERC: Select Boot Device = None Then you have to wait for it to boot, query devices, the

This post is part of a series of storage-related posts. The goal: move the zroot of r730-01 to smaller drives. NOTE: This approach failed. Investigations continue, however this post is not something you should try. This other successful post might be useful, although I still don’t know why the attempt in this post fails. Earlier today, as the first step in my proof-of-concept, I moved the zroot of r730-04 from 2x SATADOM device

Today, using FreeBSD 14.3, I’m going to test booting from a drive which is a mirror of the boot drives.

It is a rainy Wednesday morning and I’m drinking a cappuccino in my favorite cafe. A five minute walk from here, in the basement of an 1890 Victorian twin house, sits r730-04. Last weekend, I configured it to boot from two SATADOM drives. Today, I’ll move that zpool to a pair of larger drives. I’ve done that move before and it is a common procedure for increasing zpool capacity. Later today, I’ll move

A recent goal is to increase the available storage space in my main development server in the basement. To that end, two recent posts: r730-01: the drive replacement plan r730-01: storage plan The SATADOM devices I purchased are meant to be plugged directly into the M/B of the server. This approach will free up two PCIe slots which were hosting 2x 2.5″ SSDs in a hot-swap adaptor (the post mentions a Dell R720;
