HEADS UP: this is still under review. Until this notice is removed, I recommend not using this. I have a Dell R720 at an ISP. The iDRAC connection is filtered, by the ISP, and is accessible only from a small number of IP addresses. Sure, this talks about a web proxy. It works. So does …

I have these boot drives, I want to copy them to another. They both happen to be zroot and bootable. I booted from mfsBSD and imported both new and old zroot, using the pool ID shown by zpool import -N. root@mfsbsd:~ # zpool import -N pool: data01 id: 2668514456528412656 state: ONLINE action: The pool can …
Dell PowerEdge Servers are common in #homelab use. The hardware gets sold after it goes out of warranty and they get dumped. Most of the disk cards in these servers come flashed for use with RAID and RAID only. Never use a RAID card with ZFS. Always give ZFS direct access to the drives. I …

Sometimes I’ll be thinking about the hardware I have which is not in use. I’ll know it exists, but not the details. I’ll be in the wrong part of the house to have a quick look, or I might be nowhere near the house when the topic comes up. This post fixes that. These are …
This replaces a previous post. I’ve been given a Dell PowerEdge 720. It contains: 6 x 400GB SAS SSDs – data01 zpool 2 x 100GB SAS SSDs – unused – I think this is da0 and da1 2 x 80GB SATA SSDs – zroot zpool 4 x 500GB SATA SSDs – tank_fast zpool 1 x …

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 …
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 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 …
