This is the host I’ve been talking about. Adding this entry to /boot/loader.conf will turn off MFI and enable MRSAS instead. hw.mfi.mrsas_enable=”1″ Then you’ll see expected device names for drives, such as da0 instead of mfisyspd0. This will be done later. The HBA installed in this host is supported by the FreeBSD mrsas driver. The host has the Invader/Fury 12Gb/s MR controller installed. There will be more drives. These aren’t necessarily the drives […]
R740? What R740? I don’t have an R740. But I do have an R730. Please try that link instead. Thanks to Mr Barrow for pointing out this error.
I brought home three Dell R730 after saving them from ewaste. Two of them have 8x 3.5″ drive bays. One has 8x 2.5″ drive bays, with with for another 8. This is the one I’m considering for use. I have a fourth R730 in the basement, but I don’t know those specifications, and it already has 16 drive bays. I was thinking of replacing my Dell R720 with one of them, but just
I have new hardware available – should I upgrade or not? Read More »
EDIT: I’m updating this post with new information, I’m missing some photos – they are on my other laptop… EDIT: If you get stuck with older firmware which cannot use existing DELL infrastructure, give https://updateyodell.net a try. It helped me leapfrog along the upgrade path. I started reading Updating firmware etc on a Dell R720 – the details were in a Twitter thread. Until recently, that was sufficient. Today, that thead won’t load.

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 the ssh forwarding shown at the bottom of this post. NOTE: I should start monitoring that IP addr

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 be imported using its name or numeric identifier. config: data01 ONLINE mirror-0 ONLINE gpt/S59VNS0N809087J_S00 ONLINE gpt/S59VNJ0N631973D_S01 ONLINE mirror-1

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 won’t go into the details because the reasons why are easily researched. These cards usually arrive in IR

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 the fiber cards I have in the basement. It turns out, they are all the same. I think
This host has been retired. The services were distributed amongst r730-01 and r730-03. This host was often referred to as r720 or r720-01 (after r720-02 appeared on the scene) 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
