Dan adds 2 x 12TB HDD into r730-03

I know, I know. You can hardly contain your excitement as you read about my exploits. In this post, I add the drives into the host and run some simple tests. As in recent posts about 12T drives, these drives are not new. They are used drives. A later post will deal with the commands which add these new drives into an existing zpool. These drives came from serverpartdeals.com. They are used and […]

Clearing-out multiple drives concurrently – while Watching Fargo Season 5

It is time to let the knew server go. It has gone through multiple upgrades, new drives, new boards, and new chassis. It has been replaced by r730-03. Before I let it go, I want to clear off the drives. By that I mean: I did this by booting the host using mfBSD (a lovely USB-bootable version of FreeBSD). I then ssh‘d in as root (one of the few situations when ssh as

Moving 4x storage devices into a new home

Yesterday I did some scavenging of some servers which I’m going to dispose of. I managed to put together 4 x 1TB storage devices: 2 x NVMe sticks and 2 x SSDs. I also pulled a riser card from an R730 and relocated it to another host. The NVMe sticks are mounted on these PCIe cards, which I do not regret buying. They came with full height and low-profile brackets. More to the

Preparing a server for sale – Supermicro 846 – 10 x 5TB HDD

FYI: This server has since gone to a new home. After powering off the server about 8 months ago, I took the first steps to selling it. I opened it up and took out 2x NVMe sticks (1TB each, ZFS mirrored, giving a 930G zpool) INTEL fiber NIC (Intel X540-AT2) I’ll be keeping those items. I also took an inventory of the drives still in the system: 10 x 5TB drives – all

How much noise will I lose when I power off this server?

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 realized the noise I heard was the ceiling fan. After switching that off, I could no longer hear

They’re here! 2x (new-to-me 12TB HDD)

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. These drives came from serverpartdeals.com. They are used and re-certified. In this post: FreeBSD 13.2-RELEASE-p2 Dell R730 In they go This

Testing two 12TB drives in a Dell R730 on FreeBSD

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 Direct Access SPC-4 SCSI device da2: Serial Number 8CJVT8YE da2: 150.000MB/s transfers da2: 11444224MB (23437770752 512 byte sectors)

Dan makes another zpool

I spent my lunch, and most of my mortgage payment, on 4 x 4TB Blue 4TB SSD 3D NAND (WDS400T2B0A).

Maybe I need another zpool

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/. I thought I had the space calculations done right. Now I think I’m wrong.I’m already at 73% on

stressdisk

This was written a few weeks ago and I just noticed today that it had not been published. Following on from I bought a new nvme drive – or did I?, I ran stressdisk on it.
