Playing around with a ‘failing’ drive

Leave a Comment / Disks, hardware / By /

In zpool replace, you can read about a drive which was giving errors and which I replaced. At present, that drive is [still] giving these errors, but it not part of any spool.

Adding another pair of drives to a zpool mirror on FreeBSD

1 Comment / DELL, Disks, FreeBSD, General, hardware, Open Source, R730 / By /

Today, I’m ready to adding two recently obtained 12T spinning disks to r730-03. This host is the work-horse which houses all the main backups and database regression testing. It also hosts my newly-created but not yet-functional graylog jail. I will be following a previous post about adding drives because I don’t want to remember these things. They occur infrequently enough that documenting it is a good idea. In this post: FreeBSD 14 The

r720-02

I’ve been given a Dell PowerEdge 720, which will be known as r720-02. It sits in a datacenter in New York, New York, and acts as a FreshPorts node. For example, if you’ve ever accessed dev, test, or stage [.freshports.org], then you’ve accessed this host. Partitions zpools The zpools: Filesystems The filesystems: dmesg And dmesg:

Clearing out multiple drives – while watching Band of Brothers

Leave a Comment / Disks, FreeBSD, hardware, Open Source / By /

The accomplished reader will first ask, how is this post any different from Clearing-out multiple drives concurrently – while Watching Fargo Season 5? Well, first, it’s a different server. This one is r720-01. Second, I’m watching Band of Brothers, which is completely different. However, the approach is the same: Boot the host using an mfsBSD thumb drive ssh in as root wipe the drives watch Band of Brothers profit What’s not to like?

Dan adds 2 x 12TB HDD into r730-03

Leave a Comment / Disks, hardware, smartctl / By /

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

Leave a Comment / Disks, FreeBSD, hardware, Open Source / By /

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 It has been replaced by r730-03.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

Leave a Comment / Disks, FreeBSD, hardware, nvme, R730, ZFS / By /

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

Leave a Comment / Disks, File Systems, hardware, R730, ZFS / By /

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?

Leave a Comment / DELL, Disks, hardware, R730 / By /

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
