Making sure I remove the correct drive

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

Yesterday, I discovered I had removed the wrong drive from a zpool. In this post: FreeBSD 14.2 Today, the zpool replace command has completed. Next, I carefully chose the right drive to pull from the drive bays. Status This is the zpool status, just before it completed: After it completed: I see gpt/SG_ZHZ16KEX is no longer in the zpool. Not trusting myself, I checked this way: [20:33 r730-03 dvl ~] % zpool status […]

Adding in a hot-spare for zfs on FreeBSD

But first, there’s more Right after asking “Anyone running zfsd? Did you do anything in particular to configure it? I just added my first hot-spare to a zpool.”, ivy told me “noooooooo don’t use hot spares!! Keep a cold spare or at least an online device not attached to a pool. otherwise your zpool will randomly decide to attach its hot spare due to a temporary cabling issue or something like that. the

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

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

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
