Adding in a stand-by spare drive for ZFS on FreeBSD
This is a follow up to Adding in a hot-spare for zfs on FreeBSD from two months ago. The replacement for the returned drive has arrived and after sitting for many weeks on my coffee table, it is installed in r730-03. Here it is, as found in /var/log/messages – this host is a Dell R730 which has drive cages allowing me to insert the drive without powering off the host. Jun 30 16:17:15

Making sure I remove the correct drive
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.

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

Dell R730 – moving disks from front drive bay to PCI slots in r730-03
I’ve been seeing these types of errors for about 4 weeks now. I ordered a replacement drive. When it arrived, I realized I had no free drive bays. When a drive is still functional, I prefer to leave it in the host to retain zpool integrity. Instead, I will add the new drive in, run the zpool replace command, and when completed, remove the faulty drive. I decided to order more Icy Dock

Using powerd++ to reduce power consumption on a Dell R730
Yesterday, I changed CPUs in my main server. That server builds packages, is the database server for dev, test, and stage freshports, amongst other things. It is a generalized server. In this post: FreeBSD 14.0 powerdxx-0.4.4_1 Dell R730 2x E5-2699 v3 CPUs As folks started reading my tweets, crest pointed out that powerd++ may help. SPKaniu also mentioned cycling down.

Spreading thermal paste – replacing Dell R730 CPUs
On Sunday, I replaced the CPUs in r730-01 with something quite a bit more powerful. I have been thinking about doing this since before this September blog post: Can I really swap CPU and RAM between my Dell R730 servers? The answer was: Yes, I can.
