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 […]

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

Leave a Comment / hardware, R730 / By /

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. Straight out of ports After installing powerd++, I tried running it: [0:31 r730-01

Spreading thermal paste – replacing Dell R730 CPUs

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

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.

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
