This post talks about how I reduced the power consumption on my Dell R720 by adjusting the configuration settings. In this post: Dell R720 Sources I found Taming a 12th gen Dell PowerEdge when I was researching data cables for the SAS card I was going to use. For the record, the cables referred to in that post are wrong for what I used. I bought a pair of DELL POWEREDGE R520 R530 […]
Dell R720 – reducing power consumption Read More »
I like to build systems that boot using drives directly connected to the M/B. No HBA, no SATA cards, etc. I like the simplicity involved. Sometimes that target is hard to achieve. The first step to configuring the R720 was upgrading the firmware. I spent time on hardware selection, including power and data sources. I also spent time looking at NVMe booting, but abandoned that idea. Earlier this week, enough hardware had arrived

This post has been replaced by a new one. This replaces a previous post. I’ve been given a Dell PowerEdge 720. It contains 8 x 400GB SSDs and one 80GB SSD for the OS. I’ve added in a SAS 9207-8i card, as mentioned previously. The zpool: The filesystems: And dmesg:
This post has been replaced by a new one. I’ve been given a Dell PowerEdge 720. It contains 8 x 400GB SSDs. I’ve added in a SAS 9207-8i card, as mentioned yesterday. FreeBSD is not installed. I booted the system up via mfsBSD and had a look at dmesg output.
I have obtained a Dell R720 containing 10 x 400GB SSDs. The drives are connected to a RAID controller (H710P) which cannot do JBOD / IT mode. This means the drives are effectively hidden from ZFS, which is never good.

See also: Updating firmware etc on a Dell R730 I started writing this blog about a month ago. Last night, I did the firmware upgrade completely forgetting I had this draft post in my blog. Instead of reading this, I wound up doing something very similar, and pretty much lived tweeted it. After upgrading the IDRAC to the latest, I then went into the LifeCycle Controller and upgraded nearly all the things. However,

On supernews a drive acted up over night. The main purpose of this post is for me to record the information. You might not find much useful here. The host is running FreeBSD 12 and is a FreshPorts development box. I saw this error in the logs: smart emailed me because I set that up some time ago. The email looked like this: This message was generated by the smartd daemon running on:

As previously mentioned, zuul has new drives. It is now time to replace the existing drives with the new drives. I will do this one at a time. Replace. Wait for resilver. At no time will the mirror be degraded (as would be the case if we removed a drive and mirrored). In this approach, we will mirror one of the drives to a new drive, and zfs will automatically remove the old

I have two new drives for zuul. I’ll start adding them into the zpool soon. For now, here is the smarctl output for the new drives. I’ll start some tests on them soon. By new, I mean new to this host. The drives have 17,000 hours on them.

This covers the facts regarding the list of things to do on Server Build Saturday. The slocum – the new hardware changes occurred on 2 February 2019, with the help of a guy I’ve known since my early days in PA. jb33z did the heavy lifting, both of the chassis and of the HDD. He moved all the HDD from the old server to the new server. I did the SSDs, which were
