Over the years, I have learned not to rely on hostnames for important services. Hosts go away, new ones come in. I want to rely on, what I refer to as, service names. For example, instead of relying on a hostname for my ntp server, I have: $ host time time.int.unixathome.org has address 10.55.0.1 This […]
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 […]
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 […]
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:
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. In this post: FreeBSD 12.0 ZFS Dell R720 SAS 9207-8i This post describes past work […]
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 […]
I have scripts for monitoring vulns in FreeBSD jails. They use third-party scripts. All I wrote was the Nagios part of the solution. I was preparing slides for my Why I prefer thick jails over thin jails talk at EuroBSDCon 2019. There is still time to register and attend. I was explaining my scripts and […]
zi0r suggested I use hooks to accomplish my patches-outside-distfiles question. In this post: FreeBSD 12.0 poudriere 3.3.2 I started reading the documentation and played with the supplied sample files in /usr/local/etc/poudriere.d/hooks. For background, see FreeBSD custom port patches when using poudriere. Eventually I came up with this solution: mkdir during the start phase mount during […]
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 […]
