When the time comes to replace a drive, it is very nice to know which drives is missing. I created this drive map to help me figure out which drive disappeared. I created this drive-bay map using a combination of: zpool status sesutil map lsblk camcontrol /var/run/dmesg.boot I have not included /var/run/dmesg.boot here. If you […]

This post has been replaced by a new one. For reference, the previous post on this server is still available. FYI, this server is named after Joshua Slocum, who was the first person to sail single-handedly around the world. This server was upgraded on Feb 2 2019. Only the storage persisted. Everything else was upgraded.
When I set up the R720 with internal SSDs, I used a SATA power splitter, a Y-shaped cable. Today I replaced it because of a known fire-hazard. I received an email from a reader urging me to replace it and supplied a reference to a known good cable. I happened to have that very cable.

This host has been retired. The services were distributed amongst r730-01 and r730-03. This host was often referred to as r720 or r720-01 (after r720-02 appeared on the scene) This replaces a previous post. I’ve been given a Dell PowerEdge 720. It contains: 6 x 400GB SAS SSDs – data01 zpool 2 x 100GB SAS
Well, this isn’t very nice.

In this post, I’m not exporting an iocage jail to another host. I am moving the entire iocage instance to another host. This is accomplished by doing a zfs export on the zpool, moving the drives to a new system, and doing a zfs import. The drive migration is covered in a previous post. In

Today is the day. Today I move a zpool from an R710 into an R720. The goal: all services on that zpool start running on the new host. Fortunately, that zpool is dedicated to jails, more or less. I have done some planning about this, including moving a poudriere on the R710 into a jail.

Today the drive caddies arrived for the R720. I refer to the services provided by the R710, not the server itself. I will list those services later and outline how I want to move them. I could do all this over this coming weekend but I have already allocated that time to some errands I

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
