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

This post has been replaced by a new one. For reference, the previous post on this server is still available. This server was upgraded on Feb 2 2019. Only the storage persisted. Everything else was upgraded. The hardware M/B – Supermicro X9DRE-TF+ RAM – 128GB composed of 8x 16GB DDR3 1600Mhz 21300 ECC/REG CPU – 2x E5-2620v2 – Intel Six Core 2.10Ghz Xeon 15MB cache 7.2 GT/s QPI (80W) chassis – SC846E16-R1200B SAS9300-8i
Tomorrow I’ll be doing some server and rack work. I’ll be moving one system into a new chassis, combining two desktops into the old chassis, and putting both chassis back into the rack. There are a bunch of steps here and I want to write them down so they all get done. These steps were completed last night: Remove tape01 and tape02 from the rack. Remove the shelf from the rack which held

Current FreeBSD versions will allow you to create a zroot zpool from which you can boot. However, when I created the main zpool for slocum (on Fri May 3 2:16 2013), that option did not exist. You might ask: how do I know that date? [dan@slocum:~] $ zfs get creation system NAME PROPERTY VALUE SOURCE system creation Fri May 3 2:16 2013 – At present, the system boots from a raidz2 zpool.

This post has been replaced by a newer one. For reference, the previous post on this server is still available. The most recent change was extracting the beadm boot environment to a new zpool, zroot. For future reference, this is the slocum server, which I use for various jails and services. It is mounted in the 4U chassis mentioned in this post The filesystems, well, some of them: And dmesg:
I have added comments to the output of this command. This is a brief description of what runs in each jail.
