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 […]

This post has been replaced by a newer post. This is the previous post for this system configuration. For future reference, this is the knew server … oh wait, I think it’s this server which is was mounted in the 3U chassis mentioned in this post (perviously erroneously referred to as a 4U). It runs a few jails, including Bacula regression testing services. It is now mounted in a SuperChassis 846E16-R1200B This recent

I recently installed 6 SSDs into an R710. In this post, I will describe what I did to the empty SSDs before I started using them. short test I ran a short test on each one of the drives.

This is about FreeBSD 11.1 on my knew server. I recently replaced the 3TB drives with 5TB drives. Along the way, it didn’t boot, the swap was adjusted, I got concerned about power, and there was a brief CAM status: SCSI Status Error scare. Then today, the planned reboot, I started asking questions on Reddit and on Twitter. The booting issue BIOS cannot boot from drives which present only 4096-byte sectors. This is

In this power, the server is running FreeBSD 10.3. I am completely and unreasonably biased: ZFS is the best filesystem out there. Do not take my word for it. Ask around. Today, I started a process I’ve been waiting to do for a while. I am replacing the 3TB drives in a 10-drive raidz2 array with 5TB drives. These new drives are faster, I think perhaps cooler, and, more to the point, bigger.

While in Ottawa for BSDCan 2015 and PGCon 2015, I obtained a 4TB external USB HDD. It now contains copies of the videos back to 2012 for BSDCan and PGCon. This is for backup. All these videos exist elsewhere (e.g. Youtube) and I have these just for backup. NOTE: the videos for BSDCan 2015 and PGCon 2015 will be online as soon as they are available. There is no ETA. Here’s what it
