This post has been replaced by a newer post.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 […]
This server, knew has had an intermittent problem related to CAM status: SCSI Status Error messages. There is a FreeBSD Forums post about it. On Sunday, the problem returned, and this time it degraded the zpool. I collected the information in this gist and I will list the relevant portions below. I had enabled smartd

On Monday night at about 5:30 PM, I noticed the email: ** PROBLEM alert – knew/zpool is CRITICAL ** What sickened me was that the email was sent at 3:58 PM. That makes me think I should add a Pushover.net alert …. I could do that at my mail server. Logging into the server, I
This problem was difficult to figure out. The cause was simple, but not obvious. Messages such as this were appearing in emails From July: In August: I had no idea why. My initial suspicion was the /etc/newsyslog.conf configuration for that file: [dan@knew:~] $ grep auth /etc/newsyslog.conf /var/log/auth.log root:logcheck 640 7 * @T00 JC [dan@knew:~] $

For future reference, this is the knew server … oh wait, I think it’s this server which is mounted in the 4U chassis mentioned in this post. It runs a few jails, including Bacula regression testing services. This recent post outlines the modifications so it boots off a mirror of SSDs. File systems Paritions zpools
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. I already had smartctl. $ sudo smartctl -t short /dev/da0 smartctl 6.6 2017-11-05 r4594 [FreeBSD 11.1-RELEASE-p1

Yesterday, I upgraded a DigitalOcean droplet from FreeBSD 10.3 to FreeBSD 11.1 just before I headed to work. I’ve done such upgrades several times before. They all went well. This one did not. Several issues cascaded to prevent me from completely this task in a timely manner. Let me describe the events as they unfolded.

Yesterday I modified a server from booting off a raidz2 array, to booting off a newly created zpool. Why? Because HBAs are a pain to boot off. Instead, this server is now booting off a ZFS mirror of two SSDs, both of which are directly attached to the M/B. Today, I am upgrading this server

I’ve been having boot issues with a server containing 20 HDD, all behind HBAs. I have decided to start booting off SSDs. In that previous blog post, there was much speculation about where to mount the new drives, etc. In the meantime, I came up with a solution which did not involve magnets and used
