This post has been replaced by a newer post.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
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 testing and I received this email late on Sunday: Despite the promise of more information in the logs,

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 saw: [dan@knew:~] $ zpool list NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT system 90.5T
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:~] $ That count is 7, so why is it complaining about 6? The files look ok: [dan@knew:~] $ ls

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. The freebsd-update From memory, because the system is not back online as I type this, the command I

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 from FreeBSD 10.3 to FreeBSD 11.1 by making use of beadm. WARNING! Not all steps of the freebsd-update
