This post has been replaced by a newer post.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

NOTE: I am not convinced of the value of doing these tests on a regular basis. smartd and smartctl are two utility programs included with the smartmontools package. On FreeBSD, smartmontools is installed via the sysutils/smartmontools port. Those programs can “control and monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (SMART) built

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

If you’ve read even a little of what I’ve written, the following points will not come as a surprise: I like FreeBSD I’m a fan of backups I use Bacula I like ZFS I have tape libraries In this post, I will cover all of the above and more. Photos will be included. New gear

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
