NOTE: I wrote this post nearly two years ago, in May 2015. It has been sitting ignored and unloved in my Drafts. I’ve just published it today. I’m big on backups and I use Bacula. I have about 18 TB on about 350 tapes and about 10 TB of backups on disk. I want more.

The knew server is ‘frozen’ again. This has been happening daily at about O301 UTC each night. See my Twitter feed for background. In this post I will include details as I progress through the data. The server in question is knew (yes, that’s the hostname). dtrace hotkernel I left this running in an ssh

This post has been replaced by a newer one. For reference, the previous post on this server is still available. . This server recently moved to a rack-mount chassis. On an interim basis, it contains an LSI SAS 9101-16i. For future reference, this is the slocum server, which I use for various jails and services.

Last night, I moved a SAS card and had to renumber some devices. I also moved two SSDs into the same box (see photos). Those SSDs were the boot drives from the system from which I pulled the SAS drive. That box, tape01, contains the Bacula configuration file I need for this new box. I

Last night, I added a SAS card into a box which is connected to a tape library (photos here). After starting up the box, Nagios reported that the tape device was no longer present. I first added such checks back in 2012 and updated them for more recent acquisitions. This means that the copy-to-tape jobs

Yesterday and today, none of my Bacula copy-to-tape jobs completed because my tape drive was missing. Today, I reseated all the cables, and power cycled the tape library. In my ssh session, I did this: $ sudo camcontrol devlist <ATA TOSHIBA DT01ACA3 ABB0> at scbus0 target 2 lun 0 (da0,pass0) <ATA TOSHIBA DT01ACA3 ABB0> at
