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. I last used Tarsnap back in July 2010 (I know that because I found the old Tarsnap registration […]

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 session and pressed control-C this morning: [root@knew:/usr/share/dtrace/toolkit] # ./hotkernel >> /var/tmp/hotkernel ^C ssh login loop It was suggested

I recently added 10 new HDD to a system which already had 10 HDD (now a total of 20). The HDD are split into two zpools: $ zpool list NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT system 27T 22.1T 4.93T – 19% 81% 1.00x ONLINE – tank_data 45.2T 26.3T 19.0T – 37% 58% 1.00x ONLINE – zoomzoom 436G 9.67G 426G – 6% 2% 1.00x ONLINE – The zoomzoom zpool is

This post has been replaced by a newer one.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. The filesystems, well, some of them: And dmesg:
The time has come for me to move from shelving to racks. My first thought was to list the various racks over the years. Look below for old photos and links to the posts I lifted them from. Why a rack? In the past, I have always built my own servers, computers, from parts. I always chose tower cases for space and quiet. A large fan and heatsink can be easily mounted in

For future reference, this is the knew server. It runs a few jails, including Bacula regression testing services. File systems Paritions zpools /var/run/dmesg.boot
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 know, I know. Why not use Bacula to restore that file. That would be too easy. I want

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 did not run last night, because there was no sa0, instead, there was an sa1, which was not

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 scbus0 target 10 lun 0 (da1,pass1) <ATA TOSHIBA DT01ACA3 ABB0> at scbus0 target 11 lun 0 (da2,pass2) <ATA

Yes, it’s time to build a new server because my current backup server is running out of space. This server will be used for more than just backups. What else, I’m not sure, but the servers it will replace also does these tasks (sorted by my estimate order
