Added new drive when existing one gave errors, then zpool replace

In this post, I am working with FreeBSD 10.2 on this server. Over the past few days, a 3 year old drive has been giving errors. The number of errors has been constant, but I have a spare drive here, so I decided to replace it. I have verified that it is out of warranty.

smartd: Device: /dev/ada0, 8 Currently unreadable (pending) sectors persists

That smartd: Device: /dev/ada0, 8 Currently unreadable (pending) sectors problem which arose on Sunday is still around. I’ve run a short test, a long test, and a ZFS scrub is now underway. I may just replace the drive. $ sudo smartctl -P show /dev/ada0 smartctl 6.4 2015-06-04 r4109 [FreeBSD 10.2-RELEASE-p9 amd64] (local build) Copyright (C)

Using a Dell TL4000 with Bacula’s bacula-sd on FreeBSD with ZFS

Last night, I managed to install new (but used) SAS cables for my Dell TL4000 on the tape01 server. I managed to get bacula-sd running, but I was unable to communicate with it from bacula-dir, via bconsole on my laptop. Eventually, I ran bacula-sd from the command line in the foreground and with debugging and

Dell TL4000 tape library: running btape and configuring Bacula’s mtx-changer

In this post, I am using FreeBSD 10.2 and Bacula 7.4.0. I am now the proud second-hand owner of a Dell TL4000. The first thing I did was add an air filter. Why? Because I can. I got one made, with custom dimensions, by DEMCiflex. You can see that filter here in this photo. My
