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

Leave a Comment / Disks, FreeBSD, hardware, Open Source, ZFS / By /

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. Rather than pull the error drive and replace it, I opted to add in a new drive and […]

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) 2002-15, Bruce Allen, Christian Franke, www.smartmontools.org Drive found in smartmontools Database.

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

Leave a Comment / Bacula, FreeBSD, hardware, Open Source, tape library, ZFS / By /

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 saw things which needed to be corrected. In this post, I will adjust permissions on devices get bacula-dir

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

Leave a Comment / Bacula, FreeBSD, Open Source / By /

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 next task is configuring the tape library to work with Bacula. The first part of that is mtx-changer

This post has been superseded by a newer post. The new SFF-8088 to SFF-8088 SAS cables have arrived and have been connected to the LSI 9200-8E SAS card and to the Dell TL4000 tape library. The updated the dmesg output etc and appear on this page, for future reference. The significant portion is: I will have to investigate those no free space available messages later, but given all the devices are present, I

This post is deprecated by this one. I have a new SAS card for the tape server. This time, we are using an LSI 9200-8E SAS card. I’ve updated the dmesg output etc and put on this page, for future reference. The significant portion is: World, please meet tape01, the newest addition to my home lab, and reincarnated from an old server. The tape library itself is not connected because the cables For

Bacula btape test of Dell TL4000 LTO-4 tape drives

Leave a Comment / Bacula / By /

I hooked up the Dell TL4000 tape library tonight. I have bacula-sd.conf configured, but I do not have the autochanger configured or tested. I just wanted to run a btape test. A btape test is an essential part of setting up your tape drive with Bacula as it is the initial testing of tape drive compatibility I will do the other tape drive another day.

This post is deprecated by this one. After a failed first attempt to get the SAS card working with a tape library, John Baldwin suggested I try mfip (there is no man page for it), but I discovered it was a kernel module. I issued the kdload mfip command, checked /var/log/messages, and found the tape library and drives had been added: Jan 1 00:30:42 tape01 kernel: mfip0: on mfi0 Jan 1 00:30:42 tape01
