First, all credit goes to Mark Felder’s blog post upon which this is based. You can buy an Apple Time Capsule (I did) to back up your Mac. Now that I have two MacBook’s, I have run out of space, so now I want to backup to ZFS. By backing up to my ZFS filesystem: […]

NOTE: this post has been replaced by a newer version. The older post is still available This is x8dtu (named after the Supermicro motherboard). This will be the new FreshPorts server. In short: FreeBSD 11 booting off a mirrored pair of zfsroot SSDs 4.5TB of mirrored ZFS 196612 MB of RAM (yeah, that’s 196GB of
I have recently added two 480 GB SSDs to a 10 x HDD raidz2 system. The SSDs will be mainly used for spooling to tape during backups, but I’m going to use a small part of it for a SLOG. Not all systems benefits from a SLOG (Separate intent LOG), but synchronous writes, such as

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

I do have a FreeBSD-11 box, cuppy: $ uname -a FreeBSD cuppy.int.unixathome.org 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r279394: Sat Feb 28 21:01:21 UTC 2015 dan@cuppy.unixathome.org:/usr/obj/usr/src/sys/GENERIC amd64 $ That box is used mostly for testing and/or erasing DLT tapes. The current status of that box is not healthy. It’s running fine, but it is not optimal: Let’s

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.
Added new drive when existing one gave errors, then zpool replace Read More »
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)

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

Yes, this was not fun. I took some notes, but not everything. Please read the notes if you plan on doing these foolish things. I was cleaning up /usr/src on a host which does not hold src. I looked and found: It was there that I knew I’d done the wrong thing. Trying snapshots Let’s
