I’m using FreeBSD 10.2-RC2 here, with a bunch of HDD. Here are the current pools: The degraded music pool contains a drive I will be replacing later in this post. But first, I want to replace a mis-matched drive in the benchmarking pool. I noticed that when I saw this output: The serial number on […]

I’m using FreeBSD 10.2-RC2. One of my new hard 3TB drives was acting up. I removed it and sent it off to be replaced. In the meantime, I received some 5TB drives and I added one of them into the existing vdev of the zpool. First, I partitioned the drive much like the other drives

I felt I was backing up way too much on my jail server. I was backing up files which would be installed as part of the OS. Let’s look at the esimate: *estimate level=full job=”slocum jail snapshots” Using Catalog “MyCatalog” Connecting to Client slocum-fd at slocum.int.unixathome.org:9102 2000 OK estimate files=2,824,716 bytes=239,568,332,325 * I decided to

In this post, I will use boot environments to upgrade an existing FreeBSD 9.3 to FreeBSD 10.1, and I will do this from within a chroot. Why? Because I can. You might want to read about my previous attempt and one or two, actually three, things I did to get ready for this. In the

Much like the system/bootenv/default/usr does not contain /usr issue I recently wrote about, I found the same issue with system/bootenv/default/var For this post, I have booted my FreeBSD 9.3 system from mfsBSD thumb drive. I will import the pool, but not mount it. # zpool import -N system I mounted the filesystem in question, and

I started trying a Root-on-ZFS upgrade using beadm and quickly encountered an anomaly: no /usr/bin Then, it was there, then it wasn’t. I wasn’t sure of what steps I took to reproduce it. So I went through logs and eventually understood what happened. Let me show you. Here is what I did: # beadm create

This is tallboy, the server I have at RootBSD. I like to store away this type of documentation, in case I need it later. This server was originally on UFS with gmirror. The partitions: The ada0 drive details: And ada1 drive details: And finally, dmesg:
I just converted another server from UFS to ZFS. I used this script as my starting point. I dropped to a shell as soon as I booted from the live CD. Then I fetch my script: fetch –no-verify-peer http://bit.ly/1MvhRXH mv 1MvhRXH install.sh I didn’t run the script. I modified it to suite my new conditions.
