From time to time, my Bacula – space and time website shows some old jobs that need to be copied to tape. Stuff from 100 days or more. There’s no reason to copy stuff that old to tape. It’s already been copied to tape. So why does it appear? Last night I swapped some tapes in the tape library. This morning they would have been used and recycled. I’ll bet that those tapes […]

In this post, we’re going to demonstrate why aligning your disk partitions can be a good idea. For starters, we’re going to go with the default alignment, do a test, then align, and redo the test. But first, in case you have no idea what I’m talking about, this randomly discovered post may be a useful primer. Create the scheme on the disk This command creates a GPT scheme on the drive. Create

During a recent install of FreeBSD 9.1 onto a gmirror, it was pointed out that my disk partitions were not aligned. Today, I’ll look at how that affects performance, both before and after alignment. Last night, I installed FreeBSD 9.1 onto a separate HDD, which I’ll use as a floater. I can attach this HDD to any system I need to work on without booting from the main HDD. In attached this HDD

Late last week I installed FreeBSD 9.1 onto a gmirror, which I created during the install process. I documented it via photographs and comments. Hopefully, the next time I do this, it will be useful to refer to this resource. NOTE that when I did this, the partitions were not aligned properly. See the comments in the above URL for details. I will be covering this in a future post.

I wrote this some time ago, but never published it. Here we go… Bacula is a fantastic backup solution. It’s open source. It uses a database to keep track of backups. I’ve been writing recently about using ssl-admin as a certificate authority tool. Today, I started using ssl-admin for generating certificates for my backup clients. In this post, I’m using Bacula 5.2.12 and using this reference page as a guide. I started playing

I think I may have to put together a new server. For home use. Here is what I’m thinking of getting: SUPERMICRO MBD-H8SGL-O ATX Server Motherboard : $224.99 AMD Opteron 6128 Magny-Cours 2.0GHz 8 x 512KB L2 Cache 12MB L3 Cache Socket G34 115W 8-Core Server : $259.99 Kingston 8GB 240-Pin DDR3 SDRAM ECC Registered DDR3 1600 Server Memory : 4 x $59.99 = $239.96 PC Power and Cooling Silencer MK III 600W

I’m sitting in the The Warden – FreeBSD and Linux Jail Management talk at EuroBSDCon 2012. He has mentioned two things, so far, that give me ideas. Evil ideas. Put each jail in a different ZFS data set – this may be useful for my jails running Bacula regression testing Schedule cron jobs to do snapshots on a regular basis – useful for snapshots, which I’m not really using at all And he’s
