When Selecting replacements batteries for my Eaton 5PX UPS (5PX2200RT & 5PXEBM48RT), I began to think about: when the power goes off, why can’t I keep using my laptop? Usually, I still have an Internet connection: the ISP isn’t going offline. Why not turn off the two servers in the basement, and anything else

Today, I’m ready to adding two recently obtained 12T spinning disks to r730-03. This host is the work-horse which houses all the main backups and database regression testing. It also hosts my newly-created but not yet-functional graylog jail. I will be following a previous post about adding drives because I don’t want to remember these things. They occur infrequently enough that documenting it is a good idea. In this post: FreeBSD 14 The
