I recently migrated the zroot on r730-01 to a new pair of devices. I did not then configure swap for the swap partitions I set up. I’m going to do that now. I’m hoping this post from 8 years ago helps. In this post: FreeBSD 14.3 The first few sections include what’s in the system, and detects and fixes a few issues.

Ever wondered if software RAID is faster/slower than hardware RAID? I’m going to find out. It’s not complete, and I just thought of an extension, but What RAID-1 setup should I use for FreeBSD 6.0? is a work in progress. The extention I mention is to compare i386 against amd64. I may do that if I have time.
