And that is, my main raidz2 system has a system boot zfs mirror pair that has boot partition size (Mediasize) of 64K, and when I tried to zpool upgrade that pool a year or 2 ago I got some scary message something like "boot partition size is not large enough". I asked about this on the lists but never received an answer. So, laziness required me to ignore the problem and not zpool upgrade any of my 15 or so zpools in the interim. A few weeks ago I tried to make buildworld/installworld upgrade 12->13 but the boot failed in the mounting filesystems phase with it couldn't find a bootable target. So after restoring 12 I decided to wait a bit. In the interim I have upgraded every zpool but that one system pool. All the other freebsd-boot partitions have a size of 512K. So what is the current advice? Is a freebsd-boot partition size of 64K laughably obsolete, and I should get with the program and repartition those disks, or can I march blindly into the upgrade? I guess I just want to understand where these sizes are going in the future. Many thanks, Russell
