Hi, There are two edge cases where the above update instructions will not work. 1) Due to the VLAN re-write in ifconfig(8), if a user is using a host that is fully utilising VLAN tagging, the machine will not be available on the network until the second reboot. The user will either need IPMI/LOM access to the console to execute the second 'freebsd-update install' command or have a way of it being executed and automatically rebooting prior to having access to the host on the network again. 2) If a user has a 12.2 zpool checkpoint in play and booting via BIOS legacy mode, the machine will hang at next reboot with 'zio_read error: 5' 'ZFS: i/o error - all block copies unavailable' 'ZFS: can not read checkpoint data.' The machine will have to be rebooted with a boot ISO and the checkpoint will need to be discarded and the system will boot correctly again (rewind has been unsuccessful). Please note: This does not appear to be an issue where hosts use UEFI for booting operating systems or if zpool checkpoints are destroyed prior to the update process. Cheers, Jason. _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
