OK, situation before I try to change anything: root@hd45:~ # boot0cfg -v mirror/m0 [...] default_selection=3DF1 (Slice 1) root@hd45:~ # boot0cfg -v ada0 [...] default_selection=3DF1 (Slice 1) root@hd45:~ # boot0cfg -v ada1 [...] default_selection=3DF1 (Slice 1) Now try to change it to F2 through the mirror device: root@hd45:~ # boot0cfg -s 2 mirror/m0 # No error message or other indication that something went wrong! root@hd45:~ # boot0cfg -v mirror/m0 [...] default_selection=3DF1 (Slice 1) root@hd45:~ # boot0cfg -v ada0 [...] default_selection=3DF1 (Slice 1) root@hd45:~ # boot0cfg -v ada1 [...] default_selection=3DF1 (Slice 1) > Might it work properly if you upgraded the boot sectors to version 2,=20= > which is what you should get if you reinstall from current boot0cfg,=20= > presumably without touching the MBR data, but you'll have backups .. Well ... root@hd45:~ # boot0cfg -B mirror/m0 root@hd45:~ # boot0cfg -s 2 mirror/m0 root@hd45:~ # boot0cfg -v mirror/m0 # flag start chs type end chs offset size 1 0x80 1: 0: 1 0xa5 1022:254:63 16065 16418430 2 0x00 1023: 0: 1 0xa5 1020:254:63 16434495 16418430 3 0x00 1021: 0: 1 0xa5 768:254:63 32852925 1920667140 version=3D2.0 drive=3D0x80 mask=3D0xf ticks=3D182 bell=3D# (0x23) options=3Dpacket,update,nosetdrv volume serial ID b100-808f default_selection=3DF2 (Slice 2) root@hd45:~ # boot0cfg -v ada0 [...] default_selection=3DF2 (Slice 2) root@hd45:~ # boot0cfg -v ada1 [...] default_selection=3DF2 (Slice 2) Revert the change: root@hd45:~ # boot0cfg -s 1 mirror/m0 root@hd45:~ # boot0cfg -v mirror/m0 [...] default_selection=3DF1 (Slice 1) That did it! These machines have been in production for some time starting with FreeBSD 8.x and have been upgraded via NanoBSD style dd followed by reboot all the time up to 10.3, now. Hence I never = touched the bootcode. Actual reboot of this production machine in two weeks when we run our regular updates. But I expect that to "just work".
