Snazim se ted upgradovat jeden prehistoricky stroj, na kterem puvodne
bylo PC-BSD. Po upgrade by tam melo byt ciste FreeBSD 11.3 amd64 s
oficialnima balikama.
Pro upgrade jsem vytvoril novy Boot Environment (coz je klon puvodniho
root filesystemu) a v nem provedl upgrade OS i balicku.
PC-BSD jako bootmanager pouziva grub2.
Po rebootu si v menu grubu vyberu ten novy BE, system zacne bootovat a
pak to zacne vyhazovat chyby u pokusu o loadovani modulu:
KLD ipfw.ko: depends on kernel - not available or version mismatch
linker_load_file: Unsupported file type
Podobnych chyb se tam vyskytuje vice a system bootovani nedokonci.
Vim, co takova chyba znamena za normalnich okolnosti - ze mam jinou
verzi kernelu, nez moduly. Zkratka out of sync. Jenze kdyz nabootuju
predchozi funkcni verzi, primountuju si tento Boot Environment a
zkontroluju, co je v jeho /boot/kernel, tak je tam kernel i moduly te
nove verze 11.3-p7 (overoval jsem i checksumy).
Znovu jsem zkusil nabootovat do noveho BE, ale jako single user, coz jde
(nenacitaji se dalsi moduly). Znovu se podivam do /boot/kernel a opet
vse v poradku - novy kernel, nove moduly.
(rikal jsem si, jestli se mi tam tim grubem nemichaji pres sebe
mountovani dvou verzi rootu z ruznych BE, ale nevypada to tak)
Kontroloval jsem i kenv vfs.root.mountfrom a i tam je cesta ke spravnemu
(novemu) BE.
Grub je pro me tak trochu magie, tak nevim, k cemu by tam jeste mohlo
dojit, ze se nejakym zpusobem pomichaji ruzne verze kernelu a modulu.
Nebo co dalsiho tam jeste muze byt za problem, co zpusoby vyse popsanou
chybu?
Asi nejlepsim resenim bude, zrusit grub a pouzit standardni FreeBSD boot
manager
gpart bootcode -p /boot/gptzfsboot -i 1 ada1
