Re: Boot loader stuck after first stage upgrading 11.2 to 12.0-RC2
Yes, that must be true but it does not hurt to get checked. And of course, lsdev -v from 11.x loader would be good too. Anyhow, I am afraid we have reached to point where more specific debug info is needed (printed out), with lack of output about disks at all, it must be related to floppy device checks.

If it hasn't gotten to the point of saying how much BIOS available memory there is, it's only halfway through loader main() and has hung before getting to interact(). In fact, if that line hasn't printed, but some disk drives have been listed, it pretty much has to be hung in the "March through the device switch probing for things" loop. If all the disks are listed, then it got through that entry in the devsw, and is likely hanging in the dv_init calls for either the pxedisk or zfsdev devices. -- Ian > > > > > > > > > > > > > > > > > > > > > > > > > > > > > On 29 Nov 2018, at 17:01, Mark Martinec > > > > > b...@ijs.si> wrote: > > > > > > After successfully upgraded three hosts from 11.2-p4 to > > > > > > 12.0-RC2 (amd64, > > > > > > zfs, bios), I tried my luck with one of our production > > > > > > hosts, and ended up > > > > > > with a stuck loader after rebooting with a new kernel > > > > > > (after the first > > > > > > stage of upgrade). > > > > > > These were the steps, and all went smoothly and normally > > > > > > until a reboot: > > > > > > freebsd-update upgrade -r 12.0-RC2 > > > > > > freebsd-update install > > > > > > shutdown -r now > > > > > > While booting, the 'BTX loader' comes up, lists the BIOS > > > > > > drives, > > > > > > then the spinner below the list comes up and begins > > > > > > turning, > > > > > > stuttering, and after a couple of seconds it grinds to a > > > > > > standstill > > > > > > and nothing happens afterwards. > > > > > > At this point the ZFS and the bootstrap loader is supposed > > > > > > to > > > > > > come up, but it doesn't. > > > > > > This host has too zfs pools, the system pool consists of > > > > > > two SSDs > > > > > > in a zfs mirror (also holding a freebsd-boot partition > > > > > > each), the > > > > > > other pool is a raidz2 with six JBOD disks on an LSI > > > > > > controller. > > > > > > The gptzfsboot in both freebsd-boot partitions is fresh > > > > > > from 11.2, > > > > > > both zpool versions are up-to-date with 11.2.
