https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222425 Louis <lrb@minmet.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |lrb@minmet.org --- Comment #13 from Louis <lrb@minmet.org> --- I had this exact same problem (11.2), and this is the only page that I was able to find which had the same complaints. Nothing I did fixed it. Eventually, after wiping the disk, I tried a clean install, having concluded that it might be a hardware problem. It booted. Curious. Then it hit me: gpart backup ada0 | gpart restore -F ada1 gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada1 actually *is* the problem. I ended up manually repartitioning the disk with gpart create then manually creating the partitions (and doing the gpart bootcode bit as above). All works. Guesses: either something is wrong with backup/restore, or having a larger disk causes the problem. Since examining the output of "backup" doesn't indicate anything disk-size related that changes, I'm guessing that "restore" doesn't do quite the same thing as "create". Possibly if one did a "create" prior to the backup/restore, it might work out differently. Anyway, this has been my experience, so if nothing else works and you landed on this page, try my "solution" and good luck to y'all. (If nothing else, it got me to create an account!) -- You are receiving this mail because: You are the assignee for the bug.help
