https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268100 --- Comment #2 from ml@netfence.it --- (In reply to Warner Losh from comment #1) First off, there are no "characteristics of the ZFS snapshot": we are talking about "zpool checkpoint", not "zfs snap". I have no idea on why loader.efi can't boot from a checkpointed ZFS pool: I only saw the message above ("can not read checkpoint data"). I don't have the original problematic pool anymore: it was a production server and I needed to boot it ASAP, so I just issued "zpool checkpoint -d" (that is, as soon as I relized what the problem was). I guess, in order to recreate the situation, procedure would be: install 12.3 UEFI+ZFS, checkpoint, upgrade to 13.1 (maybe upgrading boot loader is enough). The only thing I could add is it was a zraid5 pool (3 disks); not sure it matters. Importance is "less than bulk" to me: it would have saved me three hours of spreading panic if I had known; now I'll simply check if a checkpoint exists before upgrading (or, if I forget, boot from an USB key and remove it later). My only goal was to let other people know, so maybe they won't be hit so hard by this. -- You are receiving this mail because: You are on the CC list for the bug.help
