Follow-up Comment #2, bug #64167 (project grub): I suspect you've hit this bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=987008 https://savannah.gnu.org/bugs/?61620
I've hit this issue myself and, having done a similar round of debugging, I'm also pretty sure grub is broken in the case where the LVM metadata isn't contiguous on-disk, which means that any LVM operation that touches the metadata could trigger this bug. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?64167> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
