Summary: Spurious warning about missing LVM PVs from 'grub-probe -t partmap' Project: GNU GRUB Submitted by: maxb Submitted on: Sat 06 Apr 2013 20:39:49 GMT Category: Disk & Partition Severity: Major Priority: 5 - Normal Item Group: Software Error Status: None Privacy: Public Assigned to: None Originator Name: Originator Email: Open/Closed: Open Discussion Lock: Any Release: Release: other Reproducibility: Every Time Planned Release: None _______________________________________________________ Details: I've been trying to determine why the grub installation process on one of my machines logs seemingly scary warnings: grub-probe: warning: Couldn't find physical volume `pv1'. Some modules may be missing from core image.. (and the same for pv0) Upon investigating, the warning is being printed by the command: grub-probe -d /dev/mapper/vg0-syslv -t partmap The system setup is a relatively simple one, with two disks, sda and sdb, each of which containing a single whole disk partition which is an LVM PV. The only detail which is slightly interesting is that the partitions start at sector 2048 rather than the traditional sector 63 (I had to move them further into the disk when a GRUB image supporting LVM outgrew 62 sectors). Some staring at the output of running grub-probe with --verbose suggests that the problem is that it is not considering partitions as worth probing for PVs. System is running Ubuntu raring with packaged GRUB 2.00-13ubuntu2 _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?38677> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/ _______________________________________________ Bug-grub mailing list Bug-grub@gnu.org https://lists.gnu.org/mailman/listinfo/bug-grub
