Install grub2 on LVM partition












0















I would like to install grub2 on an LVM partition, i.e., not the MBR. I have a BIOS partition (not GPT) /dev/sda2 which contains an LVM volume group with two logical volumes. One is formatted with ext4 and mounted as /boot.



Running grub-install /dev/sda2 yields



Installing for i386-pc platform.
WARNING: Failed to connect to lvmetad. Falling back to device scanning.
WARNING: Failed to connect to lvmetad. Falling back to device scanning.
WARNING: Failed to connect to lvmetad. Falling back to device scanning.
grub-install: error: unable to identify a filesystem in hostdisk//dev/sda; safety check can't be performed.



How can grub2 be installed in this setting?
