Hi,

I was having trouble earlier with lilo, and while configuring it, I
wrote it to the mbr on a disk I had lvm on.  The only place I found that
mentioned this problem was in an email to this list in march 2001, over
two years ago.  It basically said that the lvm disk would be hosed.  Is
there anyway to get the data off the disk? or repair it?

if you have a recent metadata backup you can try using vgcfgrestore to put the metadata back on the disk.

other options depend on what was the disk layout:
was it the only disk you had in the volume group?
are there lv sharing more than one pv?
do you recall the LV layout?

Also, in the future, could I use the mbr if the pv was a partition
rather than the whole disk?

that would be a good idea. as much as i hate partition tables i found that just too much code in linux applications depend on having a partition table, so wasting 512bytes for a partition table entry is easier than fixing everything that breaks.
