I was curious how LVM1/LVM2 handles a crash in the middle of a metadata operation. I presume an operation such as vgextend will update the mapping in the VGDA section of the disk. What happens if you crash in the middle of updating the VGDA? Hopefully, you don't end up with a partial mapping. I can see a way of guaranteeing atomicity by maintaining two VGDA sections and including a timestamp at the end of each write. Does LVM do something like this?
