hi

I am trying to understand how big the lvm metadata is

in the vgcfgbackup file, I can see
extent_size = 8192
dev_size = 204800
pe_start = 2048
pe_count 24

pe_count(24) * extent_size(8192) = 196608 bytes usable space of the total dev_size(204800)
metadata size? = dev_size(204800) - 196608 = 8192

but...
pe_start is 2048?
so what is pe_start here? cant be sectors(512)? bytes? well than ther be not aligned

so where starts the actual data?
and where ends the lvm metadata?

regards Tomas
