Sorta related ... can someone comment on, or point to a guide about the
relationship between partitioning, LVM and filesystems? In particular,
it seems to me that if you are going to the bother of partitioning to
boundaries, whatever you put into that should also be aligned.
There's no bother whatsoever entailed with current release media. If you
are setting all of this up on commodity hardware, it's all taken care of
for you.
So as to satisfy your curiosity, one exception I have encountered is
with systems that use LSI MegaRAID hardware. In this case, the
information required for tools such as pvcreate and mkfs.xfs to function
optimally is not conveyed to userspace. In the unlikely event that you
need to take matters into your own hands, you may find this informative:
