fixing badly aligned storage

In the olden days, one would have to manually calculate[1] to get a file system (FS), in a logical volume (LV) that was part of a volume group (VG) living on a software RAID, properly aligned. I would get this calculation wrong in about 10% of the cases.

These days, modern Linux distributions like Fedora 14 and RHEL 6 parse hints from the storage.
