Maximum max_pe values for boot disks
The following table lists the maximum allowed max_pe (-e) values depending on
max_pv (-p) and pe_size (-s) along with their resulting PV sizes in GB. Since the lv_max
parameter has a lower impact on the results, the table is caculated for lv_max=255,
which is default and also a the worst-case. The fields for the default settings –s 4 –p 16
are shaded.
PE size (vgcreate –s pe_size) in MB
