I am using LVM version 2.00.25.
The man page states that there is a ~256GB limit if physical extent size is set to 4MB, because number of physical extents per LV is limited to ~64K.
Is this actually still true with this version?
My system is set to 4MB physical extent size, and total size is 614GB, with number of PE's in the LV 157363.
No problems experienced yet.
See below for details.
Hints?
Thanks,
Lewis
