I know how LVM allocates extents, and it doesn't allocate *less* than what you ask for, only more. This is a case where it is allocating less, and thus the reason for my question.
So, if I have a 4M PE size and ask for 35M, I will get 36M because that is in an increment of 4M. I won't get 32M because it is less than what I requested.

This can cause discrepancies in your allocations unless they are exact multiples of the size of the extents. -- Benjamin Franz _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
