Do I need to be concerned with "partition does not end on cylinder boundary" on Red Hat Enterprise Linux?

Solution Verified - Updated -

Issue

  • fdisk is reporting "partition X does not end on a cylinder boundary"
  • will io get split and cause performance issues if partitions don't end on cylinder boundaries?
  • Based on advice from our storage vendor, we've changed the starting sector of a partition to 128, providing a 64 KB boundary and aligns with our SAN cache size for better performance.  When we use fdisk to display this partition, we get "Partition X does not end on a cylinder boundary."  Do we need to be concerned about this message?
