Full Discussion: LVM PE. Best practice
Operating Systems HP-UX LVM PE. Best practice Post 302929393 by Scrutinizer on Saturday 20th of December 2014 11:27:18 AM

Hi,

It does not affect performance, but the choice does affect the maximum size of the VG and the LV's (maximum number of PE's x maximum PE size). So a large PE size ensures you can scale large enough, but it also means that volume groups and logical volumes will need to be extended with the granularity (steps) of the PE Size (or n times this size in the case of LVM striping) . In my experience the default of 4 MB is usually too small and it is better to pick a large PE size for future expansions..

pvck

PVCK(8)                                                       System Manager's Manual                                                      PVCK(8)

NAME

       pvck - check physical volume metadata

SYNOPSIS

       pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...]

DESCRIPTION

       pvck checks physical volume LVM metadata for consistency.

OPTIONS

       See lvm for common options.

       --labelsector sector
              By  default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0.  This parameter allows you to specify a
              different starting sector for the scan and is useful for recovery situations.  For example, suppose the partition table is corrupted
              or  lost  on  /dev/sda, but you suspect there was an LVM partition at approximately 100 MB.  This area of the disk may be scanned by
              using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):

              pvck --labelsector 204800 /dev/sda

              Note that a script can be used with --labelsector to automate the process of finding LVM labels.
