Full Discussion: Bypass stale PE ?
Operating Systems HP-UX Bypass stale PE ? Post 302905391 by port43 on Wednesday 11th of June 2014 09:44:35 AM

The pvdisplay is on the first page of this thread and looks fine to me, except for the one stale part.

I looked into the fact that it has a "strict" allocation policy and from what I glean from the lvchange command documentation, that just means that the mirror copies of extents cannot share the same physical volume, which makes sense because you wouldn't want your data mirrored on the same disk because if it failed ...

Code:
         -s strict                Set the strict allocation policy.
                                    Mirror copies of a logical extent can be
                                    allocated to share or not share the same
                                    physical volume or physical volume
                                    group.  This option only makes sense
                                    when the physical volumes of the volume
                                    group that owns the specified logical
                                    volume reside on different physical
                                    disks.  strict can have one of the
                                    following values:

                                    y    Set a strict allocation policy.
                                         Mirrors of a logical extent cannot
                                         share the same physical volume.

                                    g    Set a PVG-strict allocation policy.
                                         Mirrors of a logical extent cannot
                                         share the same physical volume
                                         group.

                                    n    Do not set a strict or a PVG-strict
                                         allocation policy.  Mirrors of a
                                         logical extent can share the same
                                         physical volume.

                                    When a logical volume is mirrored, the
                                    following changes are not allowed:

                                    +    From nonstrict to strict
                                    +    From nonstrict to PVG-strict
                                    +    From strict to PVG-strict

I thought I was onto something when I saw the -C contiguous option so I could skip the bad extent but that's not available for the root volume group.

pvdisplay

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

NAME

       pvdisplay - display attributes of a physical volume

SYNOPSIS

       pvdisplay  [-c|--colon]	[-d|--debug]  [-h|-?|--help]  [--ignorelockingfailure]	[--maps]  [--nosuffix] [-s|--short] [--units hsbkmgtHKMGT]
       [-v[v]|--verbose [--verbose]] [--version] [PhysicalVolumePath [PhysicalVolumePath...]]

       pvdisplay  --columns  |	-C  [--aligned]  [-a|--all]  [-d|--debug]  [-h|-?|--help]  [--ignorelockingfailure]  [--noheadings]   [--nosuffix]
       [-o|--options  [+]Field[,Field]]  [-O|--sort  [+|-]Key1[,[+|-]Key2[,...]]]   [--separator  Separator]  [--unbuffered] [--units hHbBsSkKmMg-
       GtTpPeE] [-v[v]|--verbose [--verbose]] [--version] [PhysicalVolumePath [PhysicalVolumePath...]]

DESCRIPTION

       pvdisplay allows you to see the attributes of one or more physical volumes like size, physical extent size, space used for the volume group
       descriptor area and so on.

       pvs (8) is an alternative that provides the same information in the style of ps (1).

OPTIONS

       See lvm for common options and pvs for options given with --columns.

       -c, --colon
	      Generate colon separated output for easier parsing in scripts or programs.  N.B. pvs (8) provides considerably more control over the
	      output.

	      The values are:

	      * physical volume device name
	      * volume group name
	      * physical volume size in kilobytes
	      * internal physical volume number (obsolete)
	      * physical volume status
	      * physical volume (not) allocatable
	      * current number of logical volumes on this physical volume
	      * physical extent size in kilobytes
	      * total number of physical extents
	      * free number of physical extents
	      * allocated number of physical extents

       -s, --short
	      Only display the size of the given physical volumes.

       -m, --maps
	      Display the mapping of physical extents to logical volumes and logical extents.

       --columns | -C
	      Display output in columns, the equivalent of pvs (8).  See pvs (8) for a description of other options with this form of pvdisplay.
