New configuration requires "max_pes" are increased from 1016 to 6652
The current and new Volume Group parameters differ.
An update to the Volume Group IS required
New Volume Group settings:
Max LV 255
Max PV 16
Max PE per PV 6652
PE Size (Mbytes) 32
VGRA Size (Kbytes) 896
Review complete. Volume group not modified
# vgmodify -v -t vg32
Current Volume Group settings:
Max LV 255
Max PV 16
Max PE per PV 1016
PE Size (Mbytes) 32
VGRA Size (Kbytes) 176
VGRA space (Kbytes) on Physical Volumes with extents in use:
PV current -n
/dev/rdisk/disk6 896 32768
/dev/rdisk/disk5 896 32768
Summary 896 32768
Volume Group optimized settings (no PEs renumbered):

Current Volume Group settings:
Max LV 255

Summary 896 32768
Physical Extent zero is not free on all PVs. You will not achieve these
values until the first extent is made free (see pvmove(1M)) on all the
following disks:
/dev/rdisk/disk6
/dev/rdisk/disk5
Volume Group optimized settings (PEs renumbered lower):
max_pv(-p) max_pe(-e) Disk size (Mb)
61 65535 2097152
62 65532 2097056
...
252 16048 513568
255 15868 507808
2.
Based on the output of
vgmodify -n -t
, choose 255 for
max_pv
and 15868 for
max_pe
.
3.
Since the new values require physical extent 0 to be free, use
pvmove
to move it to another
location:
# pvmove /dev/disk/disk5:0 /dev/disk/disk5
Transferring logical extents of logical volume "/dev/vg32/lvol2"...
Physical volume "/dev/disk/disk5" has been successfully moved.
