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:
Review complete. Volume group not modified
# vgmodify -v -t vg32
Current Volume Group settings:
VGRA space (Kbytes) on Physical Volumes with extents in use:
PV
/dev/rdisk/disk6
/dev/rdisk/disk5
Summary
Volume Group optimized settings (no PEs renumbered):
max_pv(-p) max_pe(-e) Disk size (Mb)
2
3
...
213
255
# vgmodify -v -n -t vg32
Volume Group configuration for /dev/vg32 has been saved in
/etc/lvmconf/vg32.conf
Current Volume Group settings:
VGRA space (Kbytes) on Physical Volumes with extents in use:
PV
/dev/rdisk/disk6
/dev/rdisk/disk5
Summary
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
62
...
252
255
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.
