Hi,

To fix this you need to increase your PE size from the default of 4Mb to something bigger like 8,16 or 32 ....

vgcerate -s (8,16,32) vg01 /dev/disk/disk5

Hello,

something might be accessing the disk you plan to include in your volume group. Check with:

# fuser /dev/disk/disk5.

Also check whether the disk is not used for some other purpose apart from LVM config.

# fuser -ku /dev/disk/disk5.

then try once more
#mkdir /dev/vg01
#mknod /dev/vg01/group c 64 0x010000
#vgcreate vg01 /dev/disk/disk5
