I have a problem with the creation of a volume group. I have the error
# vgcreate /dev/vglega /dev/dsk/c6t2d0
Warning: Max_PE_per_PV for the volume group (65535) too small for this PV
(369258).
Using only 65535 PEs from this physical volume.
Increased the number of physical extents per physical volume to 65535.
vgcreate: Volume group "/dev/vgeur" could not be created:
File too large
What's the problem?
Thanks.

Re: vgcreate problem
"vgcreate -s 32 /dev/vgeur"
The maximum number of PE is 65535 and the default size is 4MB so you ned to make them bigger

Re: vgcreate problem
The default size of 4 MB per PE is too small for this disk that you are trying to create the VG on .
So increase the size of the PE in powers of 2 to fit the size of the physixal disk .
do man vgcreate for more options ( seee the -s and -e options )

Re: vgcreate problem
problem is about PE_SIZE, see doc KBRC00009036.
You should execute vgcreate with -s option, e.g.
# vgcreate -s 16 /dev7vglega /dev/dsk/c6t2d0
I hope this helps you.
Best regards,
Ettore

Re: vgcreate problem
-increase the PE size
-decrease the max number of PV (def 16)
-decrease the max number of LV (def 255)
-use combo of PV/LV/PE size
ex:/
vgcreate -s 8 -p 5 -l 20 /dev/vglega /dev/dsk/c6t2d0
where:
-s = pe size
-p = max# PV
-l = max# LV
For a large lun/disk usually a combo of reducing the max# of PV/LV and the PE size should do it.
Hope this helps,
