Impossible to create a new VG

[enrico.nic]

Hi

Trying to create a new volume group, with a single file system o 100 Gb, I am obtaining this message from SAM:

The command used to create volume groups, /sbin/vgcreate, has failed.
The stderr output from the command is shown below. The volume group has not been created.

vgcreate: Volume group "/dev/vg01" could not be created:
VGRA for the disk is too big for the specified parameters. Increase the extent size or decrease max_PVs/max_LVs and try again.

What can I do ? Which parameters should I change.

Thank you in advance

Enrico

as per the man page for vgcreate:

/usr/sbin/vgcreate [-f] [-A autobackup] [-x extensibility] [-e max_pe] [-l max_lv] [-p max_pv] [-s pe_size] [-g pvg_name] vg_name
pv_path ...

You need to eihter increase the extent size using the -e option, or decrease the max PV/LV parameters, using -p or -l

Hi,

(Max PE) * (Max PV) * 8 must be less than PE size.

It's probably best to increase the PC size.

Please read as "PE Size (Physical Extent)"

Ok, I've created the group through the command line and it works.

Thank you
