F.10 vgcreate(1M)
Message Text
vgcreate: "/dev/vgname/group": not a character device.
Cause
The volume group device file does not exist, and this version of the vgcreate command does not
automatically create it.
Recommended Action
Create the directory for the volume group and create a group file, as described in “Creating the
Volume Group Device File” (page 47).
Message Text
vgcreate: Volume group "/dev/vgname" could not be created:
Error: The physical volume "pvname" contains BDRA.
It cannot be added into volume group "/dev/vgname" because
this version does not support bootable disks.
Cause
The physical volume pvname is a bootable disk, and vgname is a Version 2.0 or Version 2.1
volume group. Version 2.0 and 2.1 volume groups do not support bootable physical volumes.
Recommended Action
Use the pvcreate command without the -B option to reinitialize the disk, as described in
“Initializing a Disk for LVM Use” (page 46). For example:
# pvcreate -f pvname
Use the vgmodify command to convert the disk to a nonbootable disk, as described in “Changing
Physical Volume Boot Types” (page 87). Alternately, use the pvcreate command without the -B
option to reinitialize the disk, as described in “Initializing a Disk for LVM Use” (page 46). For
example:
# pvcreate -f pvname
Message Text
vgcreate: Volume group "/dev/vgname" 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.
Cause
The volume group reserved area (VGRA) at the front of each LVM disk cannot hold all the information
about the disks in this volume group. This error typically occurs if you use disks larger than 100
GB.
Recommended Action
Adjust the volume group creation parameters. Use the –s option of the vgcreate command to
select an extent size larger than 4 MB, or use the –p option to select a smaller number of physical
volumes. For more information on these options, see vgcreate(1M). For recommendations on extent
sizes, see Appendix C (page 169).
