You have enough free extents. You can use lvextend to increase file system

What kind of errors you see?

Hi:

You don't offer what commands are failing. However, '/dev/vg03_backup/backup' has the maximum number of extents that are supported for a version 1.0 volume group already allocated: 65,535.

Hi (again):

> ussing sam web page

This matters not. As I said, you have already allocated the maximum number of extents allowed for a LVM 1.0 format volume group.

To see the limits, do:

# lvmadm -t

Thanks
can you suggest any options ??

Re: vg and lv extend errors

Tim D Fulford — Thu, 12 Aug 2010 16:45:36 GMT

You have very few options..

- backup data in vg03
- destroy vg & recreate with a larger PE (Physical Extent size)
- #vgcreate -s 8 vg03_backup /dev/dsk/.......
- lvcreate the relevant LV's
- format the LVs (as required newfs etc)
- mount them
- restore data from backup....

Hi (again):

> can you suggest any options ??

Depending on the update release of 11iv3 you are running, you have the 'vgversion' command that enables in-place volume group migration from version 1.0 to version 2.x.
