Extending logical extents

[hmorrison]

How do i extend the number of logical extents so that I can create a logical volume larger than 260Gbs in HPUX 11.11

Hi:

You must have created the underlying volume group with a sufficiently large physical extent size ('-s pe_size') to be able to obtain the space you desire when the value of that 'pe_size' (in MB) is multiplied by no a value that does not exceed 65,535. The value 65,535 represents the largest number of logical extents allowed for any logical volume.

See the manpages for 'vgcreate' and 'lvextend' for more information.

In the event that your 'pe_size' is too small, you will have to destroy
and recreate your underlying volume group from scratch, first.

hi;

you gave 4 mb as extend size when creating the vg. so you can create max 65535 X 4mb. logical volume. you cannot change this parameter. You must recreate volume group. take your backup, recreate volume group and logical volume then recover.
