Extending a file storage pool is easier for the administrator than extending a logical volume storage pool. All that is required is sufficient free capacity in the associated logical volume storage pool. A file storage pool can easily be extended with the command “vios chsp“, whereby the storage capacity to be added must be specified:
$ vios chsp ms05-vio1 filepool +5g
$
In the example, the storage pool filepool has been extended by 5 GB:
$ vios lssp ms05-vio1
POOL TYPE SIZE FREE ALLOC BDS
rootvg LVPOOL 558.00 GB 53.00 GB 512.00 MB 0
filepool FBPOOL 14.94 GB 13.94 GB 512.00 MB 1
$
The capacity has grown from 9.96 GB to 14.94 GB.
