Hello everyone, I am having a problem adding the FREE PPS’ for hdisk0 to the /dev/lv01 filesystem. I am also New to AIX so please bare with me.

OS= AIX 4.3.2.0

I have tried to do this via information found in another post on this forum but received the following error
chfs -a size=+1 /dev/lv01
0516-404 allocp: This system cannot fulfill the allocation request.
There are not enough free partitions or not enough physical volumes
to keep strictness and satisfy allocation requests. The command
should be retried with different allocation characteristics.

Can you please assist me with the process of adding the free diskspace to the /dev/lv01 filesystem ?
Is there any additional information that I may be overlooking ?

Information about the system is listed below…

Good Afternoon,

You are trying to use chfs to increase the size of the LV, you should be trying to increase the size of the Filesystem instead ==

chfs -a size=+1 /vol2b

will increase the FS by 4MB. using "size=+1" says to increase the FS by 1 512-byte block, but your physical-partition size is 4MB and increases will always be done to the next full PP
