6027-3960 [N] Changing the size of the static pagepool is not supported when RDMA is in use. Consider
using the dynamic pagepool feature instead.
Explanation
The static pagepool registers a large region with the RDMA stack. While GPFS IBM
Storage Scale is running, this region cannot be unregistered, effectively leaking RDMA regions for
changes of the pagepool size while GPFS IBM Storage Scale is running. This is handled better by the
dynamic pagepool feature, that uses smaller RDMA regions where unused regions can be unregistered
when changing the pagepool size.
User response
Consider enabling the dynamic pagepool through the
dynamicPagepoolEnabled config option, if the pagepool size should change
while GPFS is running. To change the size of the static pagepool, restart GPFS to properly update
the RDMA registrations.
