ERROR-060, DS-Extent space allocation failed for file 8.

Has anybody experieced this? I tried to load FNAT for the latest Natural release but it failed with the messages that are all pasted below. Looks like there is a problem with MAXRECL? Can anybody suggest how I fix this? Many thanks in advance,
Dave
