For as long as the usage is below the hard limit (space or inodes) and
below the grace period you'll be able to write.
I don't think you can set the grace period to an specific value as a
quota parameter, such as none. That is set at the filesystem creation
time. BTW, grace period limit has been a mystery to me for many years.
My impression is that GPFS keeps changing it internally depending on
the position of the moon. I think ours is 2 hours, but at times I can
see users writing for longer.
