Can anyone provide experiences with storage devices that use thin

with the storage device incorrectly reporting the usage allocation after
the files are deleted. I see this reference in the GPFS FAQ, but I’m
looking for some real-world experiences.
Most flash devices use thin provisioning internally.
What is the usage case of using thin provisioning on a GPFS file system?
I just can't think of why it would ever be needed or for that matter a
good idea. I would personally file it under crazy ideas never to
implement in a production system.
Surely you throw everything into the GPFS file system and then
overcommit on your quotas. At least that is I would say the philosophy
of GPFS.
