Although likely not the access model you are seeking, GPFS is mentioned
for the swift-on-file project:
* https://github.com/stackforge/swiftonfile
Openstack Swift uses HTTP/REST protocol for file access (ala S3), not
the best choice for data-intensive applications.

Subject: [gpfsug-discuss] OpenStack Manila Driver
Dear All,
We are looking forward to using the manila driver for auto-provisioning
of file shares using GPFS. However, I have some concerns...
Manila presumably gives tenant users access to file system commands
like mmlinkfileset and mmunlinkfileset. Given that mmunlinkfileset
quiesces the file system, there is potentially an impact from one tenant
on another - i.e. someone unlinking and deleting a lot of filesets
during a tenancy cleanup might cause a cluster pause long enough to
trigger other failure events or even start evicting nodes. You can see
why this would be bad in a cloud environment.
Has this scenario been addressed at all?
Cheers,
Luke.
