We are considering deployment of PVFS for our cluster. We are going to have multiple PVFS I/O nodes, each with about 50TB of storage.
This poses a problem in that e2fsprogs (RHEL 6) currently can not make a filesystem larger than 16TB. I know that there's a newer e2fsprogs available but it's not in RHEL 6 and we are trying to stay supportable by Redhat rather than manually applying updates. If we build multiple 16TB filesystems on each I/O node, is there a way to make a single PVFS server instance use all of the filesystems on the node? Or do we need to run multiple server instances on each I/O node, one for each 16TB partition? Any comments on this or best practices for handling > 16TB filesystems via PVFS would be appreciated. -Roger Moye ----------------------------------------------------------- Roger V.
