Hello, currently we export a GPFS file system via kernel nfsd (RHEL6). Now we will migrate to ganesha 2.5. I wonder whether we can do this in a transparent way, i.e. without any risk that the clients get 'stale file handle' events. This likely would mean to use the same fsid but also that ganesha creates the same file handles based on fsid and inode. We use NFS version 3 only. We do export the filesystems to whole subnets and it may become difficult to find all clients in advance and to reboot shortly after the migration. Already the fsid part is puzzling, because ganesha uses two(!) uint64 values, where kernel nfsd on RHEL6 requires an integer. Probably the two uin64 map to a 32-hex-UUID (=16 byte, 128bit) Thank you, Heiner Billich https://www.psi.ch
