Load Generator Configuration Notes

All filesystems were mounted on all clients.

Each client has all file systems mounted from one node.

There are 8 filesystems: fs1, fs2, fs3, fs4, fs5, fs6, fs7, fs8. All of them are cluster mounted on all the 8 server nodes. NFS shares are clustered, i.e., each server node exports a share per filesystem, for a total of 8 shares. This means that each server node can service IO requests from/to any of the 8 filesystems: fs1, fs2, fs3, fs4, fs5, fs6, fs7, fs8. Each SpecSFS load generating client connects directly to a server node, accessing all the 8 shares on that node, therefore do IOs to all the 8 filesystems.
