Why do you need fsstress to do this? Why can't you just run fsstress
in the background and run a loop creating periodic snapshots in the
control script?

Also, did you intend that every process creates a snapshot? i.e. it
looks lik eif you run a 1000 processes, they'll all run a snapshot
operation at X operations? i.e. this will generate nproc * X
snapshots in a single run. This doesn't seem very wise to me....

Cheers,

Dave.
