I would like to record all filesystem activity so that I can later replay it at will (for benchmarking purposes). What's the best way of doing that?
I considered strace, but rejected that because it doesn't tell me when an
mmaped file is being read or written (same for other
inotify et all only tell when a file is being accessed (so I'm missing all the details of individual read/writes).
blktrace is great, but works at the wrong level (I need pathnames, not block offsets).
