Does this reveal anything;
dtrace -n 'syscall::*write:entry /fds[arg0].fi_fs == "zfs"/ {
@[execname,fds[arg0].fi_pathname]=count(); }'
Alas, not much.
# time dtrace -n 'syscall::*write:entry /fds[arg0].fi_fs == "zfs"/ {
@[execname,fds[arg0].fi_pathname]=count(); }'
dtrace: description 'syscall::*write:entry ' matched 2 probes

freeram-watchdog /var/log/freeram-watchdog.log.1307796483 57
real 1m0.635s
user 0m1.436s
sys 0m0.361s
So during a minute of running I had about 3 seconds of DTrace script init
and appends to the log file every second (as well as TXG Syncs every
second). Strangely, no other files showed up, though previous rwsnoop
runs showed regular IOs (once a minute or more often) to a few other files.
Thanks,
