I am running zfs set on 3 x 300gb HD's, I do see my disk activity going crazy
all the time, is there any reason for it? I have nothing running on this system,
just did setit up for testing purposes. I do replicate data from different
system once a day trough rsync but that is quick process and I am not sure why
am I getting this I/O activity on the system.

I did try to see what is going on on the disk, I did try to kill any processes
that might be doing anything (there was rsync server setup, so I did kill
that..) Anyway when I do:
# fuser -c /d
/d:
nothing has any locks on it.

Any idea what is going on and why there is so much reading going on?
Thanks for help or suggestions.
