Folks,
We have a problem with files disappearing from a filer. The box is a 520 running 5.2.1. THREE times now, we've mounted one of its volumes to a production box, done tar cvf - | ( cd mount_point; tar xvf -), diff -r with no errors -- and then a day or two later the files that were copied are gone. Directories are there still, and symbolic links, but NO FILES.
Snapshots were turned off after the second time it happened; snap reserve is set to 0% and snap sched is 0 0 0 for that volume. There are no remarks in messages -- nothing besides [statd] time, up x days. The directories show size but ls returns nothing.
This is the volume on the netapp, mounted on the sun box:

There were no problems with applications pulling files from these directories on the netapp on Friday, Dec 18. This volume is not mounted anywhere else. This is a production system -- nothing writes to the mount point.
What happened Saturday morning at 5 AM? Why did all these directories get touched?
