I read somewhere else about NFS issues on 7-RC* where snapshots

too - changing the exports file or reloading mountd gives the

Can this be related? I'm starting to worry here - what will be the
long-term consequences if snapshots are stuck around in this
"invisible" state?
Ok there is definitely something VERY fishy going on here.
I have just removed a lot of data from one of the partitions where I
HAD snapshots (they are all gone now, since days). So freespace
initially goes up a lot, as expected, then drops to around what it was
before the deletion took place. There IS a snapshot being maintained
somewhere, even though I have deleted it (using rm -f). What can I do,
short of rebooting or remounting the filesystem??
This behavior is also seen on 6.2-RELEASE by the way; entirely
different hardware (32bit vs 64bit, scsi vs ide, etc.)

I have been experiencing these too. But it looks more like a bug in
mountd, since it shows up only is snapshots are created with mount.
If snapshots are created with mksnap_ffs this does not seem to show
up.
I still have to make more in depth experiments, but before
experimenting by myself I'd like to have some more informed
directions on what to experiment.
