Does anyone know how (if), you can prevent a deleted directory from getting "snapshotted"?
We are going to be moving a 30G directory off of one of our filers, and we'd like the space actually freed. but when the nightly snapshot happens, that 30G is just going to end up in the snapshot taking up the same amount of space. I'd rather not have to start deleting snapshots wholesale (i.e. snap delete nightly.6) because I don't want to lose the snapshot data from the other directories in the volume. Is it possible to just delete the snapshots of this specific directory withing the volume without deleting the snapshots for the whole volume?
Thanks,
-Leigh

If you've managed to delete the stuff before the snapshot occurs, the 30G won't be in that snapshot. But, it *will* be in older ones, presumably. It won't get freed until all those older snapshots go away.
The only way (I know of) to get that space back sooner is to delete the entire snapshot. If that's wrong, I'd *love* to hear about it.
