Nicholas,
snap sched vol0 0 0 0 only turns off scheduling but the reserve is still there. To turn off the reserve you need to execute the command "snap reserve vol0 0" This sets the reserve percentage to 0%. By default the Netapp filers reserves 20% of your available disk space for snapshot. Please remember to delete your snapshots. Execute a "snap list vol0" to get the names of your snapshots and then you may delete them one at a time with the command "snap delete vol0 hourly.0" and et cetera.
Now the vol options volX nosnap on, according to the man pages, disables automatic snapshots but does not say that it sets the reserve to 0%. It may set the reserve to 0% if you included this options when you set up the volume. To check if your reserve is at 0%, execute a "df" command. It will tell you what you have reserved and what is in use.

Many people replied to my question about turning off snapshots. I guess it comes down to it, which method not only turns off the snapshot, but also turns off the systems reserving of disk space. (I know if I manually set it I will be ok) but does the command
snap sched vol0 0 0 0 do it or does vol options <volume name> nosnap on
I just don't want to have turned off snapshots, but still have the filer reserving space for them (I know this sounds kooky but I don't know if the microkernel will automatically save the space reguardless.)

Hi,
From the filer type
snap sched vol0 0 0 0
Repeat for each volume.
This is permanent until the next snap sched is issued. It can also be place in the /etc/rc file on vol0.

I'm setting no snapshots to be running and my disk usage to 0% (The machine is used as a cache server only, and the data is not critical in any way shape or form.
Is there an alternative method to shutting off snapshots? (i.e a snapshot off command, or something like that)
