You can do:
snap create before_delete delete files snap delete before_delete
But this will not bring you into any better situation than the beginning one...
Usually I view it like a cake - you cannot eat it and expect it to be still complete - if you want to be able to restore files you will have to keep the snapshot. If disk space is more important at this point, just delete old snapshots OR change snap reserve.

List,
Is there any way to cheat with snapshots so that data in them can be deleted?
I have stupidly let a volume on my filer grow to capacity and want to free up space my moving files to another volume, if I just move the files I will get no gain in free disk space because the files will exist in the snapshot right?
Could I cheat this by taking a snapshot of the volume before I delete the files then delete the snapshot after the file are deleted?

hello,
I'm trying to create an access list of specific servers that are allowed to NFS mount our filer, but it seems im not doing something right. I know you can use ip netblocks with the exportfs command, but I need more granular security than that.
this is what i tried in /etc/exports: /vol/vol0 -anon=0,access=all_clusters
all_clusters refers to a netgroup I created in /etc/netgroup with the following entries: mail (mail1.mydomain.com,,) (mail2.mydomain.com,,) dns (dns1.mydomain.com,,) (dns2.mydomain.com,,)
After setting up these two files I ran exportfs -a to load the /etc/exports, the result was that nothing could mount the filer, even the machines listed in netgroups. The mounting error was "permission denied"
Currently I "exportfs /vol/vol0" as the current config, obviously I need to tighten this.
Reading further about exportfs i see that there is a "rw" option, but it does not accept netgroups..
Im sure somebody else has done this before a million times, what am I missing?
thanks a lot, -jc
I forgot to paste the last line of my netgroup file in the previous email, it should be:
mail (mail1.mydomain.com,,) (mail2.mydomain.com,,) dns (dns1.mydomain.com,,) (dns2.mydomain.com,,) all_clusters mail dns

Take a look at /etc/nsswitch.conf on the filer and be sure you have the line
netgroup: files
If you've got this, then look for syntax errors in /etc/netgroup.
Another possible problem, is reverse DNS lookup. When you export to hostnames (rather than a network block) then when the mount request comes in from the NFS client, the filer takes the IP address of the client (included in the mount request packet) and looks up the hostname with it. Then it checks the export list to be sure the hostname is listed.
Use nslookup to see what your DNS server returns when presented with the NFS client's IP address. Is that the same hostname you are exporting to? If not, then the mount request will fail. Sometimes DNS is not even configured to do reverse lookups, so that will certainly prevent exports to hostnames from working.
If your DNS server is the problem and you can't fix it, then you can always use a local /etc/hosts file on the filer. Put in entries for all your NFS clients and put this line in /etc/nsswitch.conf:
hosts: files dns
But you really ought to fix your DNS server if it's broken.
