It would really be great if there was a snapshot deletion daemon that could delete the oldest standard (hourly, nightly, and weekly snapshots only) snapshot(s) when the snapshot usage goes above a certain number. So, "snap" could do a "snap highwatermark" command or something like that in a similar manner to the "snap reserve" command. - Dan

Hi Mike, When you delete files, the space formerly accounted for in the active file system now gets accounted for in the .snapshot area. Snapshot space consumed grows as you delete or modify files, and the more you change the larger the snapshot area becomes; think of snapshots as measuring the "delta" in a file system. Eventually the Netapp will free up space as the snapshots expire. If you need the space back right now you can delete snapshots manually via console commands. Do a "snap list" at the console to obtain a list of snapshots, and you'll get an idea of which snapshots are taking up the most space. Generally you want to start deleting the oldest snapshots first. You can delete one or more snapshots by using the "snap delete <snapshot name>" command, which will return space to the active filesystem as long as your overall snapshot utilization exceeds 100% of the snapshot reserve. This sounds a little complicated, but do a "df" on the filer after each snapshot deletion and check out the effect on active and snapshot utilization percentages.

Ummm, will it allow you to do partial copies (one directory hierarchy like ndmpcopy does) and copies from differently-sized filers? Dan

More about CIFS
by Alexei Rodriguez 20 Feb '98

20 Feb '98

There is an article (very timely) in the latest SysAdmin magazine by Bridget Allison (NetApp employee) titled: "integrating CIFS and NFS file sharing". >From it, here is the location for CIFS info: http://www.microsoft.com/intdev/cifs for those interested. Alexei

Gigabit ethernet
by Alexei Rodriguez 20 Feb '98

20 Feb '98

How many of you are testing or using gigabit on the filer? I have some friends that have been doing it, but only 66% success. The 1 person using the Alteon (or whatever the NetApp reccomended one is) got good results; but the density is lacking. Another person is using a Foundry switch between a filer (630) and a DEC alphastation. He is getting decent results. But the Foundry equipment is also less than dense (and will be expensive when they put the chassis systems out). Finally, another friend is using a Prominet Cajun switch (good density, excellent price) but cannot get the filer to "ring up" on the switch. Looks like it might be a Prominet issue. Has anyone tried other equipment? Cisco (beta tesing)? YAGO? Success stories? Horror stories? I need to go from FDDI to something faster (and less expensive). ATM is not it.. :) My plan is to put the filers on gigabit, as well as our backups machine and the heavy use clients (servers). The rest of the servers can use switched 100mbit. Thanks. Alexei

The Alteon NIC's (the ones NetApp sells and supports) work great with the Alteon switch (surprise!). I was supposed to have a meeting with a sales person this week but something came up and he had to cancel. They hinted at some sort of chassis solution in the future (as is everyone else). > Another person is using a Foundry switch between a filer (630) and > a DEC alphastation.

I wonder who that could be :) The chassis will indeed be expensive, but relative to the other chassis solutions will be very competetive as well as denser and featureful. I am anxiously awaiting it now. > Finally, another friend is using a Prominet Cajun switch > (good density, excellent price) but cannot get the filer to > "ring up" on the switch. Looks like it might be a Prominet > issue. It's probably a link negotiation problem. I haven't been able to get the Alteon NIC to negotiate with any switch. I dunno if Gigabit ethernet Link Negotiation is going to be as horrible as 10/100 Link Negotiation. Since my test NetApp isn't available to me right now, this is from memory: filer> rc_toggle_basic filer*> LinkNegotiation e10 0 filer*> rc_toggle_basic filer> That will turn it off the Link Negotiation and the NIC should immediately start working. We needed to do that to get it to talk to the Foundry switch. The actual command may be different, but "help" should get you all the way you need. > Has anyone tried other equipment? Cisco (beta tesing)? I'm trying to get a beta Cisco 7500 series NIC/blade to do testing with but it sounds like their not very far along (not even alpha). I cringe at the thought of doing gigabit ethernet on the Catalyst's 1.2gigabit backplane. > YAGO? Now that Yago is cabletron I don't think we'll see many yago made gigabit products. Cabletron has a 2 port blade for the SS 9000 (MMAC+) but haven't tried it either. Our Network Engineers refuse to even talk to them :) > Success stories? Horror stories? I know I've mentioned this before, but getting the gigabit working was one of the most painless things I've ever done. I've used NIC's from Alteon (on the netapp), Packet Engines (on the DEC) and Essential (on the DEC) and minus some small driver bugs have had VERY little problems. They all interoperated very well. > I need to go from FDDI to something faster (and less expensive). > ATM is not it.. :) NetApp's didn't do voice or video last I checked so why ATM? :) > My plan is to put the filers on gigabit, as well as our backups > machine and the heavy use clients (servers). The rest of the servers > can use switched 100mbit. I've never used Prominet's switch, but have heard some good feedback about them. Not as good as some other's, but good performance nonetheless. Depending on how many machines you have, getting a Foundry FastIron with a single or dual gig uplink may work well. Never use Extreme. Their products may be decent, but their sales people/sale engineers really rubbed me the wrong the way. Overall rude and deceitful. Plus, who wants purple switches? :) JE

ndmp copy?
by Alexei Rodriguez 19 Feb '98

19 Feb '98

I have heard of folks dumping an entire filer to another via ndmp copy. Next week I will be having to do something like that and was wondering what sort of speed I might expect (if this thing exists). Also, does it do snapshots as well? Alexei
