Y2K Testing & compliance
by Thomson, Michael 25 Sep '98

25 Sep '98

Hi there! I've been asked some questions by our Y2K project team, specifically related to NetApp, and I'm unsure how to respond. >From the web page (http://www.netapp.com/y2k_table.html) it seems that the only thing that is 'preliminarily evaluated' is DOT 4.1. Can anyone give the authorative answer to: 1) Are there any plans to use a hardware clock that stores 4-digit years? 2) What Y2K tests were performed on DOT 4.1 3) Have later releases (4.1.3, 5.0, etc.) had the same tests run on them before release? 4) Can customers get access to NetApp test plans and results, directly or via a non-disclosure agreement? More generally, are people inclined to believe that, once certified by NetApp, the appliances can be treated as 'any other' NFS server by client machines, or would you advocate specific interoperational testing with NetApp kit?

Re: Support for Network Time Protocol?

All I need is more NetApp crashes because > of NTP bugs. I should add that this happened to us just a few days ago: - xntpd died on our adminhost (that ran the cron job to set the NetApp dates) - time drifted by 8 minutes on the adminhost and the filers over the course over a few days - someone started having problems, managed to figure out that it was because of the time drift, and we fixed it. (Other people probably had problems, but didn't report them.) To prevent it from happening again, we're remotely monitoring the system time of the adminhost (using "mon") to make sure it doesn't drift off again. Incidentally, there seems to be no way to remotely query the system time from a NetApp (except by creating a new file and running stat() on it, or by using unsupported/hidden commands). However, I'm still saying that I don't want NTP until other supported protocols (such as NDMP) start working reliably. Dan

Re: Renaming quota trees

Yes, it is. Just shut off quotas, "mv" the tree, change /etc/quotas, and restart quotas. You may have some stale file handle issues on clients afterwards if there was an old tree with similarly named files in active use. Dan

Moving a secondary volume to primary
by marc_merlin＠magic.metawire.com 30 Jul '98

30 Jul '98

Hi, I have a filer with two volumes, and I'd like to remove the first volume and keep the second one only. Is it as easy as doing: - copy of /etc from the first one to the second one - remove the firt volume - boot on floppy - download - reboot. ? Also, not that I have any reason to do that, but if I wanted to put the first volume back, how does the filer know which volume to boot on?

midnight disk failure
by Daniel Quinlan 28 Jul '98

28 Jul '98

Does something about the timing of this disk failure strike anyone as odd or is it just me? I'm curious to know whether some checks only done once an hour, once a day, or if something else is at play. This happened on an 18 day old F630/FiberChannel running 5.0.1D1.

remove snapshot, or what?
by Dan Bethe 26 Jul '98

26 Jul '98

Hi there guys. I'm not the regular NetApp tech around here, so I have a quick weekend maintenance question. Our filer had about -60MB (less than zero) free when I last checked it. We're deleting plenty of space now, but it's of course moving the deleted data to the snapshot storage. Is it proper to delete the snapshot storage manually? Or will the filer give it up in favor of the normal NFS export? We have, for example, some '.snapshot' directories that contain redundant data. Is 'rm -rf' proper there, or what? Thanks a lot.

snapshot issue solved
by Dan Bethe 26 Jul '98

26 Jul '98

Ok never mind. I see that the 'snap' command does that. I removed the oldest snapshot and we had 450Mb free after a few mins. Thanks anyway! :)

ndmpcopy?
by Jim Davis 24 Jul '98

24 Jul '98

I need to move about 56GB of data from one F520 to another. Does anyone have experience using ndmpcopy for that? It looks like it might fit the bill, but I'd be interested in hearing of any good-bad-indifferent experiences with it, and particularly what rate it can transfer data from one filer to another.
