Is there any magic in getting a Filer running 5.3.4R3 with NIS on
to do netgroup lookups via NIS? Or do you always have to manually
copy the netgroup file to filer:/etc?
I've tried putting just "nis" in the nsswitch.conf file
for netgroup, but this didn't work. The nis_group file
is updated just fine, but this seems o be the only NIS
file that the Filer updates in /etc.
Thanks.

Did you have to install the hclnfsd or pcnfsd on the netapp? We get no
HCLNFSD/PCNFSD running on host when we try to connect.

I've tried Microsoft's Services for UNIX (by Intergraph) in place of CIFS
and it seemed to work fine. SFU Version 1.0 is an add on for NT 4 and SFU
version 2.0 is included as a service with W2K server versions.
For Intergraph's version, see:
http://www.intergraph.com/nfs/

This is not actually a good test. If you notice, the user has deleted the
snapshot each time instead of using the same directory. The deletion of
the directory is causing the filer to reset the directory information in
the restore_symboltable.
"restore_symboltable" keeps track of inode numbers and directory
information. With the re-creation of the snapshot and a new directory in
the snapshot, the user is causing the filer to want to perform a logical
level0 even though he has specified an …
[View More]explicit level1.
I don't think his test is relevant to our level1 problems because since we
did not change the important parent directories, i.e., /o/w/1/2/owNNNN12/,
the level1 would have only changed items that indeed did change using the
same filesystem.
For Deron, I would suggest repeating the test with a slightly different
preparation of data. I think the NetApp is interpreting the entirely new
snapshot, even though the filenames are the same, as a fresh set of data
that should be restored over the destination data.
Or do I have it wrong?

Dave:
It seems to me that innuendo and insinuation, pointed at your
competitors, is not quite worthy of an officer of a company proudly
claiming the position of market leadership. As much as I am trying to
justify your remark in a context of levity, the continuation of this
thread (below) seems to have pushed to the point where it is
embarrassing and demeaning.
Yael Melman at EMC was not even aware of the existence of this
mailing list. (Now she is, of course; BTW, the name …
[View More]Yael, two
syllables, ya-'el, is originally a Hebrew name, always uni-gender.)
Perhaps the actual Yael Hellmann would eventually come out and dispel
the affiliation mystery...
However, that's very much a moot point, even if, contrary to
evidence, we assumed that Ms. Hellmann worked for EMC. The actual
indictment by innuendo in this thread was that EMC was inimical to
NAS, since, allegedly, EMC was exclusively a SAN company. This is
simply untrue: EMC is the fastest growing vendor in the NAS market.

We have been putting "savecore" after "nfs on" for quite a while now. It
works as expected allowing client connections while the the core is being
saved into the file system. Unfortuantely, CIFS doesn't come on until
after the completion of all commands in "/etc/rc", so the only way to …
[View More]get
it on first is to not have "savecore" in there at all and just run it
manually. This doesn't seem like a good idea..
>and got a generally discouraging response, along the lines of "if
>turning NFS on provokes another crash, you could be in trouble".
Actually if you crash a second time before "savecore" has run, you merely
can't dump the new core. In fact, it says something like "Dupming core...
Can't dump, core already present on disk." IMHO, a problem that crashes
your filer that quickly should be visible in the first core. If not, just
boot off floppy and do a savecore. 99% of our NetApp crashes involve a
sucessful core dump and reboot cycle.

That could have been the fact that it was an FAServer 450. =) Our 300, 500, 600, and 700 series filers don't seem to have a problem handling NFS and "savecore" simultaneously.
