RE: 3rd Party NFS Clients

For those of you using NFS Maestro to log onto NetApps from NT workstations, what authenticates the user? I get "Authorization Error" when logging in, unless I'm user "nobody" with no password. Thanks, Jen Hamilton

ndmpcopy problem (long)
by Deron Johnson 28 Mar '00

28 Mar '00

I had a need to transfer transfer a large amount of data between two filers, one running OnTAP 5.3.4 and one running OnTAP 5.3.4R2. I ran a level 0 ndmpcopy the day before the cutover, and then a level 1 the night of the cutover, in order to minimize downtime. However, after doing a compare of file sizes after the transfer, I found that some files which had been modified since the level 0 did not have the proper size on the destination. Here is an example. Toaster1 is the source, and toaster2 is the destination. I have added some comments in UPPER CASE. -------- # cd /toaster1/test # ls -l total 80 -rw-r--r-- 1 root other 37817 Jan 31 15:54 testfile SIZE OF ORIGINAL FILE IS 37817 BYTES. # rsh toaster1 snap create vol0 testndmp creating snapshot.................................... # ndmpcopy toaster1:/vol/vol0/.snapshot/testndmp/test toaster2:/vol/vol0/test -level 0 Password: Connecting to toaster1.

Do you have NIS for netgroup lookup in your /etc/nsswitch.conf file?

If I use an NIS netgroup name for which the system is a member, I cannot mount the volume. Is there a way to see what NIS information the Filer thinks it has cached? Tim

Can anyone help with this problem I have. We have a F760 Ontap 5.3.2rd4. I have a Sun 5500 server that we NFS mount volumns on the Filer for Unix people. The complain I have heard is that copying large files from on directory to another on the filer takes to long. for example a 40-50meg file may take 3 or 4 minutes. I have never heard this complaint from the NT side. We have a person trying to install an oracle database and this problem was discovered. I have both Nics on the filer trunked and I have checked mosr everything netapps suggested. This filer does not have that much traffic on it and it seems to be doing alote of writes. The Nt people are using the 9gig drives and the UNIX voumns are 18gig drives. If you transfere these files out over the network it only takes a few seconds. Is there an answer to this problem, I have not been able to find one yet. pwalker2(a)csc.com

The filer does not copy the NIS maps into /etc. NIS group information is cached, but otherwise the filer acts as a NIS client only, and will query the NIS server it has bound to ("nis info" will tell you which this is).

NIS and netgroup file
by Timothy Demarest 28 Mar '00

28 Mar '00

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. -- Timothy Demarest ArrayComm, Inc. demarest(a)arraycomm.com 2480 N. 1st Street, Suite 200 http://www.arraycomm.com San Jose, CA 95131

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/ Here's a link to Microsoft's SFU: http://www.microsoft.com/NTServer/nts/exec/overview/sfu.asp -----Original Message----- From: Jen Hamilton [mailto:jhamilto@n2h2.com] Sent: Monday, March 27, 2000 1:08 PM To: toasters(a)mathworks.com Subject: 3rd party NFS client Has anyone used a third party NFS Client application on the NT side such as Hummingbird's NFS Maestro to connect to a NetApp instead of using CIFS?
