RE: Sharing Filers among different user groups
by Clawson, Simon 08 Nov '00

08 Nov '00

We run an F760 here, and it is accessed by two different groups. The data held by one group cannot be accessed by another. This is achived by using CIFS Shares under NT, and by using the UNIX file permission on the directories themselves, and by setting the NFS export up to have the correct Anon UID. You may need to alter your infrestructure to achive what you want though. We have made the whole sharing scenario possible by implementing it in a single NFS environment. We have one NIS master that servers the whole office, along with local slaves in each department. The only area where the Netapps has a single access point is in the NT domain, where it has to bind to a domain controller on one of the three subnets we have. All you need to do in this situation is establish trust relationships between the other NT subnets and map the Netapps accross these. Bit confusing all that..but it is do-able...

Veritas NetBackup backup hangs
by Jeffrey Krueger 08 Nov '00

08 Nov '00

We have recently cut-over to using Veritas NetBackup with NDMP to perform a mixture of backups to filer-attached-tape and 3-way backups to other filers with tape. We are running DOT 5.3.4R3P2 on a mixture of 630's and 760's against NBU 3.2 with a recent patch set (one that includes the 3-way fix). In both instance, we have found that sometimes a filer completes a dump (ndmp session goes away, backup snapshot is deleted, /etc/dumpdates is updates), but the backup job hangs in Veritas-land. This job hangs indefiately until manually killed, at which point it does not record the file history making the backup un-restore-able. We're growing very frustrated with this issue. BudTool has been backing these filers up for 2 years with NDMP and relatively few problems. So far, NBU support has been disappointing to say the least. Has anyone seen this? Is there a workaround or fix? Also, does anyone know the mechanics of the "/etc/ndmpdlog.*" files? They are poorly documented in the DOT manuals. All of ours are zero length, but its unclear whether this is supposed to be the case (no news is good news). Does anyone know what they are supposed to look like? -- Jeff -- ---------------------------------------------------------------------------- Jeff Krueger E-Mail: jeff(a)qualcomm.com Senior Engineer Phone: 858-651-6709 NetApp Filers / UNIX Infrastructure Fax: 858-651-6627 QUALCOMM, Inc.

Hi Gang, I'm looking for a few customers who are interested in using FrontPage server extensions (now called "Office 2000 server extensions") and/or IIS pass-through authentication with filers. Please reply privately. Regards, Paul Benn Network Appliance

rsh return code
by Brian Tao 08 Nov '00

08 Nov '00

Probably a dumb question, but I just had a gigantic Sunday brunch buffet, so my brain is halfway into a food coma. ;-) Is it possible to have rsh return 0 or 1 depending on the success of a command executed on a filer? For instance, I want my backup scripts to kick off a "snap create" before they proceed, but I want to check the exit status of the rsh so I have a chance to abort and notify the operator if the snapshot is not created. -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't"

RE: Permissions problem with CVS
by Davis, John 07 Nov '00

07 Nov '00

I'm guessing you've hit "unicode" conversions..try accessing the files/dirs with NT..this should force a unicode conversion.. -----Original Message----- From: Clarke, John L. (CIS) [mailto:John_Clarke@bose.com] Sent: Monday, November 06, 2000 2:34 PM To: 'toasters(a)mathworks.com' Subject: Permissions problem with CVS Hello, We ran into a weird problem last week. We moved several CVS directories from a SunOS server to our NetApp F740. When a user went to check in a file that had been originally created by another user, the final mv of the file caused a "rename: Permission Denied" message. We went into the directory in question and did some experiments. I can copy the file to a new name, create a new file, and do a "mv newfile oldfile", and it works. However, if I try to do the same thing with the actual files being worked on, the mv newfile oldfile gives me the same "rename: Permission Denied" message. The qtree is configured for mixed CIFS/NFS permissions, but all the file moves have been from the Unix side via NFS. We are thinking of changing the qtree settings to NFS only. Looking for a cure, John

RE: rsh/ssh return code

There is no concept of a command exit code in a currently shipping release. Rsh returns based on the success of the rsh call itself. We are considering moving toward making the return result of the last executed command be available via a special "result" command or something like that, but most commands don't currently return anything.

RE: rsh/ssh return code

> Hrm, yeah... I poked around FreeBSD's and rshd source, and it > doesn't seem to have a mechanism to pass return values back to the > client. SSH definitely does have this feature though... what is the > behaviour like with Data ONTAP's sshd? The short answer: sshd returns whatever rshd returns. More details: For Data ONTAP, sshd sits in the middle between an ssh client and rshd. sshd decrypts data from the client and forwards it via localhost to rshd to fulfill the request. It is rshd that actually executes the command. Results (including return codes) returned by rshd are then encrypted by sshd before being sent back to the client. Murphy Lam -- mlam(a)netapp.com

RE: Backup Exec on 760 NT filer
by Benn, Paul 07 Nov '00

07 Nov '00

Have you seen our white paper on NT based backup. It's a little long in the tooth but still useful. http://www.netapp.com/tech_library/3052.html The latest versions of Veritas BackupExec (8.x) supposedly now require that all backup clients have a backup agent installed. You can't install an agent on the filer. -----Original Message----- From: Coder, James (STP) [mailto:james.coder@guidant.com] Sent: Monday, November 06, 2000 3:55 PM To: 'toasters(a)mathworks.com' Subject: Backup Exec on 760 NT filer We are looking at using Seagate Backup exec to back up data on our NT 760 filer. It's currently running 5.6.3 and looking to move to 6.0. Have approx. 1TB of data and currently using NetBackup. Any comments, concerns, good stories that I can share?

Sharing Filers among different user groups
by newbie netapp 07 Nov '00

07 Nov '00

With the advent of the F840, we are thinking of doing some massive server consolidation: using a F840 to replace many existing nfs/cifs servers among different user groups. What are the issues with sharing a filer among different user groups? I can see: 1) uid issues: Dept A is already using uid 101 for user smith, and Dept B has a different smith, or has a 101 for a different users ... etc. 2) security issues: we want to make absolutely sure Dept A cannot see or mount or share Dept B's data. 3) what if Dept A is using a different DNS than Dept B's? I don't think we can run 2 different resolvers, one per exported volumes ... 3) similarly, for NIS, and NT domains. Any insights, comments are appreciated.
