Excuse me if I ask something probably obvious, but was this done with the Java version of NDMPcopy '-level i' or '-level 0' (and than '-level 1', and so on...)? > Anyway, I'd say go ahead but make sure you see both "DUMP IS > DONE" _and_ > "RESTORE IS DONE" on all of your copies, or do them over > before proceeding > to the next incremental. Thanks for the tip. I guess this would require constant attendance during the whole operation. > A tool like rsync on a fast client or two can help a lot. In the light of all the potential problems, this definitely seems like a good idea, especially before the final volume switch. As a side note, does anyone know of native (i.e. not Java) UnixWare 7 or Win NT 4 binaries of NDMPcopy and rsync? Robert

upgarde from F740C to F820C
by max chan 07 Jun '01

07 Jun '01

dear all, Anyone can give me some idea how to upgarde from F740 Cluster running 5.3.1 to F820 cluster? I have currently a F740c. one have 2 diskshelf and 2 vol with it. The other one have one diskshelf and one vol. All using 36G harddisk. I need to plan for an upgarde from F740c to F820c. I don't know whether upgarde to 6.x first b4 move to F820c will help. Or should i choice backup and restore? of course, downtime is another concern. Max __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!

Sudden CIFS performance degradation
by Dianna Mullet 07 Jun '01

07 Jun '01

We're running OnTap 5.3.6 on an F760, serving both NFS and CIFS. It ran fine since we upgraded to 5.3.6 around 10 months ago, until early this week, when we began experiencing severely degraded CIFS performance. In some cases, CIFS times out and the client experiences data loss. What should I be looking for? We had a similar problem with our other filer a few months ago, but never determined the cause; we ended up solving the problem by upgrading to OnTap 6. This time, I would like to determine the cause _before_ we upgrade, but time is of the essence. Help/tips appreciated. Thanks, Dianna

RE: Unix applications accessing ntfs qtree
by Muhlestein, Mark 07 Jun '01

In that case it doesn't sound like the app is trying to set Unix security. Yes, the filer maps the UID to a SID, but as described in the FAQ, you can't set Unix security in an NTFS qtree no matter what NT user you map to. Assuming you've unsuccessfully tried to use the security troubleshooter to diagnose this, open a case with Netapp and get them a packet trace, along with the exact permissions of the files in question and the "wcc -dvv" output. Alternatively, if it is a standard application, give them a full description of how to reproduce this.

But if I change the folder permissions to full control I can then save a file from a 3rd party Unix/Solaris application. Also doesnt the filer map a user's UID and GID to a SID. ---------- Original Message ---------------------------------- From: "Muhlestein, Mark" <mark.muhlestein(a)netapp.com> Date: Wed, 6 Jun 2001 17:52:58 -0700 >See the security troubleshooter FAQ: > >http://now.netapp.com/NOW/knowledge/docs/olio/guides/53_troubleshooting/faq… > >"I tried to 'gunzip' (un-tar, check out, etc.) a file in an NTFS qtree and it failed!

Moving data from one volume to another
by Robert.Sabo＠ecomm.bc.ca 07 Jun '01

07 Jun '01

Hello all, We have a F720 filer where the data from one volume needs to be copied to another volume in the same filer. From the previous discussions on this mailing list, it appears that NDMPcopy 'infinite incremental' feature is the solution which provides the shortest possible downtime. What I would like to ask more experienced NetApp admins is whether there are known caveats in issuing something like: jndmpcopy filer:/vol/vol1 filer:/vol/vol2 -sa root:<passwd> -da root:<passwd> -level i Data ONTAP version is 6.01R1, and there is ~ 43 GB of data that needs to be moved. Any feedback on positive/negative experiences with this procedure is highly appreciated. Robert
