NFSv4/krb5: name<->ID mapping just doesn't work.
by Nathan Patwardhan 18 Dec '07

18 Dec '07

Hello, I'm using an SLES 10.1 client (x86_64) client to mount a NetApp that's running OnTap 7.2.3. My LInux client is bound to Active Directory. My NetApp is bound to my Windows Domain (cifs setup->Option 1, Windows 2000 domain) and 'cifs domaininfo' looks fine to me. NFS was setup to use Kerberos on the NetApp. I'm able to mount my NetApp volume as type nfs4/sec=krb5 and I am able to browse my nfs4 mount. However, by default everybody's permissions are set to nobody:nobody which means that my mapping for users is completely not working. At first, i'd thought that this was strictly an issue with my nfs4 client (i.e. idmapd), but as I look at it more closely, I wonder if I've configured something incorrectly on the NetApp. For example, if I enable a NIS domain on the NetApp, permissions (for both uid:gid) on the nfs4 mount start to work correctly for everybody. Unfortunately, we're trying to end-of-life NIS, so using NIS is not an option. I verified that my nfs.v4.id.domain and domain in imapd.conf are the same. Does anyone have other suggestions for me to consider? Thanks! -- Nate

Tracking Space Trends on NetApp Filers
by Daniel Keisling 17 Dec '07

17 Dec '07

Hello, Are there any utilities/scripts out there that will keep track of storage trends on NetApp volumes? I'm in need of something that will show how much volumes have increased in space utilization over time. My first guess was just simply do 'df' RSH commands and parse/store the data, but I'd like to know if there was anything more robust before I began.

Oracle on Netapp
by Page, Jeremy 16 Dec '07

16 Dec '07

Looking for someone out there with some experience with pSeries + Oracle. Is SnapVault, SnapMirror, Snapshot used as common replication tools for Oracle in the General Public versus native Oracle Replication or Snapshots? Long ago we also looked at Native clustering / replication tools at the P-Series level. Just curious on how many companies use the SAN replication tools for Oracle. I'd appreciate any insight you might have and I'll try and do some research on this. From a storage admin side I was assuming it's as simple as creating a shell script that quiesces Oracle, takes a snapshot and then lets Oracle move on with it's life, am I missing something? -Jeremy This message (including any attachments) contains confidential and/or proprietary information intended only for the addressee.

RE: Snapmirror initialization aborts consistently
by Mike Partyka 14 Dec '07

14 Dec '07

Yes, although it from the source logs you can see it doesn't hang in the "exact" same place it's always around 83G transferred. I reconfigured the VSM to a QSM this morning since it's really just qtree tree1 in the flexvol and it hung even sooner, at the 65G mark. I'm trying to get downtime to run wafl_iron at this point. I just don't know what else to do. -----Original Message----- From: Mailing Lists [mailto:mlists@uyema.net] Sent: Wed 11/7/2007 12:06 PM To: Mike Partyka Cc: NetApp Toasters List Subject: Re: Snapmirror initialization aborts consistently It isn't clear whether you tried initializing again where it left off.

Aggregate shows need check
by Bryano 14 Dec '07

14 Dec '07

Hi, We have recently upgraded to 7.2.3 and have created an aggregate containing 2 flex volumes however I have recently noticed that the status of the aggregate shows 'need check'. According to the manuals this means that i need to run a wafl consistency check ran on it (Wafl_check), can I do this while the filer is online and serving data or do i have to boot the filer in to maintenance mode?. If i was to delete the aggregate and start again would I take it that would negate the need to run the wafl_check? reason I ask is that the volumes only contain test data and this is more feasable than bringing the whole filer down for several hours (its an R200) Thanks -- View this message in context: http://www.nabble.com/Aggregate-shows-need-check-tf4942880.html#a14149910 Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

traditional SnapVault destination vol to flex vol convertion question
by Bob Doho 11 Dec '07

11 Dec '07

Hi guys, We need to convert traditional SnapVault destination volume (2TB) on a R200 to flex volume. We want to keep the snapvault snapshot to avoid doing another base transfer from source located in another data center. VSM is not possible. QSM will not copy the snapshots. We have heard that there is a procedure with snapmirror –s options that do the trick. Can someone help us with that procedure? Many thanks in advance. Thanks,
