Syncsort backup express and Hitachi GF920
by John Files 30 Mar '06

30 Mar '06

Hi, Anyone out there using Backup Express successfully? We have a rather strange problem: Copied all user data from our old F740 to the GF920 HDS (used both cp and ndmpcopy in separate tests) I am able to mount from the GF920 via nfs and see all the data.Likewise with a CIFS share. When I use Backup Express to browse the copied data it doesn't see all the files I can see via CIFS/NFS. Various dirs are missing,apparently at random.Therefore it can't perform a valid backup. Anyone got any ideas? John -- John Files <jhf(a)dmu.ac.uk>

Chaps I am about to finally leave my NT4 domain for the brave new world of Win2K3. I have FAS3020Cs and would like to know of any gotchas I should be aware of. Any GPO settings Local Groups That sort of thing. I have done some research but haven't really thrown up any information.

RE: snapinfo -- exchange on netapp
by Glenn Walker 30 Mar '06

30 Mar '06

Jochen - hard to say. The argument for putting everything on one massive aggregate is so that you have the performance you need with the existing disk capacity (vs having multiple aggregates\volumes each with their own parity disks). However, planning for failure, it is possible but very unlikely for an aggregate to go offline due to some sort of failure. That being said, you might lose the filer itself during a disaster. The documentation states that everything should be in a separate volume, and sites Microsoft as stating this. Undoubtedly, MS states this for DR reasons, while NetApp states it for issues with snapshots (and with tradvols, for DR reasons). After giving this much thought, my recommendation would be one huge aggregate with multiple volumes - it gives you the performance you need without wasting disks. If you really need to worry about DR, then RAID-DP and SnapMirror are the right solutions (to prevent failure and to deal with failure when it happens, respectively).

ToasterView + Big volume support
by jeff.mery＠ni.com 29 Mar '06

29 Mar '06

I'm currently playing with ToasterView (http://www.cuddletech.com/code/toasterview/index.html). It looks like something we'll want to run with, but I've hit a snag. ToasterView uses the deprecated dfTable values in the MIB to pull volume sizes. This is okay for volumes less than 2^31 KB (~2TB) in size. In fact, everything looks good for volumes under this on our systems. However we have one volume on each head greater than 2TB (one is 3+ and the other is ~4). My problem is this: NetApp implemented new MIB values to address this issue. There is now a high and low value representing the high-order and low-order 32 bits of a 64-bit number. Has anyone modified ToasterView (and Toasterview_rrd) to use these new values and support volumes > 2TB in size? If so, would you be willing to share the code (or appropriate snippets)?

RE: cifs username to map as a domain\username
by Glenn Walker 29 Mar '06

29 Mar '06

I fear your options may be limited. I know little about the Ricoh product, but would suspect that they have documentation on getting this to function in a domain (any domain). I would also suspect that you would need to create a machine account for the printer in the domain to enable this functionality, but I could be wrong. A quick search turns up some promising evidence of this, but I do not know your specific device type. I'd definitely recommend a healthy dose of 'google' before continuing too deeply here... Barring the above, I fear that the passthru authentication may be your only hope, specifically given the fact that the device does not prepend the username with a domain (at least not correctly). One thing that would be immensely helpful: a snippet of the cifs trace login info and perhaps a packet trace to help understand exactly what is going on. At this juncture, you may be wary to share this information with the 'group' here (and the rest of the world as the data is archived on a web-host somewhere) - I'd recommend opening a case with NetApp support if packet trace is the only path you can take.

If it doesn't have a machine account in the domain, then it's not going to do KRB authentication because it won't be able to get a ticket (no SPN, no ticket). As far as that goes, even NTLM would likely cause problems. With what little information I have, I'm tempted to recommend looking into the 'passthrough authentication' portion of the ONTAP documentation - it should do the trick and allow you to authenticate (though you'll be creating an account on the filer via useradmin user add).

A domain account has been setup for this user ID for access and is permissioned on the filer both for share and folder access. The ricoh setup does not have a separte entry for domain and user name so I'm getting them to DOMAIN\username but when the filer sees the attempted login it domain\username where normal users the filer sees them as DOMAIN\username. I assume that the filer is seeing the ricoh username as just that a username, instead of a Domain nad Username.
