There was a patch posted to this list a while back. If anyone can't find in the archives, drop me a note and I'll send it along. It works really well (we replaced our default install of GNU find with a patched version because it works so well). Peace, dNb

RE: Source for a non-root quota program?

In the "Tools & Utilities" section of the NOW (http://now.netapp.com) site, in the "Toolshed" area, you'll find a "quota_tools" entry. That package contains several utilities for quotas, including a perl script named netapp_quota_report that will talk to a NetApp Filer via rsh, get a quota report, and construct an HTML web page. You can specify a quota limit, and people over that limit will be highlighted in red. *NOTE* - Be sure to use the "-ontap 5" option to netapp_quota_report, if you are using ONTAP 5.0 or higher. The quota_tools package also contains some scripts for sending mail when quotas are exceded. The package was written by Ed Finch (efinch(a)vais.net). ...Tim Thompson...Network Appliance, Inc...tjt(a)netapp.com...

If you're storing CIFS data, you'll of course lose it. Dump and restore should still work, if you want to do that; you can even do it by rsh over the network rather than go through a tape. >Doing a plain 'cp' tends to skip over .* files and is a bit tricky about >retaining permissions.

Invariably, I will get a stale NFS error and eventually time out. Typically, I like to cd to the directory in question and use: find . -print | cpio -pdumv /destination/directory But this will choke on filenames with spaces in them. >Is there any way getting past the .snapshot directories during copies?

You can get around it by copying each subdirectory from the root mountpoint individiaully, or using a find option to prune .snapshot (check the man page). Bruce

I would think the rsync program (which is what we used to take our data off Sun and Auspex boxen and put it *on* our filer) would be a good choice. We also use it daily to backup local data from our main data servers on to our netapp prior to moving the data to tape. It is a really good tool. Rsync has options to exclude certain files/dirs which I suspect could easily be used to tell to ignore snapshots (though I would tend towards hiding them as another person suggested). Rsync can be found at: <http://samba.anu.edu.au/rsync/>. Peace, dNb

RE: "ypset" needs added to common command set
by Hackworth, Brian 19 Oct '99

19 Oct '99

: I would like to see the "ypset" command added In a forthcoming update release for 5.3, there is a new option to allow you to specify the list of NIS servers the filer should try to use (or "*" to use the old broadcast method). This obviates most of the need for ypset. In the next major functionality release, the family of yp commands are moved out of "rc_toggle_basic" into the main OnTap command set. As an engineer, I'm not allowed to suggest any dates for these releases. - Brian Hackworth

Hi, NIS has been revamped in Data ONTAP 5.3.3 ( which is a special release available upon request). This supports multiple preferred NIS servers. All these are available in the soon to be released Data ONTAP 5.3.4.

That is interesting indeed. I couldn't find a mention of this on NOW or NetApp's main site. Perhaps it's there and I simply didn't use the right keywords in the search. As I understand it, modern NetApps use 32-bit inode numbers. This gives us 2^32 inodes. 32 million is roughly 2^25 that is 2^7 times less than alegedly supported by the inode numbers. 32 million is a far cry from roughly 4.3 billion supported by 32-bit addressing. Furthermore the new NetApp hardware is 64-bit which makes far larger addresses possible. Tom

There has been an open bug/RFE on this since before NIS was even released. :) There was some talk recently on the list about them revising their approach to some of these commands but I didn't see a firm date set.

Easiest way to migrate data off of Filer
by Yicheng Li-R37424 19 Oct '99

19 Oct '99

Hi, We're running an F540 with Ontap 5.3.2D3, setup for NFS and CIFS services. Most (~95%) of our NFS clients are Solaris 2.6 machines. I would like to know if there is an easy way to migrate home-dir data off of the filer and onto a Sun server (Enterprise 450 with Solaris 2.6). Doing a plain 'cp' tends to skip over .* files and is a bit tricky about retaining permissions. We also have a script 'copy_dir' that uses the copy_io command, but it takes an extraordinarily long time. We're talking a 6 Gb home directory taking more than 12 hours to copy (over a 100 Mbs connection, too). I am sure that there is no problems with the network, and I suspect that the copy_io is getting hung up trying to copy over each version of the .snapshot directories. Invariably, I will get a stale NFS error and eventually time out. Is there any way getting past the .snapshot directories during copies? I imagine that other Solaris admins must have run into this problem before. ---------- Yicheng Li (480)413-6636 WISD Engineering Network
