RE: One more netbackup question...
by Joe Luchtenberg 10 Apr '02

10 Apr '02

DISCLAIMER: Non-engineer speaking -- alarm bells should be ringing... It was my understanding that CIFS will preserve standard Unix Read/Write/Execute file permissions. However, does the filer even support Solaris ACLs? Not sure which other flavors of Unix have similar features (at least AIX does, and I would suspect essentially all do; different implementations, though). Previously ONTAP did not support Unix ACLs, because of their diverse implementations. However, I thought newer versions of NFS were supposed to address this. What's the current status of ONTAP support for Unix ACLs? If Unix ACLs are supported, then are they preserved, too? TIA. Joe Joe Luchtenberg Dataline, Inc.

One more time? I have been told that backing up over CIFS will preserve UNIX permissions (see: http://www.netapp.com/tech_library/3052.html) I stand corrected!

Most of what you say is correct, but Ontap 6.0 and greater supports DAR, due to NDMP allowing for cooperation between NDMP client and NDMP server.

Can I watch/check progress of reconstructs?
by Ben Rockwood 10 Apr '02

10 Apr '02

Hello Toasters. I've got a volume that is reconstructing, but I would really like to be able to make estimate on it's time of completion. Generally just a "blah blocks out of blah done" works, since I can do the math to make a logical rough estimate as to the completion time. All I know to do for status during a reconstruct is to use vol status. Is there a better more verbose way that can be issued at will? I suppose you can just watch syslog too, but I'd prefer a command. Btw, I'm open to using a SNMP OID to get the info too, if I knew which IOD is was, and I don't recall any IODs that would tell me. Thanks! brockwood(a)homestead-inc.com

hi, has anyone ever seen secureshare access not be able to get permissions for a dir or file? it works thru a cifs drive mapping, but if i use it against a drive mapping created with sun's pc nfs client it comes back with: "Couldn't get permissions for file \\filer\...." or Z:\xxx\europe>cmdntapperm . ---------- 1 4096 04/08/2002 12:10 PM with cmdntapperm. perms are visible from a unix host that has the filer mounted. i suspect it is a problem with the sun client, but it's all we have so i wanted to know if anyone had similar problem. ontap 6.1r1, qtree is unix style. -- thanks.

RE: NT file permissions lost on shares after logout

We've had much success using robocopy version 1.95 available in the Windows 2000 Resource Kit. From the console of the source NT 4 or W2K server, map the Z:\ drive to the appropriate destination volume on the filer. To avoid fragmentation, move the data in two steps -- The /CREATE switch creates a directory tree structure containing zero-length files only. The second pass actually copies the data to the destination. The /SEC switch preserves NTFS permissions. Here's an example . . . PASS ONE robocopy "F:\folderA" "Z:\Accounting_TOP\folderA" /E /SEC /CREATE /R:3 /W:1 /V /LOG:folderA1.TXT PASS TWO robocopy "F:\folderA" "Z:\Accounting_TOP\folderA" /E /SEC /R:3 /W:1 /V /LOG:folderA2.TXT -----Original Message----- From: Wurster, Richard M DSTI [mailto:rick.wurster@SBCCOM.APGEA.ARMY.MIL] Sent: Tuesday, April 09, 2002 11:48 AM To: 'Kitch, David'; 'Pucky, Todd M.'; toasters(a)mathworks.com Subject: RE: NT file permissions lost on shares after logout Definitely Secure Copy (Small Wonders Software) does the job.

6.2 ?
by Frank Bonnet 09 Apr '02

09 Apr '02

Hi I'm planning to upgrade our F85 to 6.2 we are running 6.1.1R2 for now. The filer is mostly used for NFS services but we are planning to progressively use also CIFS Do I have to expect "bad" surprises with 6.2 ? Does it carry significant progress for CIFS use ? Any infos welcome. Thanks a lot. -- Frank Bonnet
