Bruce, I called it "folklore" because I was told about the supposed improvement in disk scrub speed by a couple of Netapp engineers at a recent engineering meeting I attended. Maybe it would have been better to say "from unofficial sources, in a casual conversation, sharing afternoon drinks at a Netapp event". The reconstruct speed is set at the default of 4. The 2 systems are very lightly loaded from a user traffic standpoint, cpu load at under 10% during reads and bursting to 20% during WAFL writes. There are 5 minute periods every 30 minutes when the cpu goes up to 95% during SnapMirror operations. Until there is considerably more user traffic on the F840's, I will not be able to ascertain user impact. My main comment was about the total time to do the scrub. Of course, time isn't the key factor - impact on user file activity would be much more relevant, and I don't have numbers for that yet. -----Original Message----- From: Bruce Sterling Woodcock [mailto:sirbruce@ix.netcom.com] Sent: Monday, September 25, 2000 6:36 PM To: Sam Schorr; 'Todd C.

Various load, configuration, and performance testing and analysis were done at length on ONTAP 6.0 before its release. Unfortunately we can't catch all bugs in every possible scenario.

We have identified bug 30873 which can impact CIFS performance in ONTAP 6.0 when the number of active CIFS sessions on a filer exceeds 200.

A 'cifs stat' would typically show the counter named 'Max pBlk Exhaust' to be a very high number - 100,000s or more.

Good news! I was incorrect in stating that volcopy/Snapmirror would not work. this information came through a misunderstanding, and has now been clarified. I am very, very pleased to be corrected on this as it makes our migration strategy in upgrading from some older F760's with 9 gig drives to the F840's w/36 gig drives a snap (pun intended). -----Original Message----- From: Mike Federwisch [mailto:mikef@netapp.com] Sent: Tuesday, September 26, 2000 8:40 AM To: Sam Schorr Cc: 'Todd C.

I would really like to hear where you heard that you cannot snapmirror or vol copy between 5.3.6H1 and 5.3.6. This should work just fine and we do different variations of this internally to netapp. Please let me know where you heard this so that I can find out why this rumor started and hopefully stop it from being propagated. If it really didn't work, I would expect a bug to have been filed and I haven't seem one complaining about this situation. Mike Federwisch Network Appliance Inc.

We have 2 F840's in production along side 12 F760's. The big "gotcha" for us is that you cannot volcopy or Snapmirror between 5.3.6H1 and the F760 5.3.6 O/S - really not so good in our case as I would love to use volcopy to migrate from the F760 to the F840. These things scream, but its early to compare as our load ramps up. One piece of reality-versus-engineering-claims relates to disk scrubbing.

tar against netapp NFS exported FS reports ACL errors?
by Herbert Kornfeld 26 Sep '00

26 Sep '00

I'm running HP-UX 11 and mounting a handful of filesystems ovber NFS v3 from a filer. This is fine. The only fly in the ointment is that when I use tar to backup a small set of files, I get error messages like these: "optional ACL entries for </foo/bar/baz> not dumped" I understand that I can avoid these messages with the A switch to tar, but I don't understand what these ACLs are, how tar knows they're there and how they got set. I certainly haven't set any extra ACLs up -- I'm relying purely on the native rwx type permissions here. Can anyone enlighten me? --herb end _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
