RE: ontap 6.0 only 350 cif-sessions?
by Bagg, Rod 26 Sep '00

26 Sep '00

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 are taking immediate action to understand the root cause of why this bug was not discovered internally and correct the situation.

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. Symptoms of the problem can be client session disconnects, hangs or very poor CIFS performance. A 'cifs stat' would typically show the counter named 'Max pBlk Exhaust' to be a very high number - 100,000s or more. We have identified the root cause of this problem and have developed the fix which is currently undergoing QA and load testing. ONTAP release 6.0R1 is tentatively scheduled to be released by the end of this week to resolve this bug.

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. We turned off disk scrub on the F760's because it really impacted user file access. I was told this issue would no longer be a problem. Well, it takes the F840's, each with 12 shelves of 36 gig drives, from 1AM to 2PM (yes, 2 PM) to scrub under very light load.

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.
