RE: Automatic NFS export on vol create
by Mike Sphar 18 Aug '04

18 Aug '04

Speaking purely for myself, as a long-time Sysadmin, the fact that so much of Netapp's config is stored in text files was a *big* advantage to me. Databases always seem like a good idea until they get corrupted, or the front-end administration tools fail because of bad data. (Anyone else ever adminned AIX? Hell, just the other day I had to spend a fair amount of time trying to repair a corrupted registry on a Windows box.) -- Mike Sphar - Sr Systems Administrator - Remedy, a BMC Software Company -----Original Message----- From: Haynes, Tom [mailto:thomas@netapp.com] Sent: Wednesday, August 18, 2004 1:04 PM To: skeezics(a)selectmetrics.com Cc: toasters(a)mathworks.com Subject: Re: Automatic NFS export on vol create Is it a dumbing down or an automation of common steps? I know when I designed and coded the automatic writing of the /etc/exports, my goal was to remove some repetitive and manual steps. You have to remember that is what programming is all about: 1) finding common blocks of functionality and wrapping them in a function. 2) reducing the human interaction. Some of the posters on this thread make it sound like this was a conspiracy. If we had been a brand new company and we came out with a product which kept the exports information in a database instead of a flat file, would you have been this upset? Or would you have enjoyed the experience? I've been of the flat file bent myself for a long time. Now that I have to maintain the exports file, I'm leaning towards a database for it. There is just too much ambiguity in parsing entries in the host lists - well formed fields, like *shudder* XML, make too much sense. Anyway, there is no global plan to dumb down the product - just local designs to reduce problems found in customer escalations. > On Wed, 18 Aug 2004, Bruce Arden wrote: > > Uh, whoops, now I've got this "/vol/new" export at the end of the file? > Hmmm.

any other gotchas for 6.5.x export files
by Kerry Herschel 17 Aug '04

Hi, I am about to upgrade to 6.5.x from 6.4.2P11. Are there any other gotchas about the exports file in 6.5.x?

Agreed... Making it an option would be a much cleaner solution. It's all these changes/weirdnesses etc. that is causing me to not even consider moving to the 6.5 series yet. I plan on staying with 6.4.x for quite a while longer, until the rest of the changes/bugs/etc have been found and ironed out. Davin.

In addition, when you do a volume name change, the OS will quietly change the exports file to what it thinks you'd like to have there. I feel it's rude to make those changes to MY export file without letting me know. NetApp says they are making it easier for system administration for less experienced owners.

How to restrict an NESS share to user

Hi, How can I restrict an NFS share to certain users only? I cant see a parameter in OnTap's NFS that would allow this, unlike standard nfs where I could easily do this. Any ideas?

FAS940 with 144GB drives
by Michael Haller 13 Aug '04

13 Aug '04

We're looking at a 940 system and have been quoted for one with 144GB drives. I'm a little unsure about the use of 144GB disks with repect to performance but don't have access to any data to support this. Does anybody have relevant links or any other comments? - Michael

We have an F940c cluster. There are 2 shelves of 144 GB disks configured in a single volume on each head (4 TB raw per head). These systems are used as big file servers with CIFS-only traffic. We've had them in production since 11/2003 and haven't had any performance issues at all. However, we're not doing DB work or NFS traffic (NFS coming soon). There are also no iSCSI connections. Like I said; just big file servers...but no performance issues at all.

re.co

What I wish to relate to you will smack of unethical practice but I want you to understand something. On June 6, 1999, Mr. Richard Smith came to our Bank to engage in business discussions with our private banking Division. He informed us that he had a financial portfolio of 5.7 million USD, which he wished to have us turn over (invest) on his behalf. Based on the investment, we spun the money around which with accrued profit and interest Stood at over 6.5 million United States Dollars.In mid 2001, he asked that the money be Liquidated because he needed to make an urgent investment requiring cash Payments in Antwerp. He directed that I liquidate the funds and Have it deposited with a firm in Brussels. I informed him that Banca de san paolo would Have to make special arrangements to have this done and in order not to Circumvent due process; the bank would have to make a 9.5 % deduction from The funds to cater for banking and statutory charges. He complained about The charges but later came around when I explained to him the complexities Of the task he was asking of us. Cash movement across boarders has Become especially strict since the incidents of 9/11.I contacted my affiliate in Brussels and had the funds available in main land Europe. I undertook all the processes and made sure I followed his precise Instructions to the letter and had the Funds deposited at the UK based security Consultancy firm.Mr. Richard. Smith told me he wanted the money there in anticipation of his arrival from Norway later that week. This was the last communication we had, this transpired around 25th February 2001.In June later year, we got a call from Uk based firm informing us about The inactivity of that particular portfolio. This was an astounding position as far as I was concerned; given the fact that I managed the private banking sector I was the only one Who knew about the deposit at Uk based firm and I could not understand Why Mr. Richard. Had not come forward to claim his deposit. I made futile efforts To locate Mr. Richard no success, Four weeks later, information Started to trickle in, apparently Mr. Richard Smith was dead. A person who suited his description was declared dead of a heart attack in Cannes, South of France. We were soon able to identify the body and cause of death Was confirmed. The bank immediately launched an investigation into possible Surviving next of kin to alert about the situation and also to come forward To claim his estate. I Mr. Richard Smith died in testate. This bank Has spent great amounts of money trying to track this man?s family; they have Investigated for months and have found no family. The investigation has come to an end. My proposal; I am prepared to place you in a position to instruct Uk Based firm to release the deposit to you as the closest surviving relation. Upon receipt of the deposit, I am prepared to share the money with You in half. That is: I will simply nominate you as the next of kin and have them Release the deposit to you. We share the proceeds 50/50. I would have gone ahead to ask the funds be released to me, but that Would have drawn a straight line to me and my involvement in claiming the deposit. I assure you that I could have the deposit released to You within a few days. I will simply inform the bank of the final closing of The file relating to Mr. Richard. I will then officially communicate with Uk based firm and instruct them to release the deposit to you. With These two things: all is done. The alternative would be for us to have uk based firm direct the funds to another bank with you as account Holder. This way there will be no need for you to think of receiving the Money from Uk We can fine-tune this based on our Interactions. I am aware of the consequences of this proposal. I ask that if you find no interest in this project that you should discard this mail. I ask that you do not be vindictive and destructive. If my offer is of no appeal to you, delete this message and forget I ever contacted you.

cold head swap or temporary cluster finangle?
by Tavis Gustafson 12 Aug '04

12 Aug '04

I have an F760 I need to swap out with a new F760. A cold swap would only cause 10 minutes of downtime, but it would be cool setup a temporary cluster and do a takeover with no downtime. How feasible is this? Would setting up the cluster situtaion mandate a reboot of the filer in question anyway? -tavis New Dream Network
