RE: SGI mail issues on Filer

Hi Chris Lamb wrote: > Not to pick on you, Graeme, but I just cannot believe > that almost TEN YEARS LATER that this belief that "NFS > is bad for mailboxes" persists. OK, I'll add the caveat that in _my experience_, NFS is bad for mbox or other file-based mailbox formats in situations where there are multiple NFS clients (read: SMTP, IMAP and POP servers in a load-balanced farm) doing simultaneous delivery and client reads via IMAP4 or POP3. To expand a little, I've personally never deployed a single production mailbox on an NFS backend where there weren't multiple frontends in use! > We solved it a decade ago, folks... true, NFS locking > has never been easy or pretty, but with care it could work. > Perhaps with NFS v4's locking support people will finally > start to reevaluate those old NFS prejudices? Hrm... on a personal note this is about the only NFS "prejudice" I have - and you've now blown it out the water ;-) > Just one fairly nasty side-effect of maildir format on > filers: the 4K block size. I'll keep an eye on that. Thanks. Graeme

Toasterview v0.2
by Ben Rockwood 11 Dec '04

11 Dec '04

Hey All. Several people asked me to report to the list when I released ToasterView 0.2, and here it is. You can download it and see a demo page here: http://www.cuddletech.com/code/toasterview/index.html (There is also a nifty image of it on the frontpage of cuddletech.com right now) I'm open to any requests or contributions to the code base. It's a pretty nifty tool. The new version adds an expansion module that leverages RRDtool to graph and chart the growth of volumes over time (1 hour, 6 hours, 1 day, 1 week, etc). It's a handy way to keep an eye on just how much is really changing and also can report when more change occurs in a given time period (namely 1 hour) than is sane. As always it's GPL so pass it around. :) benr.

Hi all First off, a small introduction: I'm the Hosting Development Engineer for PIPEX Hosting in the UK. I have a small interest (depending how you look at size!) in NetApp kit, in that we're running them for a number of different applications.

Certainly my > Qualcomm pop documentation says you mustn't use NFS. Using file-based (UNIX spool, mbox format etc) mailboxes over NFS is bad. Using directory-based, such as Maildir format where every message is a separate file, over NFS is eminently possible - I know of several instances of very large installations using exactly this setup. > Similar issues with mail delivery agents (am I using the > right term?) dropping mail into an NFS mounted directory (I use > sendmail). It depends on the format you're delivering - I've successfully used Exim 3.x and 4.x to achieve Maildir deliveries, with courier-imap (and POP) to allow users to read it. Hope that helps Graeme

DR for exchange 5.5
by SKIP HOFMANN 10 Dec '04

10 Dec '04

Hello all We are going through DR scenario for our exchange 5.5 server. The domain is NT, our DB and logs our on a FAS 250 on separate Vol, and we are running snap manager and netapp drive version 1.1 to create the snapshots and also setup the drive mappings to the filer so we can mount the database. My questions are #1 if the exchange 5.5 server has a hardware problem or an OS problem, what steps must we take to bring up a new exchange 5.5 server, and then point all the clients to the exchange box? If we bring up a new exchange box, do we have to give this server the same name as the old exchange box? Thanks very much Skip Hofmann Senior Network Administrator MCSE 2000 NT MCP+I TetraTech Skip.Hofmann(a)ttisg.com <mailto:Skip.Hofmann@ttisg.com> 949 500 5286 cell 949 608 5801 office

Hello filers fans The coming of Samba 3.x brings my ritual question :-) Does a samba 3 server will be identify as a windows PDC by Ontap and thus would be able to use CIFS connections from clients to Samba server ? Thanks a lot. -- Cordialement/Regards Frank Bonnet

Oracle Volumes
by rkb 08 Dec '04

08 Dec '04

Had a meeting yestarday with my DBA team. We were discussing going to production with RAC boxes. They want to distribute Oracle across 3 volumes, Data, Redo, Archive. They prefer small volumes in the neighborhood of 100 Gig espeically for the Data Vols since we own SnapRestore. We'll only put one Oracle DB on a data Volume. Surely though we won't need 100 Gig especially since we are stripping the Redo and Archive logs out of there. I have all 72 Gig drives and warned that a 2 or 3 drive Volume is probably too small a number of disks. We are not at 6.5 (yet) so we didn't discuss Double Parity but its certainly on my agenda. So I'm counting on 2 parity drives when we get there. So minimally they want a 3 disk volume for (2 parity drives) for Oracle. What say you all? Would you, are you putting the hot writing Redo logs on a volume with other stuff? How is contention for that Volume? I told them "think differently about NetApp". Its not JBOD... I told them to think about that 128 MB (we have a FAS940) cache as "your disk" and not to worry about how NetApp flushes those writes out to disk. Think large volumes not smaller ones. Does Data Fabric Mgr. help identify "hot disks"? Statit? TIA -Bob Borowicz

RE: Oracle Volumes

Hi Bob, Go for enough spindles. So go for large volumes and a lot of spindles. You can separate logs and data because the have a totally different behaviour, depending on the I/O load of that DB). Ontap 7g will solve your problem (you can give them small volumes and you can use a lot of spindles in your aggregate. But it's maybe to soon to go to 7g. This depends on your upgrade strategy and the risk that you want to take. DFM can indeed identify your hotspots. We use that, but we also use statit (with a shedulded task (rsh script) and put the results in our management system).

Associate
by Micheal H John 08 Dec '04

Dear Friend, I pray this email meet you in soundness of body and spirit. Am in search of a competent associate oversea who will carefully act as my front before I summit my financial report for the 4th quarter of the financial fiscal year 2004 to the board of directors of my bank. Am Michael John, , Regional Treasury Manager of HSBC. However ,am contacting you based on your reputation, and country of origin that will be attached to this project. As the MD of my branch ,I realized that $28million is not recorded by the auditor general in his compiled files. I have contacted you to assist in repatriating this money by filing for an affidavit of claim for it in accordance with the operational measures of HSBC in clearing a dormant account before I will summit my financial report for the 4th quarter for the financial fiscal 2004 to our firm board of directors in other for the funds not to be recorded in the report. HSBC guidelines stipulates that if such money remained unclaimed for over a period of 3 years with the account unserviceable (DORMANT) the money will be confiscated and this will happen in the next few weeks into the 4th quarter of the financial fiscal year 2004 if nobody comes for the deposited consignment. As you can tell that we are in the last quater of the financial fiscal year 2004. I now seek your consent to act as my front based on your country of origin, so that this consignment valued at US$28 million dollars can be paid to you as the beneficiary as I have secured from the probate by the virtue of my desk as the regional manager to approve of such affidavit of claim. And its base on my position that I am taking due advantage of to have the funds cleared by a foreign associate to act as the beneficiary of the $28million and then we can split the sum in ratio 70% for me to 30% for you. I guarantee that this will be executed under legitimate arrangement that will protect you from any breach of the law as the regional MD of HSBC. The underline course of my action is due to my retirement plan next year, and the firm holds no brighter future for me, and am a father of 5,hope you wont conceive the wrong thought of I not been loyal to my firm. For equity is not for the indolent ,but for the vigilant. Upon your response I will give you further information inclusive of our bank WebPage and with the needed documents that will present you as the beneficiary of the funds and I working from the inside will approve you as the beneficiary to the funds. With a longing grace ,looking forward to working with you. Michael John HSBC Regional Treasury Manager London Branch. NB Note that the onus of approving the funds rest on my desk and its on this edge that the transaction got the uniqueness of realization. ------------------------------------------ Este mensaje fue enviado usando ZONAiMail.

Re: move/copy iscsi luns between volumes ?
by Reinoud Reynders 07 Dec '04

07 Dec '04

I think that every iscsi lun has some hidden meta data. So you must use a copy procedure that also copy those meta data. Qtree snapmirror and ndmpcopy of the qrtee must do the job. Reinoud Uzleuven Belgium -----Original Message----- From: owner-toasters(a)mathworks.com <owner-toasters(a)mathworks.com> To: toasters(a)mathworks.com <toasters(a)mathworks.com> Sent: Tue Dec 07 17:55:16 2004 Subject: move/copy iscsi luns between volumes ? hi, is it possible to move/copy iscsi luns in a qtree to another volume, and to mount them on the same snapdrive client ? lun clone supports just cloning within a volume, as i found in the manual. ndmpcopy copies the qtree/lun to the other volume, but i cannot connect to it with snapdrive windows. the error message said: the specified virtual disk is in exclusive use on this or another host....... i checked the following: the source lun is unmapped the copied lun renamed source and destination lun are using different serials. but i cannot connect the lun.... do you know any other ways to do that ? thx hannes
