RE: Automatic NFS export on vol create

FAS940 with 144GB drives

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
by PAOLO FRANCO 12 Aug '04

12 Aug '04

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.

NDMP & NetBackup 4.5FP6 restore problems
by John Stoffel 12 Aug '04

12 Aug '04

Hi folks, Has anyone else run into problems restoring data from NDMP backups? We've got a NetBackup v4.5FP6 (recently upgraded from FP5) setup, with one master and one media server. Both are Sun V880s running Solaris 5.9. We have an ADIC I2K library with six LTO2 tape drives, one of which is dedicated to NDMP backups. We have six filers currently doing NDMP backups running various levels of Data OnTap. Mostly 6.3.1R1, though we've got one that's been upgraded to 6.4.5 for testing, and one still running 5.3.7R3D12 (which I know I need to upgrade...) The problem is that restores kick off just fine, the metadata is all restored (though with Dec 31, 1969 as the date) but then it just bogs down and stops restoring data. Eventually it times out and we get an error 5 in NetBackup. We've even tried restoring data from a 6.3.1 client backup to the 6.4.5 toaster, in case it was a problem with the restore end of things. No luck. Any hints would be appreciated. John John Stoffel - Senior Unix Systems Administrator - Lucent Technologies stoffel(a)lucent.com - http://www.lucent.com - 978-952-7548

Linux, automount and filer
by Goebel, Uwe 11 Aug '04

11 Aug '04

Hi folks, I'm not sure if this is something for the list, but maybe someone run into the same issue. When I use automount from RedHat Enterprise v3 or Suse9 to the filer (cd /net/filer/vol/vol0) I got a message 'No such file or directory', as you get, if the path is wrong. Well, that isn't the case, because when I use it from a Sun and HP it's working fine. I installed autofs V4. In auto.master I enabled auto.net, otherwise it wouldn't do. Has it to do with the automount options? I use the standard options (opts="-fstype=nfs,soft,intr,nodev,nosuid") Or should there be something set on the filer side? Your ideas are welcome. Cheers, Uwe

FTP on new Filer
by Steve Evans 10 Aug '04

10 Aug '04

I'm trying to setup FTP on a new Filer and I'm running into some issues. My version of ONTAP is 6.5.1R1, it's a CIFS only environment. My options ftpd.auth_style is NTLM My options cifs.home_dir_namestyle is mapped If I have cifs.home_dir_namestyle set to ntname everything works fine. All we use home directories for is FTP'ing though, which is only done by some service accounts. So I'd like to use mapped namestyle and set home directories on individual accounts. So in my passwd file I have a line sevans::10:10:Testing FTP:/vol/vol0/test: My usermap.cfg file has DOMAIN\sevans == sevans Now shouldn't that work? When I try to ftp in I'm told 530 /: Login incorrect - User has no home directory. Login failed. Steve Evans SDSU Foundation

RE: cold head swap or temporary cluster finangle?
by jeff.mery＠ni.com 06 Aug '04

This would require downtime on the existing system unless it already has cluster hardware installed. It may even require downtime if the hardware is already there, but I'm not sure. Can anyone provide any insight here? If the hardware isn't there, you'd have to down your existing filer, install the cluster interconnect card, cable it to the new head, bring the original up, license clustering, setup the other system for clustering, .... I'm sure you get the idea =). I would probably choose the 10 minute head swap.

I have not seen this. We have thousands of clients on multiple filers. In our experience, "missing" files are either because it was deleted or someone moved it.

As explained yesterday I'm going to email you my questions/concerns about the exchange questions I had. Currently we have are exchange 5.5 DB and logs on our FAS250, the logs and DB are on separate Vol. When we did a performance test yesterday on the FAS250 it did not appear to be working hard, at times we did see a spike, but for the most part the system was running below a high stress margin. The exchange DB is on the same Vol that houses a CIFS share and this share is the Home directory for a lot of users. We are planning on moving this data to a separate Vol so that our exchange DB doesn't have to compete for access time and possibly get bogged down by this CIFS share.

Don't forget about host file entries. Name resolution won't be available on the private interfaces, so both the Exchange box and FAS will resolve each other over the public interface. This will return IPs from your public network so they'll continue to talk over that interface. You can get around this using host files to force both the FAS and Exchange box to use the private interface. %SystemRoot%\drivers\etc\hosts for NT /etc/hosts on the filer The format is <ip> <some_white_space> <hostname> for both files. I would play it safe and add entries for both then NetBIOS name and FQDN.

Zeroing out disks

Does anyone know how you can zero out a specific disk(s) ? The "disk zero spares" command or "spares_zero" diagnostic command seem to zero out ALL spare disks only. Thanks, George

Disappearing Files

We are using the Dave Client (CIFS client for the Mac) to connect our Macs to a F960 running Data ONTAP 6.5 Every now and then we get reports of files disappearing and most of the time it is due to the user error, but that doesn't explain all of the complaints. Has anyone ever seen or heard of files disappearing and then reappearing. Thanks Jack This email and its contents may be confidential.

Hi Geoff, The following KB article tells you what can cause this error. (it also tells you how to disable the redirector - do not do this). Microsoft Knowledge Base Article - 163401 - http://support.microsoft.com/default.aspx?scid=kb;EN-US;q163401 Anyway this points it to a networking issue. Some things to check: 1 Network card Auto/full/half 2 Switch/hub (I hope they do not have a hub :)) set to auto/full/half You should also run a netdaig from the filer as this may tell where the misconfigured network device may be.
