RE: OPLOCKS

From my experience, don't use oplocks - it tends to do more harm than good. Just do 'options cifs.oplocks.enable off' Alex. -----Original Message----- From: stefan.holzwarth(a)zentrale.adac.de [mailto:stefan.holzwarth@zentrale.adac.de] Sent: Wednesday, May 29, 2002 11:54 To: toasters(a)mathworks.com Subject: OPLOCKS Hi, since we have some small instabilities in our network ;-) it sometimes occures that a oplock isn't released by a NT Workstation. I have then to do manually a cifs terminate for that PC. Is there another way to do that? Shorter timeouts for automatic break by the filer? Why does the filer not recognize the situation - the new cifs session from that rebootet NT workstation (we use 6.1.2 R1) Thanks for input Stefan Holzwarth ---------------------------------------------------------------------------- -- Stefan Holzwarth ADAC e.V.

RE: True 64 UNIX and Filers
by Ben Rockwood 29 May '02

Absolutely NOT. Toaster's are for Network attached storage, NOT local disk. A quorum device is, as you state, a disk which is connected to both nodes, but must be direct attach via SCSI (whether the medium is SCSI or FC doesn't matter). A network device may not (and SHOULD not) be used for quorum. Your quorum device should be the closest, simplest and most robust disk (preferably) avalible. If you review your documentation for your cluster implementation, you'll find that you need to supply it with a SCSI ID, which a Filer would not be.

So it must be external storage. Usualy someone would suggest SAN, but i'l like to set it up wit Filer. ----- Original Message ----- From: "Ben Rockwood" <BRockwood(a)homestead-inc.com> To: "Uros Lampret" <netapp(a)ourspace.si> Cc: <toasters(a)mathworks.com> Sent: Wednesday, May 29, 2002 7:50 AM Subject: RE: True 64 UNIX and Filers In what regard?

very serious NFS bug
by Igor Schein 28 May '02

28 May '02

Hi, I came across the following bug. NFS writes from Redhat 7.3 client result in filer giving a lot of RPC timeouts for all other clients on the network. Here's a link describing what's known about this bug so far: http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=65069 With default wsize value of 15K, tcpdump shows a lot of fragmentation packets. While it's obvious that it's RedHat 7.3 bug, I am still wondering why NFS v3 is vulnerable to such sort of DoS attack. On related note, I looked at registry file on the file, and I found these entries: options.nfs.tcp.recvwindowsize=26280 options.nfs.tcp.xfersize=32768 options.nfs.udp.xfersize=32768 Is the 1st one only applicable to NFS over TCP? Is the last one read-only? Thanks Igor

RE: Accessing a share from DOS.
by Asbjørn Bjørkelund 28 May '02

It's possible to access the filer from a dos 6.22 boot floppy, but i guess your problem is related to the lan manager version on your boot floppy, it should be at least lan manager ver 2.2c, i had the same problem as you are experiencing now i solved it with downloading boot floppies from either www.bootdisk.com or www.nu2.nu/bootdisk/network/ then i got a lan manger version that was working ok with the filer.
