zero length files
by Darragh, Stephen J 05 Jun '03

05 Jun '03

Hello, Has anyone ever seen a problem where the filer showed zero length files? We had some problem (of course this happened while I was out) This appears to have happend while doing a restore to a 99% full volume, but I can't really know the exact sequence of events. Thanks Steve Darragh

PDC and filers ...
by Frank Bonnet 05 Jun '03

05 Jun '03

Hi list Folks I am facing a boring problem which would request some netapp gurus lights ... We use OpenLDAP as centralized authentication system with Samba for windows clients. We have two filers ( F85 & F87 ) to store users data.The first one is a NFS server to be used by students and professors , it runs in UNIX mode and is accessed thru Samba + NFS for windows clients, this works slowly, but it works. Now I want to setup a CIFS only filer for administrative people that only use windows, the problem is I have no **real** windows PDC as our samba servers are acting as PDC to our windows clients. The problem is it is IMPOSSIBLE to tell the filer to use the Samba PDC as it seems to require a real M$ PDC which I haven't. It is MANDATORY for us to keep our unique and centralized authentication system with OpenLDAP as we have several platforms that *all* use LDAP. ( Windows, HP-UX, Debian Linux, FreeBSD, Red Hat Linux ... ) The question is : what is the solution to make a CIFS only filer ? Does any of you has ever start an Active Directory server as a slave of the OpenLDAP master ??? Thanks for any info. -- Frank Bonnet Groupe ESIEE Paris

NVRAM defective?
by John Enger 04 Jun '03

04 Jun '03

Upon initialising disks my NetApp displays the following: NVRAM test failed! NVRAM offset 0x300040, wrote 0xfe7e8201, got 0x457e8201 Program terminated ok Is my NVRAM defective? Does anyone know where i can get by hands on some chips for my F330? I have 4 SIMM-like NVRAM-sticks in the cache-card, and 4 free slots. Does anyone have a system standing around for parts? Thanks for any tips! J.

RE: Log Entry [CIFSAuthen:CRITICAL]
by Alan McLachlan 02 Jun '03

02 Jun '03

Hi Steve, It looks like the machine SID registered in the DC is different to the local SID on the filer. i.e. someone has deleted the filer from the domain and then put it back in with server manager without re-running CIFS setup on the filer. Is it an NT4.0 or Win2K environment? What may have happened is that the DC may have crashed and then was restored using a tape backup that was from an earlier integration period. i.e. 1. Filer integrated as "Filer" and is allocated machine SID S-.....-2314 (shortened for readability) 2. For some reason later on "Filer" is removed and re-added. CIFS setup is rerun. This time it gets machine SID S-.....-5236 3. DC crashes, is restored from a backup that was taken when the filer had machine SID S-.....-2314. Whatever the reason, you will probably find there was some human intervention on the weekend :-\ -----Original Message----- From: Steve Evans [mailto:sevans@foundation.sdsu.edu] Sent: Tuesday, 3 June 2003 1:48 AM To: toasters(a)mathworks.com Subject: Log Entry [CIFSAuthen:CRITICAL] [CIFSAuthen:CRITICAL]: CIFS - Filer's security information differs from domain controller.

quota messages
by Piotr KUCHARSKI 27 May '03

27 May '03

Is it only me who is bothered by this: Fri May 23 17:12:52 CEST [quota.softlimit.exceeded:notice]: Threshold exceeded for user 22638, tree 0 on volume v Fri May 23 17:18:12 CEST [GbE-II/e8:notice]: uid 22638: disk quota exceeded on volume v. Additional warnings will be suppressed for approximately 60 minutes or until either a 'quota resize' is performed. While first message is quite right, the second one has "GbE-II/e8" instead of "quota.hardlimit.exceeded" or similar. I've contacted NetApp about this and they just stated "nothing to worry about, it is normal". p.

URGENT NEED OF A BUSINESS PARTNER/CONFIDANT
by maryam abacha 27 May '03

27 May '03

LADY MARYAM ABACHA ABACHA COURT GIDADO ROAD KANO - NIGERIA ATTENTION: I am lady Maryam Abacha, wife of the late General Sani Abacha,ex-military Head of State of the Federal Republic of Nigeria who died on the 8th of June 1998 of heart problems. I contacted you because of my need to deal with person/persons who my family and I have had no previous personal relationship. Since the death of my husband, my family had been subjected to all sorts of harrassment and intimidation with lots of negative reports emanating from the government and the press about my husband. The present Government has also ensured that our bank accounts are frozen and all assests siezed. It is in view of this that I seek your co-operation and assistance in the transfer of the sum of US$100Million only being the very last of my family fund in my possession and control. The Federal Government have seized all our properties and frozen all our accounts both local and international, but my only hope now is the available US$100Million cash, which I carefully packaged and deposited with a security finance company Abroad. My purpose of contacting you is for someone who after transfering the funds, will be able to invest the funds on my behalf till such a time when I will be free from my present predicament. Your benefit I can assure you will be very substantial. Please ensure to keep this proposal very secret and confidential for obvious reasons and send to us your private telephone and fax numbers for easy and confidential communication. We await your immediate response. Sincerely yours, LADY MARYAM ABACHA ___________________________________________________ GO.com Mail Get Your Free, Private E-mail at http://mail.go.com

RE: APC UPS Monitoring
by Hill, Aaron 25 May '03

25 May '03

We had a "real" power outage with our F880 when the whole Datacentre lost power and the UPS freaked out for some reason. The F880 handled it perfectly. We had Sybase databases running in production at the time and when power was restored, they came up fine, now problems at all. I don't think that even a dbcc had to be run to clean the db's. Wish I could say the same for our old LSI/Metastor direct-attach SCSI. Took hours to get those monsters sorted out!

We had a F720 in a site that had regular power problems. At times every weekend the power would be down for more than an hour which would drain the UPS and the filer would fall flat on it's face. As far as the filer was concerned, there were no problems. On occasion the virus scanner servers would not reconnect on their own though. -Josh -----Original Message----- From: Andrew Siegel [mailto:abs@blueskystudios.com] Sent: Friday, May 23, 2003 11:03 AM To: toasters(a)mathworks.com Subject: Re: APC UPS Monitoring As far as I know, NetApps can survive a power cut without a problem.

RE: Folder update time
by Alan McLachlan 23 May '03

23 May '03

Hi Chris, I had assumed that atime was stored in the directory entry itself (which would have a pointer to an inode that was a simple list of data blocks), which would have explained the behaviour reported by Jeff Burton in his post. TR2002 ("Filesystem Design for an NFS file server appliance") doesn't specify anything about directory entry contents. The testing you show below seems to nails it, but I will go and have a play when I get a moment just fo see it for myself. Now, even if the directory entry doesn't contain the attributes but is simply a name with a pointer to an inode that contains the file attributes, a change in the file attributes will still require the pointer in the directory entry to be changed to point to the new inode. (WAFL NEVER makes changes to existing inodes, it always writes new ones). Therefore the block containing that directory entry will still need to be rewritten (you seem to imply that it won't). If you are at least partly right it would mean that OnTAP is deliberately ignoring the change to directory entries in order to appear more consistent with traditional filesystem behaviour. This still doesn't help us solve Jeff's problem... -----Original Message----- From: Chris Thompson [mailto:cet1@cus.cam.ac.uk] Sent: Friday, 23 May 2003 12:48 AM To: amclachlan(a)asi.com.au Cc: toasters(a)mathworks.com Subject: Re: Folder update time Alan McLachlan writes: > > A write to a file will change the file size attribute in the directory > entry, which will of course change the mod time on the directory itself.

RE: Folder update time
by Alan McLachlan 22 May '03

Steve, Jeff, A write to a file will change the file size attribute in the directory entry, which will of course change the mod time on the directory itself. In fact, if you don't have "atime update" turned OFF, even opening a file will change the directory mod time since the access time attribute for the file needs to be updated in the directory entry. Remember, in WAFL all metadata lives in files. That includes directories. So ANY change to a directory entry will cause the modification time on the directory to be updated. This will in turn change the mod time on all relevant parent directories up to the root. On a traditional filesystem like NTFS or UFS this would be a performance disaster as it would generate lots of additional seeks, so they don't do it. However in WAFL an change to a file will cause all relevant metadata inodes up to the root inode to be rewritten [in new locations without seeks] anyway, without a performance cost. Hope this helps.

This option caused me all sorts of trouble with intermittent network connection failures (I think due to a bug in Microsoft's implementation of this RFC) I would recommend turning it off if you are having any problems at all: ip.tcp.sack.enable off -----Original Message----- From: Stephane Bentebba [mailto:stephane.bentebba@fps.fr] Sent: 19 May 2003 15:14 To: alexis.osorio(a)intek.com.co Cc: NetApp List (E-mail) Subject: Re: Filer F840 Network Path? network path not found ... if you are in 6.3 or 6.4 , check for an option called : ip.tcp.sack.enable check it is on, so turn it off and redo the test , does it works ? sack was still experimental not a long time ago i think , sack from microsoft shouldn't discuss the same way filer's sack talk i think this option should be turn off for a while Helberth Alexis Osorio O. wrote: >I have a F840 on Windows NT Domain? > >Wheni try to mapping the path C$ or any other path of the filer, the system >cannot find the network path. > >In the administrative Tools, "Server Manager" i see the computer, type and >description, selecting the computer and properties i receive the next >message: > >"The network path was not found", please anybody can help me. > > >Thank you very much. > > > >Helberth Alexis Osorio O. >Professional Services Manager > > >Information Technologies de Colombia "INTEK" >Teléfono: (57-1)6206370 ext 15 >Fax: (57-1)6206365 >Celular: (57-315)3108457 >Santafé de Bogotá, D.C.

exportfs -u -a
by Robert Borowicz 21 May '03

21 May '03

Perhaps I'm rusty with my NFS knowledge.... I made a change to my /usr/local export. (-root on a build host) I did an "exportfs -u -a" and to my horror all of the *existing* /usr/local mounts went stale. I do not remember this happening with Auspex's (in a previous life) and SunOS 4.1.2. Perhaps I need to go back to the blue NFS/NIS O'Reilly book.... Is this a Solaris 2.8 ism, or am I missing something obvious in my re-entry to the world of NFS... Here is my vfstab entry: well:/vol/sysvol0/local - /usr/local nfs no yes bg,soft,intr TIA -Bob

I *KNOW* what the command does. I've read the man page and the book. HOWEVER, the way this used to work (and apparently not anymore) was you were free to unexport/unshare a dir/vol globally (IE: exportfs -u -a /usr/local) but it would *NOT* affect *EXISTING* mounts. Just newly requested ones. I'll go quietly now... -Bob At 11:16 AM 5/21/2003 -0500, you wrote: >man page says it all, dude! > >SunOS/BSD Compatibility Package Commands exportfs(1B) > >NAME > exportfs - translates exportfs options to share/unshare com- > mands > >SYNOPSIS > /usr/sbin/exportfs [ -aiuv ] [ -o options ] [ pathname ] > >DESCRIPTION > exportfs translates SunOS 4.x exportfs options to the > corresponding share/unshare options and invokes > share/unshare with the translated options. > > With no options or arguments, exportfs invokes share to > print out the list of all currently shared NFS filesystems. > > exportfs is the BSD/Compatibility Package command of > share(1M) and unshare(1M).

I know that. But in the past it would simply fail to make any *new* mounts, not undo existing mounts.... At 08:40 AM 5/21/2003 -0700, Jason.Santos(a)pinnaclewest.com wrote: >It did exactly what you asked it to do: unexported (-u) all exports >(-a). >

RE: useradmin command
by Ehrhart, Rick 20 May '03

There is currently no way to limit admin users. See burt 42514. However you can restrict rsh and telnet access with: options.rsh.access and options.telnet.access. For example: options.telnet.access "host=admin_host". This will only allow telnet from the computer admin_host. Please check the man page for more details. - Rick - > -----Original Message----- > From: Robert Borowicz [mailto:rbaus@swbell.net] > Sent: Tuesday, May 20, 2003 7:49 AM > To: toasters(a)mathworks.com > Subject: useradmin command > > > I'm using the "useradmin" command to add users to my DOT > 6.3.1 for CIFS > authen since I don't have a DC. > > Unfortunately these users also become Filer Administrators > and I have to be > very careful not to let them onto the box.

disk drive fails and netapp thinks there is an open in the FCAL l oop
by DFinn＠studentadvantage.com 20 May '03

This is the second time this has happened in the past week. I'm thinking there might actually be a hardware issue somewhere along the FCAL loop but does anyone else have any theories. from the message log: . . .

Turn them back on, boot the netapp up and it comes up fine, both times same scenario. The previous time a disk had it's red LED lit up so it was easy to tell that it needed replacing. This did not happen this time. I pulled disk 1.42 because I thought it might have been the one causing problems and it's been replaced with a spare. Should I also pull disk 1.1? Thanks Dan One other strang thing. I can no longer log into Filer View. It prompts me for the password to the netapp, then once I enter the password it comes back with the following error : "Error communicating with host na4m-be msg=Connection refused: connect". Is the password for Filer View the same as the root password for the netapp. I am still able to telnet in. I tried disabling and enabling the httpd server and that didn't seem to help.
