ORA-07353 on NetApp F760 at 100MBit
by Joseph Bishop 17 May '02

17 May '02

Hello folks, Has anyone seen a message like this while trying to create an Oracle datafile from SUN Solaris under heavy Network load? ERROR at line 1: ORA-01119: error in creating database file '/blah/blah/blah.dbf' ORA-07353: sfccf: close error, unable to close file. SVR4 Error: 11: Resource temporarily unavailable There isn't much noted on the Oracle site. I am just curious if anyone has seen it and if it is an NFS timeout problem? I have checked /var/adm/messages but I don't seen anything. Joe

Antivirus Scanning in DOT 6.1.3
by Allen, Pat 17 May '02

17 May '02

Hi everyone, I'm taking a look at the antivirus scanning capabilities in DOT 6.1.3. I've looked at the white paper that NetApp put together (http://www.netapp.com/tech_library/3107.html) and have some questions for those of you who might have implemented it: 1. What kind of performance impacts do you see in production environments? 2. What type of network interconnects are you using? In particular, would a VLAN on top of gigabit Ethernet be OK? 3. Are there any recommendations about the vendors? We use Trend ScanMail for our Exchange servers and have been happy with that product. We also use NAV for our desktops. 4. Are there any horror/satisfaction stories or questions I missed?

lock manager in 6.2 is broken....fyi
by Jeff Kennedy 17 May '02

17 May '02

There is now a bug id regarding the lock manager in 6.2. Using ReflectionX to nfs mount a volume under 6.2 causes failed writes/copies with a 'delayed write error' message. After a bit of testing with support they have concluded that it's definitely a bug in OT. Apparently the lock manager was completely rewritten for 6.2. The bug id is 71703. It may still be internal. -- ===================== Jeff Kennedy Unix Administrator AMCC jlkennedy(a)amcc.com

Fastlane DM Administrator

I was wondering if anyone uses this product against their filers? I have an 840 cluster running 6.1.2r2 and would like to have an operations group administer local cifs groups and directory permissions. We use this on our NT side and it works well but we've run into a few bumps with the filer. I don't want this group to have root permission but I don't want to be bothered updating permissions for every directory on the thing. Is there another product that is commonly used? Thanks Don

Re: Do file locks affect snapshots?
by Don.Hickey＠alcatel.com 17 May '02

Steve One thing to note is that if you are running in a multiprotocol environment you may find some snapshot files inaccessable through windows. The reason: If you access a file via NFS only and later try to view/recover that file from a snapshot directory with windows the result will be permission denied. This is because the first time you access a file with windows it converts the filename to unicode format. It can't do this inside a snapshot since it is a read only filesystem. There are cifs and wafl options you can set to avoid this. You noted that later you could access the file via w2k.... was it the same snapshot or a later snap? I suspect if you were doing a filer wide virus scan then the file would have been touched (in the live directory) thus converting it to unicode.... Just a thought.... Don Steve Losen <scl(a)sasha.acc.virginia.edu> Sent by: owner-toasters(a)mathworks.com 2002-05-09 09:59 AM To: toasters(a)mathworks.com cc: Subject: Do file locks affect snapshots? We are running ONTAP 6.1.1R2. I thought I read somewhere that there are no file locks in a snapshot. The snapshot is read only, but no files are locked, so you can open any file if you have the necessary permissions. However, I was running a virus scan (Norton) on a snapshot and it failed to open a few files, according to the log. I'm pretty sure it was not a permissions problem. We use unix passwd authentication for CIFS and therefore all files have unix permissions. The CIFS user was root (uid 0) and Norton successfully scanned about 180,000 files, many of which are readable only by owner (and superuser). Norton failed to open 16 files. Here is an error from the log: Scan could not open file F:\weekly.0\a\af\afc3f\private\Disparity.doc [00000012] (We made a read only share out of the .snapshot directory and attached it to drive F) So that got me wondering about file locks. If a file is locked when a snapshot is created, is the lock included in the snapshot? And if so, does it lock the file in the snapshot? Or else, if a file in the active filesystem is currently locked, does that affect access to the corresponding file in a snapshot? Later on, using the same share as above, I was able to copy the file to the local desktop, so W2000 was able to open it. Maybe it's a Norton thing. I'll try and look up that error code [00000012]. Is this a CIFS error perhaps? By the way, Norton failed to open some other files with error code [00000003] but the ones I checked were all symlinks that the filer could not follow, so that makes perfect sense.

CIFS Virus Scanning
by Strange, John 16 May '02

16 May '02

Hey Gang, I need to create a cifs share that I can virus scan monthly, I would like to set this up with CIFS, but the underlying unix permissions seem to override and I get permission denied on the files. Is there anyway I can setup a CIFS share that does not use the underlying unix permissions. I had the share set to full permissions and it does get some of the things but a few locked down unix directories seem to get permission denied on. Unless someone knows a good virus scanner that will run on linux/solaris. Thanks, - John

John, Our email group has just gone through research on anti-virus for Solaris. They suggest looking into Trend Micro VirusWall .

Oracle 8.1 vs. netapp
by Chris Moll 16 May '02

16 May '02

Anybody seen any performance changes with going to oracle 8.1.7 (from 8.0.5) with the databases on netapp storage? (host is sun enterprise 5000, solaris 2.6). Many batch jobs ran dramatically slower on a DB that was upgraded from 8.0 to 8.1. Fingers are getting pointed to the netapp, partly 'cause nobody wants to contemplate down-revving the database. The fact that the jobs ran fine on the netapp before the upgrade would seem to exonerate it but it's a convenient target... A few efforts at tuning the DB seemed to reclaim much of the loss; I'm no oracle expert but it sounds to me like the DB is far from optimal, for example it's set to a 2k block size which seems questionable to me. Anyway - anyone encountered anything similar? Chris Moll Lawrence Berkeley Laboratory

Diskshelf/FC failure modes
by Garrett Burke 15 May '02

15 May '02

Hi All, I'd like to get some feedback on what issues people have seen in the field with diskshelves and/or FC loop that have caused either decreased performance, an outage or cluster failover. In particular I'd like to know if any particular shelves seem more error prone to either failures or operator error e.g. disks not seated properly, misconfiguration etc and also how people have found the DS14 shelves in the field. I've both SCSI ( F230, F520) and FC filers (F720, F740, F740c, C760, F840 and F840c) with FC8, FC9 and DS14 shelves. Thanks, GB ---- Garrett Burke, Operations Manager, Eircomnet. http://www.eircom.net

NetIO DMA Re-ACLing
by Lim, Weng Kiam 15 May '02

15 May '02

Hi, Seeking feedback from users who had tried using the NetIQ's DMA (Domain Migration Administrator) to migrate from NT to 2000 domain and perform the re-ACL on all files in the Netapp filer. Any issues that I should watch out for? TIA Weng-Kiam Lim
