inodes vs. snapshots
by DANIEL CHANEY 21 Dec '00

21 Dec '00

Hi, long time reader, first time poster, love your list, etc etc etc. Do max inode counts follow snapshots? That is, if I do a snapshot on Monday, increase the inode counts on Tuesday, wipe my files on Wednesday and bring things back from the snapshot on Thursday, do I still need to increase the inode count as I did on Tuesday? -dan

RE: Problem on 840 Cluster..
by Fox, Adam 20 Dec '00

You'll need to floppy boot to the 1-5 menu (either using actual floppies or the PROM trick). Enter 5 to go into Maint. mode. Then from maint. mode you can rc_toggle_basic and use the vol rewrite_fsid command. toaster*> vol rewrite_fsid <vol_name> You only need to do this on 1 of the filers, but the cluster will have to be disabled while you do it. You can re-enable cf once both filers are up in normal mode. As stated before, feel free to call NetApp Support and have them walk you through the process. Hope this helps. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Bravo13S(a)netscape.net [mailto:Bravo13S@netscape.net] > Sent: Tuesday, December 19, 2000 10:25 PM > To: PrJain(a)shastanets.com > Cc: toasters(a)mathworks.com > Subject: Re: Problem on 840 Cluster.. > > > According to the /etc/messages.. your root volume has the same > FSID as another volume.

RE: 2 questions for f760
by Sam Schorr 20 Dec '00

20 Dec '00

Is this really, possibly, wonderfully true??!! Which version of ONTAP fixed this? The reason I ask is that on all our filers (mostly F760 and some F840's), the total number of folders at any one directory level was a function of the inode limit of a 2 bit, unsigned pointer - thus limited it to just under 65k directories at any one level. Since we have 9.5 million user directories spread across those filers, we had to write scripts to check when that threshold was being reached to create a new one. We would just LOVE to hear that this limit has been removed! -----Original Message----- From: Bruce Sterling Woodcock [mailto:sirbruce@ix.netcom.com] Sent: Tuesday, December 19, 2000 10:41 AM To: neil lehrer; toasters Subject: Re: 2 questions for f760 ----- Original Message ----- From: "neil lehrer" <nlehrer(a)ibb.gov> To: "toasters" <toasters(a)mathworks.com> Sent: Tuesday, December 19, 2000 9:25 AM Subject: 2 questions for f760 > hi, > > 1. we will be moving our home and share dirs from old sun boxes to > f760. the home dirs on the suns were set up like: > > \home > \home\a > \home\a\abe > \home\a\allen > \home\b > > etc. in other words, user homedirs under the first letter of the id. i > was told this was done for performance reasons, inode searching, on the > sun boxes. > > do i need to use this structure on the 760? is there a similar issue on > filers? or can it just be \home\userid? Unless you're talking 100,000 entries or so, it can be \home\userid. NTAP implemented a large directory performance enhancement a long time ago that could handle 10s of thousands of entries, and the 760 is many, many times faster than that. If you want to read the old paper, though: http://www.netapp.com/tech_library/3006.html Given the filesystem enhancements since then they may even have gone to b-trees by now. Bruce

RE: Problem on 840 Cluster..
by Watanabe, Steve 20 Dec '00

Premanshu, I assume you meant 5.3.6H1R2, not that it really matters. As for the failed takeovers it should fail in both directions as you have a volume on each node with the same fsid. The fsid is set when the volume is created and is based on the system id of the filer which is extracted from the nvram card. The likely way that this occurred was that vol0 was created on one node and then moved to the other node. Then another vol0 was then created on the first node. Note that when I say "moved" it could have happened if someone was playing with the cabling and switched shelves around. As for getting out of this, the easiest way is to redo the filesystems assuming you haven't populated the volumes with data yet. Otherwise I'd call netapp support and they should walk you through rewriting the fsids on one of the volumes; the one that doesn't match the system id of the host node. -Steve > -----Original Message----- > From: Premanshu Jain [mailto:PrJain@shastanets.com] > Sent: Tuesday, December 19, 2000 5:34 PM > To: toasters > Subject: Problem on 840 Cluster.. > > > Feel toasters will be faster to help... > Here is the description of my problem> > > > I have an 840 cluster running 5.3.5H1 R2.

SQL Server problem
by Tom "Mad Dog" Yergeau 19 Dec '00

One of our DBAs recently posed this question to Microsoft and the only response we got was some badmouthing of NetApp. If anyone has any insight and could help, please let me know. We don't know for certain if it's related to being network attached, or if the database is corrupt, or something else. Thanks, MD > Here is the problem: > We are using a NetApp to store large ~26 GB data warehouse database files > and recently one database went suspect. > One of the dba's that work for me tried to detach and reattach the database. > > This is the error that they received > > Server: Msg 3624, Level 20, State 1, Line 1 > > Location: pageref.cpp:4278 > Expression: rowLog.RowCount () == 1 || pPage->IsEmpty () > SPID: 53 > Process ID: 1528 > > Connection Broken > > There is nothing on MSDN or Technet about this > Do you have any suggestions?

NetApp and Oracle
by Schiel, John 19 Dec '00

19 Dec '00

I'd like to pose this question here and see where it leads. If this is not the appropriate forum, please let me know what is. I'm in a group where we need to implement a data warehouse. Our design so far is to purchase two 840 filers each with one terabyte of storage using the 36gb drives. On top of that we are going to use either a 420R or Netra 1405 sun server as the database server (solaris 8, Oracle 8.1.6). What we need to do is grab files off of a 760 filer that is in CDR (comma delimited record) format and load that data into an instance of Oracle. Our goal then is to use some method of getting the data off of the 'load' server to another server that will be essentially 'read only' for reporting purposes. These so far are separate servers and I'd like to stay away from Oracle Parallel Server (OPS) at this point because of the extra maintenance and design work that would need to be done to handle this. What I would like to know is what methods of data movement some of you have used. In our quote for the filers we have asked for SnapMirror but I have some reservations on how that might work with Oracle because of the SCN's that are in each separate instance of Oracle. John

First, Use Oracle SQLloader to load that data into the Oracle database. Second, Update the read-only-reporting Oracle database from the other database at desired interval. There are several methods to accomplish the second task. Method one: Run Oracle database in archive mode, after the first time load "that data" into the Oracle database, take a cold backup of the DB; use the cold backup to restore on the second server system (sun+F840) to create the reporting database. Then, use Snapmirror to ship archive logs to the reporting database system. Apply archive logs to update the reporting database at desired interval that can be done in scripts via cron job. This method is straight forward. Method two: Use Oracle Standby Database (replication) that provide you the ability to ship archive logs via net8, apply archive logs at desired interval to update/sync with the other database; and the standby database can be in read-only mode as reporting database. You will need to follow Oracle Standby Database documentation for configuration and operation of Oracle Standby Database. Please do not hesitate to contact me if I can provide any assistance.

RE: need help with Legato and Filer backup
by Benn, Paul 19 Dec '00

19 Dec '00

If you have files with NT-style permissions, though, backing up over NFS is not a desirable option as you will loose any NTFS file attributes including ACLs and DOS attributes. Backing up over CIFS not only retains NTFS file permissions but it retains UNIX permissions as well as tracks an archive bit on UNIX files (so NT apps can do "incremental" backups). If you have a lot of data, you should really consider an NDMP based solution. You can read more on NT based backup here: http://www.netapp.com/tech_library/3052.html Regards, Paul Benn Network Appliance -----Original Message----- From: Michael Salmon [mailto:michael.salmon@uab.ericsson.se] Sent: Tuesday, December 19, 2000 3:13 AM To: Dell, Mary; toasters(a)mathworks.com Subject: Re: need help with Legato and Filer backup +-- On Friday, December 15, 2000 11:28:24 -0600 "Dell, Mary" <mdell(a)mesirow.com> wrote: | | Is anyone out there using legato to back up your filer?
