setting up user quota
by Abu Ihsan 10 Aug '00

10 Aug '00

Hi, whenever I use user name instead of UID I will get below error : toaster>quota on web quota: user name ihsan not found (/etc/quota line 2). could not read quotas file toaster> content of /vol/vol0/etc/quotas ihsan user@/vol/web 5M * user@/vol/web 3M It won't fail if I use UID Any suggestion ? I tried putting clients /etc/passwd in /vol/vol0/etc/passwd and it works. Do we have to have a /vol/vol0/etc/passwd ? If so, how about if we have let say 100000 users ? there has to be a smarter way which a newbie like me do not know of... thanks, --abu ihsan __________________________________________________ Do You Yahoo!?

RE: NetApp questions

No account/password is required for *NIX access to the filer via NFS; that's all handled via the standard NFS permissions and *NIX filesystem permissions. As to running Oracle with the data and logfiles on a filer via NFS, I should think that even with a NetApp using Gigabit Ethernet, you'd take a -huge- performance hit as compared to a local disk array. I've no empirical data to back this up, mind you; it's just that there's so much overhead associated with NFS even on an optimized platform like the NetApp filer, I can't see it as being a win. If there's anyone out there with Oracle experience on filers via NFS, either pro or con, I'd love to hear from you. ----------------------------------------------------------- Roland Dobbins <rdobbins(a)netmore.net> // 818.535.5024 voice -----Original Message----- From: Jiang, Perry [mailto:Perry.Jiang@BMO.com] Sent: Tuesday, August 08, 2000 2:18 PM To: toasters Subject: NetApp questions Hi, there I have a question regarding NetApp Filer 740. Oracle account I am running a Solaris Oracle server, which is a NFS client of the NetApp Filer. Do I have to create an Oracle account on NetApp Filer and put the entry in /vol/vol0/etc/passwd? If yes, what the purpose of that? An on-line NetApp document, "Oracle for UNIX: Integrating with a NetApp Filer", stated that you need to create an Oracle account on Filer. However, according to the System Admin. Guide, /vol/vol0/etc/passwd is only for CIFS, not for NFS. You explaination is appreciated. Perr Jiang

Snapshots and Oracle
by Aaron Sherman 10 Aug '00

10 Aug '00

I have a few snapshot questions for anyone else who's running Oracle: 1. Does a hot backup (as described on http://www.netapp.com/tech_library/3049.html) present any restoration problems? Has anyone done a restore from a hot backup? 2. Hot backups are as close to "live" as you're supposed to come, but it seems to me that a nice extra bit of paranoia would be to take snapshots 2-3 times per day of the live database. The image would be consistent, and Oracle would come up off of it as it would from a crash (unlike, say a tar of the data-files which would be junk). The only problem would be that you would loose any half-completed actions which were not correctly tansactionalized. Can anyone comment on this? 3. Has anyone seen roughly how much storage an Oracle snapshot takes? It seems to me that it would be larger than a filesystem snapshot because more blocks are changing. Of course, it depends on your read/write ratio, but is there a general consensus? I've so far been very impressed with my filer. Oracle over NFS sounded outright dumb to me at first, but damn if it isn't faster than local disk.

SV: Replacing defective DLT7000 drives without rebooting the fil er
by Karl Erik Øyøygard 09 Aug '00

09 Aug '00

Klaus, I change drives on the fly all the time. ESD is a big issue here, so get out your antistatic wrist-strap and make sure the host and library share the same power connection/ground! Make sure the new drive is the same type, SCSI-ID and if possible same FirmWare. The host will see the new drive, just make sure it is not down/offline when you are finished. This is not the recommended way, but often you just can't wait several weeks for the next sheduled downtime. This goes for most systems, not just filers. -OYOY- Med hilsen - Best Regards, Karl Erik Øyøygard ProAct Systems AS Postboks 3047 - Lade Haakon VII's gt. 7 7002 Trondheim Tlf: 73 92 21 44 Fax: 73 92 08 88 Mob:93 25 24 24 E-mail: karl(a)proact.no SMS: +4793252424(a)sms.netcom.no --------------------------------------------- For every complex problem there is an answer that is clear, simple, and wrong. -- H L Mencken

Fwd: RE: Moving from one NT domain to another.
by Joan Pearson 09 Aug '00

09 Aug '00

Burt 14378 addresses this problem. It is fixed in a future release. When changing the filer's domain, if the builtin/administrators group contains the old domain's administrators group, it is removed and the new domain's administrators group is added.

RE: Moving from one NT domain to another.

Jeremy, You are right, the administrator (DomainAdmins) of the OLD domain will still be member of the local administrators on the filer after the move, because Lclgroups.cfg is not updated. This is how I do this: Rename cifssec.cfg, filersid.cfg and lclgroups.cfg in /etc on the filer. Add filer via servermanager to the new domain. Run `cifs setup` Edit /etc/cifsconfig.cfg and remove all referances to users/groups in the old domain. They will not show up correctly in FilerView! And you may have to correct the ACL's on a LOT of files... Remember to set new users as owner of home directory's for cifs homedir to work... I'm not sure you need to get cifssec and filersid out of the way, but it will work if you do. Good luck! -OYOY- Med hilsen - Best Regards, Karl Erik Øyøygard ProAct Systems AS Postboks 3047 - Lade Haakon VII's gt. 7 7002 Trondheim Tlf: 73 92 21 44 Fax: 73 92 08 88 Mob:93 25 24 24 E-mail: karl(a)proact.no SMS: +4793252424(a)sms.netcom.no --------------------------------------------- For every complex problem there is an answer that is clear, simple, and wrong. -- H L Mencken > We have an interesting problem that I'm hoping somebody on the list has > first-hand experience with.

RE: Filer storage for databases, seriously? (Was: Re: NetApp ques tions)
by Eyal Traitel 09 Aug '00

Nicholas, 1. It depends how you define performance. Restoring a database in a very short time is also great performance, and you will not get that in DAS, no unless you pay for 1 more copy of the data. 2. You should always look not at performance alone, but on price/performance, which today is with all these TCO-based calculations. This brings to the point where a fully loaded F760 with Gigabit card, can perform better than you can think of compared with those DAS systems, which forces you to the old world of static unshared copies of volumes... I believe that the fact that more and more eCommerce sites are choosing NAS (and mainly from its market leader...) as the solution will prove you better than any benchmark that this is totally possible and usable solution. Eyal. (I ran a small Orcale database of ~5gb, no problems, have no idea on bigger configs... sorry!) ===== Yours, Eyal Traitel eTraitel(a)yahoo.com, Home: 972-3-5290415 (Tel Aviv) *** eTraitel - it's the new eBuzzword ! *** __________________________________________________ Do You Yahoo!?

Whoops, my screw up. I said raid 0 when I ment raid 1. This would make it 6 disks, not 3. But still the point is valid. 6 disks versus 14 is a large amount of disks.
