Re: CIFS/NFS file sharing in a non NIS environment
by Thorsten.Lemke＠computacenter.com 21 Oct '03

21 Oct '03

Hi, I have no solution for you, but as a first step in troubleshooting the cifs access, I would recommend to activate the option cifs.trace_login on the filer. Subsequently monitoring the messages on the filer console while the user tries to login usually gives you a hint why the request is denied. You can also use the "wcc" command on the filer to check the user mapping.

I want to share UNIX style qtrees on PC and UNIX. Currently, if a qtree has UNIX style permissions it will not allow the PC user to open a share. If the qtree has NTFS permissions it will not allow UNIX users to access the share. I have a set-up in my own office where we have NIS, and this handles the name resolution. However, the office I am in currently does not have NIS. I have tried createing a password and group file on the filer, identical to the password files used on the UNIX systems, however this has no effect. Any ideas?

F740/760 Power Supply Question
by Chris Abernethy 20 Oct '03

20 Oct '03

Our hosting provider has different rates for power depending on how backup power supplies are used, can anyone shed some light on how Netapp power supplies work? Do the dual power-supplies on F740 and F760 filers both draw power when plugged in, or does one draw power and the other remain inactive until a failure occurs? --Chris -- ========================================================= Chris Abernethy | Voice: 617.912.2016 Senior Systems Administrator | Fax : 617.880.7783 Student Advantage, Inc. | chris(a)studentadvantage.com

RE: Manually failing disks
by bryan_bahnmiller＠agilent.com 20 Oct '03

20 Oct '03

Rob, I remember testing the process of failing disks on our test filer - an F87. When we did this, the filer wrote something somewhere (I can't remember offhand) and we had to trade in the disk. We called NetApp when we tried to re-use the disk and the system would not accept it. NetApp told us the only way for us to continue was to actually replace the disk.

PLEASE READ AND REPLY!!!

Dear Brethens, As you read this, I don't want you to feel sorry for me, because, I believe everyone will die someday. My name is ZULU DANIEL, a merchant in Dubai, in the U.A.E.I have been diagnosed with Esophageal cancer which was discovered very late, due to my laxity in carrying for my health. It has defiled all forms of medicine, and right now I have only about a few months to live, according to medical experts. I have not particularly lived my life so well, as I never really cared for anyone not even myself but my business. Though I am very rich, I was never generous, I was always hostile to people and only focus on my business as that was the only thing I cared for. But now I regret all this as I now know that there is more to life than just wanting to have or make all the money in the world. I believe when God gives me a second chance to come to this world I would live my life a different way from how I have lived it. Now that God ! has called me, I have willed and given most of my properties and assets to my immediate and extended family members and as well as a few close friends. I want God to be merciful to me and accept my soul and so, I have decided to give alms to charity organizations, as I want this to be one of the last good deeds I do on earth. So far, I have distributed money to some charity organizations in the U.A.E, Algeria and Malaysia. Now that my health has deteriorated so badly, I cannot do this my self any more. I once asked members of my family to close one of my accounts and distribute the money which I have there to charity organization in Bulgaria and Pakistan, they refused and kept the money to themselves. Hence, I do not trust them anymore, as they seem not to be contended with what I have left for them. The last of my money which no one knows of is the huge cash deposit of twenty four million dollars that I have with a Bank in Amsterdam. I will want you to help me col lect this deposit and dispatched it to charity organizations.email me I have set aside 10% for you for your time and patience. God be with you.

excluding a directory from dump
by William W. Arnold 17 Oct '03

17 Oct '03

Is there a way to exclude a directory (full qtree in this case) from a dump? I've experimented with the -X option, but that appears to only match the filename, not the full path to the file. -- -billy- warnold(a)vipnet.org

F740 Poor Network Performance.
by devnull＠adc.idt.com 16 Oct '03

16 Oct '03

Dear All, I have a F740 running Ontap 6.1.1R2 with 1 Gigabit and 2 100Mbps ethernet ports. I am seeing very poor performance on these hosts from Sun and Linux clients, running Solaris 8 and Rh 7.3(2.4.20-ac2) I am trying to dd a 200M file and i would like to check if the bottleneck caused is because of poor disk or network performance. Is there an easy way to check disk performance while i dd the file to a particular volume(the netapp has 3 volumes and all 3 have equally bad results) I dont think that the Solaris and Linux clients are configured wrong, i have an F810 that for now seems to be performing pretty close to my expectations. nfs has tcp enabled on both filers. Anything unsual to look out for doing a snoop etc. Can anyone also confirm whether default mount on Solaris clients is tcp or udp ? I seem to want to think that it is udp if not specified either in the NIS maps or mount options. Thanks, -- /dev/null devnull(a)adc.idt.com

RE: Deleting qtree
by Alan McLachlan 15 Oct '03

15 Oct '03

Thorsten, Be careful with the way you word things. Saying "the data will move to the snapshot area" implies that data is actively copied out like in other vendors snapshot implementations (Compaq/HP Virtual Replicator, EMC SnapView, etc) which would generate a negative performance impact and the potential for snapshot failure, which are two issues that are suffered by the other vendor products. The ability to do "passive" snapshots as a side-effect of the no-update-in-place policy of WAFL is a major differentiator for Network Appliance. Rather, say "the data is no longer marked as part of the active filesystem". It's still protected by the snapshot block map of course, until all the relevant snapshots are deleted.

The blocks in your qtrees are already marked as belonging to serveral snapshots if the data already exists for some time (what I assume). Once this has happened you can't do anything about it. If you delete your qtrees, the data will move to the snapshot area. The remaining qtrees are not affected. You are not able to differentiate between snapshots of different qtrees as a snapshot is always taken of a whole volume.

RE: Disk numbering order in SDS12 ?

The disks in the DC-12 shelf are located like this(front left to right). 15 14 13 12 11 10 09 08 03 02 01 00 If the disk is already failed, you don't need to do it again. Check the message section of your autosupport-mail to find out which disk is failed. Remember to run "disk swap" before changing disks.
