RE: usermap problem
by Åke Beckman 06 Mar '07

06 Mar '07

It IS possible, as Tom states, to do the usermapping through ldap, it's been around for quite some time.. Check options cifs.trace_dc_connection to see if the connection to the ldap server is working. (Don't know if this is valid only for AD ldap services...?) Maybe the password for ldap access got screwed up after the upgrade? options ldap.name user_name options ldap.passwd password I couldn't find any open bugs for ldap on 7.2.1.1 Regards / Åke ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Glenn Walker Sent: den 1 mars 2007 14:47 To: Langborg Tom; Parisi, Justin; toasters(a)mathworks.com Subject: RE: usermap problem For like usernames, it will work.

RE: vol copy speed and copying over root aggregate

Why not set up a volume snapmirror now for weekend work for migration? (i.e. vol_old to vol_new) We use this quite successfully - then when the migration is on you only have the update to do...

März 2007 10:53 An: toasters(a)mathworks.com Betreff: vol copy speed and copying over root aggregate Wichtigkeit: Hoch Hi, This is relatively urgent. We are facing the following problem. We need to move data on FAS270C (appr. 2TB) onto another set of disks. There is a single aggregate that contains root volume and one or two (on two heads respectively) large volumes with single LUN on each. All volumes except root are 100% full. DOT 7.0.3. Disks are 146GB 10K, RAID_DP, 14 disks on each head (average). Target set is 300GB 10K, RAID_DP, 11 disks on each head. I tested (under normal conditions) vol copy from root volume onto root volume copy. It tool 3 and half minutes for 440MB! It is absolutely unacceptable, we cannot afford this downtime. No the questions are - How are chances that without client load vol copy will be faster? What can explain that miserable performance for relatively small data set? - Which speed can be expected under these conditions? Normal on-tape (non NDMP) backup from client systems - Windows only, SAN attach - runs approximately 20MB/s which are still acceptable. - will aggr copy be faster and how much? If yes - how can I then switch root aggregate? To clarify - first I restrict target aggregate and make aggr copy. Then I put target aggregate online and get duplicate volumes, do not I? I _hope_ that filer will rename them, anyone can confirm? - any chance updating to 7.0.5 *before* copy will help? Thank you and I appreciate your answers.

Maximum number of groups per user
by Francois Joubert 02 Mar '07

02 Mar '07

Hi I am new to the list. I have been trying to get a definitive statement from NetApp about the maximum number of groups a user can belong to if we rely on the /etc/group and /etc/passwd files on the filer. The setup we have tested has CIFS clients (Windows2000) with the filer part of a workgroup. We rely on unix group permissions for access to data directories. We are not using any NFS, NIS, LDAP or NT domain - all local authentication etc. I have done some testing and it appears the limit is 32 (not a surprising number) but have not been able to get this confirmed. Has anyone tried/done this before? We are migrating from samba servers running on FreeBSD with modified kernels which allow users to be in thousands of groups (don't laugh; I don't want to go into the reasons) because this facilitates our companies working practices. Thanks Francois

SANOWN not enabled
by Steven Mandrake 01 Mar '07

01 Mar '07

Hello, I recently replaced a brocade switch in my fabric. trying to see if my NTAP is connected to the switch. If I type normal commands like storage show fabric and switch -- I do not get a returned value. But one thing confuses me --- when I type 'storage show initiators' --- I get 'SANOWN not enabled' What does this mean? Now site doesn't have any information. Does this need to be enabled for NTAP to work on FC-SAN?

FW: autosupport stops functioning
by Bender, Marilee 28 Feb '07

28 Feb '07

We had this issue too. I agree with the post below that it could be message size. However, if it's just past asups that were too large because of the messages file (or one of the other attachments), you can set the autosupport.content size to minimal to delete all the queued asups, then "doit" to generate one without the attachments to see if you receive it, then put the content back to complete. It cleared the issue on one of our NearStores....the other one appears to have a "corrupt" character in the data chunk as viewed from the smtp server logs. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Sphar, Mike Sent: Tuesday, February 27, 2007 2:19 PM To: toasters(a)mathworks.com Subject: RE: autosupport stops functioning I don't think this is the same problem as the one originally posted, but we once had a similar problem here where autosupport messages stopped being received by netapp because our mail gateway was rejecting all messages larger than a certain size.

It gets sent to netapp as part of the autosupport. I got an automatic email from Netapp support telling me that they hadn't received an autosupport for two weeks. Buried in my huge /etc/messages file was an error indicating that autosupport had failed, but no reason why. This particular filer holds our home directories and gets a lot of CIFS logins, which we want to log. We have enabled CIFS login tracing, which is very verbose. I used /etc/syslog.conf to divert the CIFS auth messages to another file: *.warning;auth.none /dev/console *.info;auth.none /etc/messages auth.info /etc/cifs_auth_log I rotate the cifs_auth_log with a cron job because I think ONTAP will only rotate /etc/messages. Now /etc/messages only grows to about 200K and autosupport is working again. Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support
