Russ, You'll need to send an email to "majordomo(a)mathworks.com" and put the words "subscribe toasters" in the text. The process is similar if you want to join the "emcnas" list.

RE: Anitvirus on netapp
by Jonathan Dodman 31 Jan '01

31 Jan '01

We have two F760's which have an NT4 janitor box, running Netshield 4.5. We have set Netshield up to carry out scheduled scans of the volumes on a daily basis (set up admin shares on the filers for each volume). We have also throttled the scans to low priority, so that they do not interfere with the performance of the filers. This works fine, but only if a small ammount of data is on the filers (We have about 300GB), as this provides enough time for the scans to complete within a 24 hour period. On access scanning is the main bugbear, as our users work on Citrix Metaframe on Windows 2000 Terminal servers, which does not support on access virus scanning !! Does anybody else know of a way around this ?

We use Trend Micro's OfficeScan from a Windows 2000 Pro desktop. I've written a batch file and scheduled it to run every night. I would feel more comfortable with a real-time scanning solution, so I am working with Trend to get my hands on a beta of the product that they have designed for NetApp filers. Here is the batch file if anyone is interested. net use w: \\%servername%\d$ <file://\\%servername%\d$> c:\progra~1\office~1\pcscan.exe w: /a /nm /c /zc /r=w:\ net use w: /delete Best Regards, Josh Gifford Windows NT/2000 System Engineer Siemens Power Transmission & Distribution 7000 Siemens Rd Wendell, NC 27591 Phone: (919) 365-2806; Fax: (919) 365-1080 Email: josh.gifford(a)ptd.siemens.com -----Original Message----- From: Goebel, Uwe [mailto:uwe_goebel@mentorg.com] Sent: Tuesday, January 30, 2001 2:53 AM To: toasters(a)mathworks.com Subject: Anitvirus on netapp Hi there, I'm curious how everybody is checking against viruses at the filers.

Backup Solution
by Mike Horn 31 Jan '01

31 Jan '01

I have a f740 filer currently being backed up with one DLT7000 tape drive. I'm tired of switching tapes. Does anyone have any experience with either "Sync Sort or Workstation Solutions" as the software to backup a filer? I am looking to use Spectra Logic products on the hardware side. Any input would be greatly appreciated. Thanks Michael A. Horn Associate Geophysicist Chesapeake Energy Corporation 6106 N. Western Avenue P.O.

RE: Virus scans on NetApps and backups
by Coder, James (STP) 31 Jan '01

31 Jan '01

We had this problem until recently - NetApp was helpful in supplying a solution. The virus software we use cased the ctime to be changed and when using NDMP the it took it as a changed file. Run the following command on your filer and see if this helps. It did us. ndmpd ignore_ctime This was for our 760 NT filer with the NetBackup backup app. Prior to this, we were backing up every file the scan touched at night (about 20% of 1.2 TB). The only place we could find a reference to the command was in a white paper. James C.

Strange behavior between f630 ontap5.3.6 & Solaris 7
by svawter＠c-cube.com 30 Jan '01

30 Jan '01

I must be missing something but let me bounce this off the croud... I have an f630 with ontap5.3.6 sharing out NFS data to a Solaris 7 box and in certain directories I get this error: /bin/ls -F (or -l also causes this) ls: "suid_mounts_allowed.dat": Value too large for defined data type A truss showed this: lstat64("suid_mounts_allowed.dat", 0xFFBEF958) = 0 acl("suid_mounts_allowed.dat", GETACLCNT, 0, 0x00000000) = 4 brk(0x00025E58) = 0 brk(0x00027E58) = 0 lstat64("suid_mounts_allowed.dat.old", 0xFFBEF958) Err#79 EOVERFLOW getfacl suid_mounts_allowed.dat.old doesn't show anything different than any other file in the directory... These errors don't show up on Solaris 5.5.1 or Solaris 5.6, but is consistant on different Sol7 systems. My other thought was inodes, but there are files that don't get an error with higher inodes. Anybody have an idea? Steve Vawter voice: 408-490-5310 fax: 408-490-8615 Staff UNIX Systems Administrator Steve.Vawter(a)C-Cube.COM

2 q's - quotas and tape drives
by neil lehrer 30 Jan '01

30 Jan '01

hi, q1. how much of a performance hit does keeping quotas have? i'm thinking of hard quotas for users on their home dir thru home qtree, and, quotas for groups on the shared qtree. any other issues on quotas? our groups and users are kept in NIS. q2. i am considering using a spectralogic treefrog tape unit for local ndmp backup. 2 ait2 drives, 30 slot library. any comments on the treefrog or spectralogic?? -- thanks

RE: 2 q's - quotas and tape drives
by Maglinger, Paul 30 Jan '01

Along the same lines, we're working on creating home directories for users here at the corporate office. We're wanting to limit the amount of storage per user, but from what I've read there is a limitation of 254 qtrees per volume. We're running NT, so therefore using CIFS, and using Ontap 5.3.7R2. We are also running NetIQ, but can't install the agent on the filer. We could limit the disks per volume, but smaller volumes waste more disk space. To give you an idea, we're considering limits of either 250 or 500MB per user. -----Original Message----- From: neil lehrer [mailto:nlehrer@ibb.gov] Sent: Tuesday, January 30, 2001 12:48 To: toasters Subject: 2 q's - quotas and tape drives hi, q1. how much of a performance hit does keeping quotas have? i'm thinking of hard quotas for users on their home dir thru home qtree, and, quotas for groups on the shared qtree. any other issues on quotas? our groups and users are kept in NIS. q2. i am considering using a spectralogic treefrog tape unit for local ndmp backup. 2 ait2 drives, 30 slot library. any comments on the treefrog or spectralogic?? -- thanks

RE: Backup Solution
by Loux, Linda 30 Jan '01

I have been using SpectraLogic 10000 (Bullfrog) with Veritas NetBackup for backups for several months. I've had very little problems with them. Configuring the Media servers and filers take a bit of time, but once that is established, there have been few problems. Occasionally I have had to reboot the filer and associated SpectraLogic, but have not been able to nail the problem down to which one is causing the problem.
