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

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

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.

RE: Anitvirus on netapp

We're using our filer for data storage, so anything that goes on it has to come from workstation or server. We use Network Appliance, kinda taking a "perimeter" approach to the subject. Anything that goes on or comes off the filer has to go through a workstation or server. -----Original Message----- From: Marianne Lindberg [mailto:Marianne.Lindberg@nsc.com] Sent: Tuesday, January 30, 2001 09:28 To: toasters(a)mathworks.com Subject: Re: Anitvirus on netapp I'd be curious about what everyone (who has CIFS data on their Filers) is using as well.

RE: Virus scans on NetApps and backups

You could set Norton to scan only on file access, thus minimizing your changes. -----Original Message----- From: Paul Letta [mailto:letta@jlab.org] Sent: Tuesday, January 30, 2001 2:59 PM To: toasters(a)mathworks.com Subject: Virus scans on NetApps and backups We are using Norton AV Enterprise 7.01 to scan our filer via CIFS. We have found that as Norton scans each file, the inode change time (i.e. ls -lc) gets set to the current time. I think it is due to Norton messing with the DOS archive bit, but I am not sure. The problem is that this turns our level 1 ndmp dumps into virtual level 0 dumps. It seems that ndmp uses the inode change time, not the file modification time, as a basis for picking which files to dump during level 1's. Any suggestions ? -- Paul Letta Thomas Jefferson National Accelerator Facility Computer Center Unix System Administrator EMail: letta(a)jlab.org Phone: (757)269-5106
