program to warn for over quotas
by glennm＠latticesemi.com 22 Oct '01

22 Oct '01

I have started using SWatch to monitor quotas on my F740. SWatch, The Simple WATCHer, can be found at: http://www.oit.ucsb.edu/~eta/swatch/ It is great for monitoring all kinds of system files. I use it to let me know when one of my users has hit their quota. This allows me to act on it promptly. Here is my .swatchrc file for my filer named "toaster" that is mounted on my admin system where the progam runs: ---------------------------------------------------- # # Swatch configuration file for constant monitoring # # people out of quota on praxis watchfor /disk quota exceeded/ echo mail ---------------------------------------------------- I enter the command "swatch --tail-file=/toaster/etc/messages" and it both echos the error in the window and emails me the error. Of course the user is a UID as NetApp has not setup the error so that it translates the uid to a user. I am working on the program, it is in perl, to do more for me. I have perl version perl5.005_03 and I had to get several modules to get it to make, but it wasn't to bad. The cool thing is I want to update to 6.1.1R1 so that the quota threshold can be used. Then I can have a program warn the user when they are getting close to their quota limit. It would be nice if this was built into the NetApp though. ************************************************************************* Glenn Marsh Lattice Semiconductor Corporation Unix Systems Administrator 5555 NE Moore Court CAD Engineering Hillsboro, Oregon 97124 glenn.marsh(a)latticesemi.com 503-268-8000 503-268-8136 phone - 503-268-8459 fax *************************************************************************

RE: Veritas Netbackup Database

Manny, I could not try the disaster recovery. I did move the /usr/openv/netbackup/db to the NFS mounted file system. I am not backing this up with NDMP. I just use regular "catalog backups" to the tape. When you configure regular Solaris Backup class in NetBAckup, there is an option "Follow NFS". There is no option like that for catalog backups. I wonder if the catalog backups truly work. VEritas could not answer this question, their advice was to recover. I can not afford to fail and recover the DB right now, it is something on my list.

RE: DLT 7000 question

Hallo Rahul, the problem is that the 40/80GB label on the tape package is purely marketing based on the DLT8000 drive. What counts is the type of drive and the compressability of the data. In your case the DLT IV tape is marketed as 35/70GB. Without compression 35 and with 2:1 compression 70 GB. But the compression depends on the data, which means you can have more or less. My experience with the data I back up is about 55 GB compressed, but I have already written 120 GB to one tape. For more information you should read (or download) the DLT Hanbook from www.dlttape.com, this book explains almost everything you would like to know about the current DLT tape drives and cartridges.

RE: Netapp hardware

You can add 36s and 18s in the same volume. If you add them to the same RAID group, the *first* 36GB disk becomes the parity(needed for the extra stripes) and the 18GB parity becomes a data drive(they flip roles). However, it is in my opinion, better to just simply make a new RAID group with the 36GB disks. They will be taken fully advantage of (i.e. they will be 36GB disks). However, if your current volume is a Zoned Checksum volume, and you add the new 36GB(34F) disks, you will lose the benefits of the BCS disks and they will work like Zoned checksum disks. Chances are your current 18GB disks do not have the little yellow labels and are ZCS. So you may want to create a new volume with the 36GB disks unless they are BCS disks already. This is perfectly legal, it has been being done for a long time now. (mixing drives of varying sizes). The one thing to remember, the largest disk in the RAID group is *always* the parity disk, unless of course they are all the same size in the RAID group. --tmac Timothy A.
