Re: Qtree Utilization Alerts
by Steven Boyer 13 Jun '01

13 Jun '01

Dale I wrote a script, on a Unix client, that looks at each tree in the /etc/quotas file. If the tree is within 90% of the three it then sends an email the user who is responsible for the tree, our helpdesk, and senior admins. The file that I email also includes the sub directories of that tree so the user can get an idea of were he might be able to cleanup data. My scripts run once an hour mon-fri. ---------- Original Message ---------------------------------- From: "Dale Wolf" <wolfd(a)agcs.com> Date: Tue, 12 Jun 2001 16:29:20 -0700 >I am looking for a tool to send alerts in the form of email or NT alerts >when a Qtree reaches some threshold or percentage (say 80%) of it's >quota.

RE: Sudden CIFS performance degradation
by Traitel, Eyal 13 Jun '01

Diana, Since this might be of many many reasons, some on filer side, some on client side, I suggest you to open a case.

It ran fine since we upgraded to 5.3.6 around 10 months ago, until early this week, when we began experiencing severely degraded CIFS performance. In some cases, CIFS times out and the client experiences data loss. What should I be looking for? We had a similar problem with our other filer a few months ago, but never determined the cause; we ended up solving the problem by upgrading to OnTap 6. This time, I would like to determine the cause _before_ we upgrade, but time is of the essence. Help/tips appreciated. Thanks, Dianna

The command 'exportfs' on the filer itself, will also display the currently exported volumes. -----Original Message----- From: Lance A.

showmount?

Greetings, Is there any equivelant to the unix showmount command in OnTAP 5.3.X? I can't seem to find anything. --[Lance]

> > Is there any equivelant to the unix showmount command in OnTAP 5.3.X? > I can't seem to find anything. > Not that I'm aware of, but you can look in /etc/rmtab on the filer for that same info. Or you can run showmount from a client and give the server name, such as UNIX# showmount -a filer BUT PLEASE NOTE THIS CAVEAT: There is no reliable way to tell who all your clients are at any given time. NFS is stateless. Clients can come and go and they don't always leave nicely and do a clean umount so the entries tend to stay in /etc/rmtab for much longer than they should. If you want to see who the top 5 or so clients are, you can always use the option nfs.per_client_stats and then nfsstat -l and you'll get an idea of who your busiest clients are and presumably they are still mounted. The only showmount option that I have found to be truly reliable is the -e options which shows you what is exported from a particular box. Hope this helps. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com

DOT 5.x -> 6.x RAID/WAFL upgrade ?'s
by Jeffrey Krueger 12 Jun '01

12 Jun '01

Okay, can someone help explain to me what happens to volumes between Data ONTAP 5.x and 6.x with respect to the upgrade steps and times. In our situation, we're vol copy'ing data from 5.3.7R3 to 6.1R1. The first annoyance is that the destination filer (6.1R1) says the following: Mon Jun 11 15:57:13 PDT [turbine: rshd_0:error]: Filesystem version mismatch for destination volume vol2_2, reverting the version and aborting transfer. A console message will be displayed when this revert is complete. The fabled console message it describes never happens. Even so, please just send me a message that I can use syslog.conf to route to whichever logging facility I please. Sending something to the console only without possibility of configuring it to go somewhere else makes me very sad since I'm not going to be watching the console for hours at a time. Does anyone know how long the revert process takes? Our next problem is that now that we've vol-copied, the destination volume wants to upgrade itself. Again, does anyone know what the steps are and how long they take to upgrade? I found the following information in "vol status -c": turbine*> vol status -c Volume Checksum style Checksum status vol0_1 zoned Checksums active root zoned Checksums active vol0_2 zoned Checksums active vol2_2 zoned Checksums initializing: RAID upgrade phase 1 (of 2) in progress vol2_1 zoned Checksums initializing: WAFL upgrade in progress (BTW, wouldn't alphanumeric sorting be nice in output like this?) So is it the case that we have 2 RAID upgrade phases and then a WAFL upgrade? Are there more or less steps and what order do they come in? How long does each one take? Assuming the time is a question of the amount of data and beef in the server, we're talking about F840's working on volumes that are about 500GB big with 200-400GB of data on them.

NTFS Formatting
by Jessica Fernandez 11 Jun '01

11 Jun '01

I have a filer with UNIX and NT data. I want to move via ndmp to a larger filer. In preparation for the data move I read somewhere that in order for NT data to maintain security permissions, the destination must be NTFS formatted. Is this true, and how do you perform this if the host is a Unix machine but other NT servers are available. Also how would UNIX data fit on an NTFS format. Any help is greatly appreciated.
