RE: Looking for drive space utilization reports
by Jay Newton 09 Jul '01

09 Jul '01

I looked real closely at the Highground stuff. There's a module called Prospector that will allow me to do what I need at the file level. I'm afraid that it's going to cost an arm and a leg, though. I haven't looked at BMC too closely yet but I will. Hopefully the price will be more attractive. Thank you all for your input. It has helped tremendously! -----Original Message----- From: Jeffrey Krueger [mailto:jkrueger@qualcomm.com] Sent: Monday, July 09, 2001 2:52 PM To: Honeycutt, Michael Cc: 'Coartney, Paul'; 'Jay Newton'; 'toasters(a)mathworks.com' Subject: Re: Looking for drive space utilization reports This is true Michael. DFM is a very nice multi-filer management tool and is tightly integrated with the filers. It has lots of useful reports, especially for multi-filer sites that are trying to find a chunk of free space or figure out how much they can expand certain filers. DFM will not do two of the things Jay asked for though - it will not tell you the type of data using the space, nor will it tell you which users are putting it there. It is more designed to be a multi-filer management tool than a storage management tool. Highground will (somewhat) do what Jay is looking for. He may also consider looking into BMC. They bill their storage management tools as being "Application specific" - that is they have a capability of mapping certain applications (like Oracle) to data usage. Like Highground, BMC has an agent-based architecture; however, I'm not sure of Highground's support for "Tier 1 storage". BMC has agents for monitoring NetApp as well as EMC Symetrix, Hitachi, etc. Good luck Jay! -- Jeff On Mon, Jul 09, 2001 at 12:02:35PM -0400, Honeycutt, Michael wrote: > The reason I suggested Highground is because it has the ability to monitor > "soft" quotas.

It takes forever and a day to remove a hundred or more GB off a filer from either CIFS or NFS. An "rm" in the ONTAP CLI would be super handy. It could work *much* faster then over the wire. Further, an "rm -F" to delete files through the active file system and all snapshots would even be keener. =) -- Jeff On Mon, Jul 09, 2001 at 07:59:53AM -0700, Fox, Adam wrote: > This comes up quite a bit.

The reason I suggested Highground is because it has the ability to monitor "soft" quotas. It wont enforce quotas on the filer, but it will e-mail users when they are close to reaching their quota. As far as I know, the Data Fabric Manager doesnt have this functionality.

CIFS Gigabit Performance?
by Ambrose_Earle＠shamrockfoods.com 09 Jul '01

09 Jul '01

Would anyone mind sharing the best throughput figures they've been able to sustain, for both writing and reading, to a filer via CIFS over fiber GigE? I'm trying to get a feel for what I should be able to attain. Also, any tuning suggestions would be most helpful. Thanks,

RE: how to manage entries in the auditlog
by Thompson, Tim 09 Jul '01

09 Jul '01

> From: Hannes Herret [mailto:hh@bacher.at] > anyone knows the behaviour, that the opened java performance tool from > na_admin logs in the auditlog every few seconds. > the auditlog grows and grows ..... > is it possible to disable the logging for the performance-tool? I don't believe it's possible to selectively disable the logging of that information. If java in your browser is capable of doing UDP to the filer, it will use SNMP rather than HTTP to get the performance data, and it won't be logged. But this varies from browser to browser, so the best way to deal with this may be to either periodically filter the auditlogs or avoid running filerview's performance tool continuously. Tools that get data primarily through SNMP, like our new DataFabric Manager, will not cause the auditlog to grow like this. I've entered a burt about this, thanks for noting it. ...Tim Thompson...Network Appliance, Inc...

NetApp has a new tool called Data Fabric Manager that may fit your requirements, and is a lot cheaper than highground.

RE: du -s after ndmpcopy - why are the filesizes different?
by Fox, Adam 09 Jul '01

09 Jul '01

I guess my question is how different were the results? A couple of percentage different is normal in dump/restore situations, which ndmpcopy is. Things like the restore making better use of blocks since it gets to re-write your data from scratch, etc. As far as verifying ndmpcopy, remember that ndmpcopy is just a native ONTAP dump/restore so any method you would use to verify your backups would also apply here. Most of them are not fun like what has been suggested of comparing file by file. If you trust your backups, you should be able to trust ndmpcopy. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Clawson, Simon [mailto:simon_clawson@mentorg.com] > Sent: Monday, July 09, 2001 8:11 AM > To: 'toasters(a)mathworks.com' > Subject: du -s after ndmpcopy - why are the filesizes different? > > > I ran an NDMP copy on my filer to take some qtrees from one volume to > another.

Mount the two fs's, cd into the root of your original fs (for arguments sake /mnt/orig) and then run a find over it. Let's say /mnt/new is the new fs: find . -type f -xdev -exec cmp {} /mnt/new/{} \; slip in a -print if you want to be sure it's examining everything along the way. I think you may need gnu find to do this, as not all vendor finds allow you to substitute in multiple instances of {}. I'm sure something reasonable can be worked-up in perl in about 10 lines, in an afternoon too. You could also use two separate finds to assemble two lists of checksums or md5 hashes and then compare them relatively simply with the various text utils unix provides. As for why they're different, I'm fairly sure a number of reasons have been mentioned over the years and are all in the archive or on NOW. And that's even assuming the files are all there and intact... if they've somehow suffered some problem then there's no need to get exotic. 8) hth On Mon 9 Jul, 2001, "Clawson, Simon" <simon_clawson(a)mentorg.com> wrote: > This message is in MIME format.
