Share Connection State after Renaming the Directory
by Merkin, David S 26 Sep '02

26 Sep '02

Hi NetApp Toasters: I am having an issue with a Share Connection that still stays connected after renaming the subdirectory that the share is using. For example if c:\vol\vol1\test is shared out as sharetest on filer1 and the test directory is renamed to c:\vol\vol1\test.old the share is still accessible. You should get an error that the share is not accessible. The only way around this is to stop the share and recreate it. In fact I thought it might be the workstation cache so I reboot the workstation and the same thing happens. I also tried this on several workstation OS's - NT 4.0, XP Prof. and Win2K but they all have no problem connecting. In Windows NT you get an Error Message that the share is not accessible if you rename the directory. If anyone has any information that would be great Thanks David

RE: Finding who has files open (in use)
by Mike Sphar 26 Sep '02

26 Sep '02

What I do when I get occasional reports of locked files is use a combination of "cifs sessions *" and "lock_dump -f". The cifs sessions command often shows files held open, and for some occasions where it doesn't the lock_dump command always has. Between those two commands I've always been able to identify the computer and user that has the file open. It's possible this information doesn't include nfs locks. I've never had a case of an NFS user interfering with other access to the file so it's never come up. (NFS locking is for the most part not enforced.) The output isn't pretty, but it's readable, and probably very parseable by something like perl if someone had a mind to do so. -- Mike Sphar - Sr Systems Administrator - Remedy Corporation -----Original Message----- From: Maglinger, Paul [mailto:PMAGLINGER@scvl.com] Sent: Thursday, September 26, 2002 3:24 PM To: 'NetApps list server' Subject: Finding who has files open (in use) Greetings toasters!

I want an output similiar to what you would see if you went into Windows Server Manager, selected the server and clicked on the "In Use" button, but I want something more user friendly than scrolling down looking for the file name.

LED on drives flashes from green to red
by Daniel Finn 26 Sep '02

26 Sep '02

I'm just wondering if this is normal and why it happens. I've recently been put in charge of admin'ing several F760s and am just starting to learm my way around them. I've noticed that some times the green LED will flash red for just a second and then back to green. This is on drives that are in use and getting quite a bit of I/O. Thanks Dan

RE: NDMP
by Mike Ball 26 Sep '02

26 Sep '02

The only issue I have ever ran into is with Networker. If you need to a restore for more than 1024 files you can not use DAR. The work around is to turn off DAR, rerun the restore and it works fine. Just keep in mind the restore will be slow because you will have to walk through the tapes sequentially until the files are fond. What kind of problems are you having? I have not had any major issues with either Networker NDMP or Netbackup NDMP. Both work well, although Netbackup does not have DAR capability yet. -----Original Message----- From: grey jolly [mailto:greyjolly@yahoo.com] Sent: Tuesday, September 24, 2002 11:44 AM To: toasters(a)mathworks.com Subject: NDMP Most of the folks we deal with have a lot of problems with NDMP.

RE: ndmpcopy question
by Chitre, Amol 26 Sep '02

26 Sep '02

Hello Prem, Yes, ndmpcopy can be used for data migration, and it works with full volumes, qtrees and even plain directories. But no single file ndmpcopies yet. Regardless of the granularity of your dataset to be copied, a limited number of incrementals are supported as well, so you will have to check the man page along with the ndmpcopy utility you are using for this. Hope that helps, Amol. -----Original Message----- From: Premanshu Jain [mailto:Premanshu.Jain@synopsys.com] Sent: Tuesday, September 24, 2002 5:17 PM To: toasters(a)mathworks.com Subject: ndmpcopy question I wish to copy a whole volume from naca:/source to nacb:/dest . Can I copy a qtree nacC:/vol/vol0/qtree to nacb:/dest/qtree..? Will the ndmpcopy be able to do the incremental later, if the case one is possible. prem

Re: SUN Solaris Performance Tools
by mds＠gbnet.net 25 Sep '02

25 Sep '02

BGS Best1's data collector has now apparently been combined with BMC Patrol so that (despite my personal dislike for Patrol) it might be a goer. TBYB. Alternatively simply using the various *stat's with some noddy bits of perl or shell-script will give useful date/time-stamped tables which you can then graph using spreadsheet software or gnuplot, and are quite amenable to importing into databases or packages like SAS. RRDTool is also a likely candidate for the kind of performance-tracking trending and capacity planning that you might want to do. RRDTool doesn't collect data though, just helps you work with time-based data. -- -Mark ... an Englishman in London ...
