RE: Sun Solaris 8 optimal performance with F880
by Rainchik, Aleksandr (MED) 27 Sep '02

27 Sep '02

As far as I know, that 32k/UDP block size problem is specific to Cisco switches only. We had such a problem when our swithces were upgraded from 55xx model to 65xx. Huge performance problems with 32k blocks, had to change it to 8k. Try to use crossover cable and connect same client directly to the filer. You'll be surprised how well NFS with 32k/UDP packets works... -- a.r. -----Original Message----- From: Brian Long [mailto:brilong@cisco.com] Sent: Thursday, September 19, 2002 8:48 PM To: Deepak Soneji Cc: toasters(a)mathworks.com Subject: Re: Sun Solaris 8 optimal performance with F880 UDP and 32K transfers don't mix.

RE: Finding who has files open (in use)
by Bui, Marcus 26 Sep '02

Paul, Try Hyena from SystemTools http://www.systemtools.com/index.html. It's very useful, especially in a Windows environment. It can list all files open and can sort by filename or LAN ID. You can disconnect the user/multiple users or send them a msg. Also, can export to CSV file. This utility can do a lot more. cheers, Marcus Bui -----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!

There is command line utility that works from an NT Workstation. It shows the open files and it closes the files if you want. It also shows the file id and user who has it opened. It is called NETFILE.EXE. I am not sure if it shareware but you can try to e-mail brian(a)keene.net for a copy.

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)

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!

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.
