Yes. The command "CIFS sessions" returns the list of clients and the number of files they have open. The command "CIFS sessions clientname" returns the full file path on the filer that clientname has open and the kind of open. --sam -----Original Message----- From: Clawson, Simon [mailto:simon_clawson@mentorg.com] Sent: Friday, January 25, 2002 6:35 AM To: 'toasters(a)mathworks.com' Subject: Whos got that file?

NetShield scanner can't register
by Paul Autore 24 Jan '02

24 Jan '02

VSCAN Gurus, My F720 filer (6.1.1R2) is showing the following message: "Virus scanner "IP-address" attempted to register but had insufficient privilege." Since I don't have any registered scanners, I still have left vscan off. My scanner is a Dell box running 2000 Advanced Server. I have McAFee NetShield 4.5 for NT and 2000 installed, along with Service Pack 1 that comes on the NetShield 4.5 for NetApps demo CD. On top of this, I have NetShield for NetApps installed. My scanner is on the same … [View More]

Gigabit ethernet performance
by Hsueh-Mei Tsai(May Tsai) 24 Jan '02

24 Jan '02

Does anybody knows what kind of performance I can expect from using the Gigabit ethernet on Solaris/NetApp? For example, if mkfile 1024m 1gbfile on a NFS mounted netapp volume thru the gbit interface, how many seconds of response time is considered to be reasonable? I'm getting about 30secs, while I'm hoping within 12secs, am I dreaming? Thanks, -May --

unix style to ntfs and back
by neil lehrer 24 Jan '02

24 Jan '02

hi, i have a question about security style reversion. we converted a unix qtree to ntfs and applied acls. there was a problem and i had to revert back to the unix style almost immediately after creating the acls. now i want to convert the same qtree to ntfs again. the question is will the acls that i originally put in place still be there after i convert to ntfs? the unix perms were there when i went ntfs back to unix, but it may not be the same going from unix to ntfs. anybody ever seen … [View More]

"Open files" in NetApp shapshots
by Joseph Foy 23 Jan '02

23 Jan '02

I am running a Network Appliance Filer and using CA ARCserve to backup files on a Windows 2000 network. All file access is working fine, and ARCserve seems to be backing up files on all other Windows systems OK. My problem is that ARCserve keeps reporting skipping (some)open or locked files even though I am backing up a snapshot (usually the last hourly.0 snapshot). Any thoughts on why ~snapshot\hourly.0 isn't acting as a read-only filesystem? Joseph Foy/Sys Admin/World Wide Packets/Beaverton Oregon

RE: Gigabit ethernet performance
by Surlow, Jim 23 Jan '02

May, One course I took at USENIX over a year ago, there was a comment from the system & network tuning course that said that it would take 3 CPUs (Sparc 300MHz) to saturate a GBIC. This was an unverified rule of thumb at the time. (I went back to my notes to dig this up). These days, you would have faster buses and faster CPUs, so adjust the number downward accordingly. In the case of the mkfile that process is going to be designated to a single CPU. Just for fun, you might want to … [View More]

RE: Repost: wafl scan question
by jwitham＠takedapharm.com 23 Jan '02

In our case, it's an exploding M$ Exchange Information store... It started out on 2 36G disks, now it's up to 4. Mailbox quotas must be nice... I was turned on to the wafl commands by one of our local PSE's last week, we were having horrible performance reported while our Exchange snapshot verifications were running. A statit showed 1 disk at 100% activity, and the next one at 66%. I ran a 'wafl scan measure_layout', and got: wafl_filesystem_sca:info]: WAFL layout ratio for volume vol7 is … [View More]4.87. (A ratio of 1 is optimal). So, I run a 'wafl scan reallocate vol7', let it chug for an hour, then run another 'wafl scan measure_layout', and it's still 4.87 :( I've done this twice now, with no change in waffling. We're running 6.1.2. At the advice of my PSE, I'm opening a ticket with NOW.
