Hi All,
A word of warning - OnTap 5.1 with its full NT ACLs has some problems. From bitter and ongoing experience I wouldn't advise using it on a production filer.
If you are running this I'd advise getting onto netapp to get the latest bug fixes. I have been advised to run whack. Still haven't dared switch quotas back on.
I used to think that those giving off about the quality of netapp SW were being a bit harsh, but now I'm not so sure. I know I'm running an early release, but never again. The troops will just have to wait for the new fetures.

Hello,
I've just upgraded the OS from 5.1 to 5.1D3, which includes patches for the problems mentioned below. Basically, everything is working fine now ( so far). One of the nice things about a netapps box is that problems are manifest early on and can be tackled quickly, instead of lurking in the background and appearing just when you don't need them to.
BTW, what does "run whack" mean ?

Garrett was running 5.1. The problem he has seen is fixed at 5.1R1 (and 5.1D3).

Could you elaborate? What problems are you having?
Are you running 5.1R1?

Hi All,

filer panics every few mins when CIFS is running. I understand from netapp that it's a problem with the NT ACLS being written to the wrong volume (I'm running two volumes, but only one actually has NT ACLs applied in it) I would have thought that multiple volumes was a pretty obvious thing to check for in QA.
Also there's a quotas problem that panics the filer when you do a quota resize. Quota on/off is ok though.
These problems aren't in the bug lists on NOW yet.
Are you running 5.1R1?
I'm now running 5.1D3 (debug release) which apparantly fixes the above problems, but I may have a corrupt file system. (paniced due to an assertion last night during backup). I'm running wacky later this evening on the advice of Netapp support to see what's wrong and they have 5 core files to sift through as well. (2 for the quotas problem, 2 for the NT ACL problem and one for file panic probably due to a corrupt file system)
Frightened yet? 8-)
You using CIFS heavily Graham?

I'm always frightened. Things are just getting out of control. Too much data, too many users. Argh!

Not yet, but i will be. My tech support guy alerted me a few days ago to upgrade from 5.1 to 5.1.D3 (which i think is basically the same as 5.1R1) We will be using mixed volumes pretty much exclusively.
I haven't seen the same problems you have, but we are still testing the small things - i haven't put it through any stress tests yet - sounds like you have. Please keep us up to date with your problems - i'd really like to know if the software upgrade fixes them.

I thought I had done enough testing as i had moved some stuff ~500MB and 4 users to the toaster (The sysadmins incl myself & my boss!), but the problems only hit when I moved 3GB over to the toaster and 40 users connected within a few mins.
Please keep us up to date with your problems - i'd really like to know if the software upgrade fixes them.
I back running with snapshots & quotas on 5.1D3 and even managed a backup.
I ran wacky on the filer as recommended by support, but it didn't make any changes to the file system.
Fingers crossed it's ok now.
