RE: virus scanner
by Mike Sphar 02 Apr '03

02 Apr '03

When we first set ours up, we had the scan servers deregistering because of network errors due to speed/duplex mismatches. (Seems that no matter how often I tell everyone never use auto-negotiate it still keeps happening...) It's definitely worth double-checking the port settings and switch settings of all the systems involved just in case. In our case when the client deregistered, fixing the network problem didn't get the client to re-register, but rebooting the scan server fixed it. It's not clear to me why the loss of a scan server would increase CPU usage on the filer side. The filer is just sending scan requests to the scan servers. With only one server up it's still sending the same number of requests. Especially with those requests being non-blocking that doesn't make sense to me. In fact, it makes me more suspicious of a network issue. Certain types of network problems can cause significant cpu usage. -- Mike Sphar - Sr Systems Administrator - Remedy, a BMC Software Company -----Original Message----- From: Bui, Marcus [mailto:Marcus.Bui@aiminvestments.com] Sent: Wednesday, April 02, 2003 7:47 AM To: 'Merkin, David S'; 'toasters(a)mathworks.com' Subject: RE: virus scanner David, Yes, the virus scanner is on the same segment using Gig NIC.

RE: post-migration: sloooow response

I would start at the bottom and work my way up. So where is the bottom? Check physical and network layer type stuff. You mention no physical changes, but you have moved to layer 3, so it is a safe bet the problem is in there somewhere. Duplex mismatching maybe? Run netdiag -v on your filer and it will give you a pretty good analysis from the filer perspective. Check switches/routers for dropped packets, overflowing buffers and/or packet shaping. If you want to get down to the lowest layer and are good with packet headers/tcpdump, then do a packet trace on the filer (pktt) to a known good host and then to a known bad host (i.e. your ls hanging machine). I am betting netdiag or you switches/routers turn up something. If nothing shows there, work your way up to NFS/CIFS analysis.

quota question
by Charles Bartels 01 Apr '03

01 Apr '03

Hi, I have a question regarding quotas. I am accessing my home directory from both the UNIX and PC side of things and I have a number of entries in my quota file including a default quota. # Operations folks cbartels user@/vol/vol0/ops_home 7GB - * user@/vol/vol0/ops_home 3GB - When I do a "quota report" I see 2 lines which seem to refer to my account. The second line appeared after I edited and saved a file on the PC side. It seems like there are 2 separate quotas, one for unix files and one for pc files. I would rather have a single quota for all the files in the user's directory. Is there a way to do that? jupiter> quota report K-Bytes Files Type ID Volume Tree Used Limit Used Limit Quota Specifier ----- -------- -------- -------- -------- -------- ------- ------- --------------- user cbartels vol0 ops_home 1211688 7340032 10444 - cbartels user \cbartel vol0 ops_home 52 3145728 1 - Thanks. -Charles Bartels

converting a directory to a qtree
by Garrett Burke 01 Apr '03

01 Apr '03

Hi, Has anyone any experience of converting a directory to a qtree (we want to make use of the qtree to qtree snapmirror features in DOT 6.2 and greater) There's a doc on NOW which gives two ways either do a copy, which requires enough free space (which we don't have) or to use the built in ndmpcopy feature of DOT. There's also the possibility of doing a 'mv' on each file, although I'd be a bit concerned that this might leave the filesystem in a less than optiomal state on the filer. I'd be interested in hearing from anyone who has done this, especially about throughput (The directories we need to convert have approx 150G of mail in them, so lots of small files, on a 840C) Thanks, GB ---- Garrett Burke, Service Implementation & Support Manager, Eircomnet. http://www.eircom.net

RE: Windows Roaming Profiles on CIFS?

1 thought is that the User's ID must have full control at the share & file level of the profile on the server.
