  Sharing / writing IIS Log files on SAN? Reply Contact HI all, we have started the testing phase for our web farm, while we have load balance servers and everything is working brillantly, we have the need to place all log files into one location on our SAN. So we have created a share and provieded the UNC on the log file location with IIS, this seems to be working in terms of writing to the directory which is great, but I can only see one server log anything. I am thinking because it is using the same file name and the log file is considered open the other server is also unable to open and write to it? If this is the case is there a way around this, or could I have each server append a prefix at the start or finish of the log file for example: orginal log file name : u_ex090114 prefix log file : Server1_u_ex090114 Any help here would be greatly appreciated.   - MCP - - MCTS -

You can call the log files whatever you want so rename them to server1_xxxx like you suggested before. Or better still think about writing to them via logparser to database every night. It will make your life some much easier. http://www.iisportal.com

Reply Contact Sorry I said that completely wrong you cannot change the names of the files I was thinking about the path directly above it. You will have to rename the files manually /scripts/ etc. Batch them daily is the simplest way. http://www.iisportal.com

  Re: Sharing / writing IIS Log files on SAN? Reply Contact Hello, The easiest thing to do to get 2 NLB servers to save their log files to the same directory, uniquely named by the server name, would be to schedule a batch script to run on each web server on a nightly basis to copy the log files to the destination folder, appending the source server name or other identifier to the log filename. Essentially, the script below copies domain.com's log files to the T:\ drive in it's own folder, and appends _serverA to the extension of the target file. Run the script on each web server, replacing the "_serverA" with the actual server's name to prevent them writing to the same files. XCOPY "C:\Inetpub\wwwroot\domain.com\logs\W3SVCXXXX\*.log" "T:\domain.com\*.LOG_serverA" /D /Y Hope this helps!
