RE: Maildir + netapp performance tuning?

Not specifically for Maildir folders, however I have recently read through the following document: http://www.netapp.com/library/tr/3183.pdf I've adopted the various tuning options as per that document such that my Linux clients now mount the various exports with options: noatime,rw,hard,intr,addr=<ip_address>,rsize=32768,wsize=32768,tcp We recently took a new customer-facing system live and found that, whilst using UDP with no real tuning, we were getting errors of the form: kernel: RPC: error 5 connecting to server <ip_address> kernel: lockd: couldn't create RPC handle for <ip_address> on the clients. We also experienced some slowdowns and stutters on the clients when under load, even when re-reading the same file over and over again - indicating network-related problems (although it's a clean gig ethernet LAN). Switching to TCP made it all so much better in termns of performance. In terms of MUA performance I'd be wary of letting any old MUA load up "several tens of thousands" of headers as you could well find yourself experiencing heavy IO on the client running the MUA at that point due to paging or swapping. I know I experience slowdowns on my old-fashioned personal mail system which runs mbox format (at the moment) on an EXT3 filesystem, but it's simply a function of the mbox being so large that it's fragmented on disk and that the client MUA I run only has 256MB of RAM and has to do a lot with it! In tests you might find you need a lot of RAM on a system doing nothing but IMAP access in order to keep a level playing field. I'm not entirely sure you could do that much tuning on the filer which would be specific to Maildir format itself, to be honest.

Snap Manger / Space reserve
by Willeke, Jochen 13 Feb '06

13 Feb '06

Hi everybody, i am new to the whole netapp topic and right now i'm a little bit confused. Currently we run a FAS920 with a LUN for our exchange database. We use snapdrive and snapmanager to take snapshots of this system and here is my problem. As i was told LUN's do not need a "Snap reserve" in the traditional way so i changed this setting to 0%. What i am wondering now is the output of df -hr total used avail reserved /vol/exchdata 700GB 428GB 271GB 89GB The Lun is currently at 330 GB so i expected the reserved space to be 330 GB too, because i learned with LUN's it is the default and recommend setting to have it like that. Can anybody help? Where does this 89 GB come from and is there a command to see how much space is currently reserved for this LUN? Rgds and thanks in advance Jochen

Jochen, The 89 GB is what is currently being reserved. The reason it is a lot less than 330 GB is because your actual exchange database is probably only about 89 GB. NetApp is sparse in nature, meaning even if you create a 330 GB lun it does not actually go and create a file 330 GB large.
