do not abuse a filer as a door stopper! but get an iSCSI license, it's free create a virtual disk mount that from a Windows Server 'share that folder' works with Linux as well do not abuse a filer as a door stopper!

RE: Maildir + netapp performance tuning?
by Jeff Mohler 15 Feb '06

If you have support, please feel free to open a case, and with perfstat they can take a glimpse at what is going on and tell you why its like that. If you get a case open, I will also gladly give it a quick peek as well. -----Original Message----- From: owner-toasters(a)mathworks.com on behalf of Adam McDougall Sent: Tue 2/14/2006 9:12 PM To: toasters(a)mathworks.com Subject: Maildir + netapp performance tuning? Does anyone have any tips for tuning a netapp (and/or clients) for nfs access to Maildir email folders? I know people do it, and potentially the load on the server(s) could be less than mbox because you arent shovelling around huge files, but it seems like the netapp is a little slow with opening a larger number of files for reading one by one. By large I mean over a few thousand (three to 130 thousand I have tested with) and slow I mean between 200 and 500 headers read per second from nfs. It is only slow if the filer does not have it cached already, because followup folder opens get several thousand headers per second throughput, similar to mbox. I have not tried other nfs servers, but I have attempted to simulate the load from courier-imapd or dovecot using a shell script to read 2 dozen lines from each of several thousand mail files, and the delay seems to be the netapp. Additionally, if if is a fresh folder open (not cached anywhere), the first 2,000 or so message headers load quickly, it slows down to between 200-500/sec for the next few thousand, and if you let it get above several tens of thousands, it continues to slow even more, down to less than 100 headers per second. I am somewhat dissapointed that the NOW forums and documentation is pretty much devoid of any mention of Maildir, let alone tuning for it. I have a FAS940, not heavily loaded, and the clients for this are a small cluster of Dell Poweredge 2650 dual 2ghz xeons, running in pre-production environments of either Debian Linux or FreeBSD 6.x. The filer is running 7.0.3, and the files are stored in a flexvol in an aggregate spanning 3 DS14's full of disks (28x36, 14x72).

We have just received in donation a couple of FC9 shelves. I found a F720 on ebay for cheap and now I am attempting to start the things. I have got the units attached via the FC cable and booted to the 2 floppy disks provided but I can not seem to attach to the hidden share from my windows PC or mount the file system from a linux box. Am I missing something vital. I have also received all sorts of documentation that appears to be no help. thanks in advance, Basil Istwany

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.

But how is uptime with Microsoft Windows Storage Server 2003 and max volumes performens and so on? The arguments that we have is the cost otherwise, we are complete happy with our fas940 and r200.

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
