RE: add bigger disk into raidgroup with smaller disks
by Fox, Adam 10 Jan '07

10 Jan '07

Yes, I can confirm that. But that doesn't *replace* any of the 50GB disks, which is what I understood as the original question. The rules are different if you add a disk vs. fail out a disk. If you were to fail out one of the 50GB disks in your scenario, and only a 100GB disk was available, WAFL would only use 50GB of the 100GB disk and even if you failed out both 50GB disks, the two 100GB disks that replaced them would still be 50GB. That's the catch. -- Adam Fox NGS Tools Developer adamfox(a)netapp.com -----Original Message----- From: Glenn Walker [mailto:ggwalker@mindspring.com] Sent: Wednesday, January 10, 2007 5:07 PM To: Willeke, Jochen; tmac; Fox, Adam Cc: toasters(a)mathworks.com Subject: RE: add bigger disk into raidgroup with smaller disks I can't seem to shake the memory of one other rule - if you add a 3rd disk of larger size, the extra space DOES get used. At least it used to be like that in the past, and I assume WAFL hasn't changed. For Example 100GB DP 100GB P 50GB D 50GB D Then add another 100GB data disk and it _should_ look like: 100GB DP 100GB P 100GB D 50GB D 50GB D Can anyone confirm this?

Looking for Beta Testers
by Harry McIntosh 10 Jan '07

10 Jan '07

Hi Toasters: We have a new software product for use with filers, and we are looking for beta testers for it. We can offer a free license for the product to a limited number of beta testers. The product is named Folderscape, and is a combination of Windows Explorer and FilerView. For details, please visit our website at Folderscape.com. Although future versions of Folderscape will include Unix functionality, the current version works only with NTFS volumes. If you have NTFS volumes, and would like to beta test the software, please let me know. Thanks, Harry McIntosh PAC Software, Inc. -- View this message in context: http://www.nabble.com/Looking-for-Beta-Testers-tf2955517.html#a8267591 Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

So berkcom.net redirects to zerowait - a 3rd party netapp reseller (used stuff?)... and the guy that emailed me\the list in response to the query just _happens_ to know a vendor? Convenient! Sounds like a sales pitch :-) Glenn ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Timothy Naple Sent: Wednesday, January 10, 2007 4:26 PM To: toasters(a)mathworks.com Subject: RE: Net app support This post by "Jack" (admin(a)berkcom.net) has nothing to do with us here at Berkeley Communications.

Hooked us up with a spare head on-site for less than a kit o' parts, which will make swapping out a lot faster in the event of a serious failure. Nice folks to work with.

No. You can't replace disks in an aggregate that way. If you do, they will sized down to the size of the disk they replaced. -- Adam Fox adamfox(a)netapp.com -----Original Message----- From: Willeke, Jochen [mailto:Jochen.Willeke@wincor-nixdorf.com] Sent: Wednesday, January 10, 2007 3:12 PM To: toasters(a)mathworks.com Subject: add bigger disk into raidgroup with smaller disks Hi toasters, currently i am testing with my simulator and searching for a way to do the following: - have a raidgroup with 5 disks - the two parity-disks plus one data-disk are 100 MB (net) - two other data-disks are 35 MB (net) I want to replace the 35MB-disks with bigger ones, but everything i tried left the "new" disk in the raidgroup with a used size of 35MB.

Netapp support
by Coder, James (STP) 10 Jan '07

Looking at other options other than netapp for hardware / software support - was wondering who others on the list are using - both stateside and outside the US (OUS). Netapp seems a little too rigid in their pricing / support structure. Thanks in advance for replies. Jc James C.
