Snapshot access usage
by Rick Hulsey 05 Oct '00

05 Oct '00

Does anyone know of a way to tell if files in a snapshot have been used for recovery and how often? My guess is that this could be done by capturing file access statistics on the filer. We are trying to keep snapshots online as long as they are needed, but also trying to not waste space by retaining snapshots too long. If anyone from Netapp is listening and there is not a way to capture these statistics, it would be a good thing to add - Hint, Hint!

Has anybody been able to have Macintosh clients access a CIFS only filer without the use of Thursby's Dave software?

OnTap 6.0
by Lance R. Bailey 05 Oct '00

05 Oct '00

We have a pair of 630s that we've been trying to cluster for about 15 months. Downtime is that hard to schedule. We are upgrading to a pair of 760s, already clustered, hopefully next weekend. Because the upgrade from 5.X to 6.0 is lengthy (~ 1 hour i have heard) we are considering upgrading the pair to 6.0 before the move, otherwise it might be many months before I can schedule a downtime of even that hour. versions that are "anything.0" are always treated by me as ... suspect ... so I am looking for comments/experience on the stability of 6.0 - while i know that we can back out, i'm going to be lynched if the new filers turn out to be unstable. thanks. -- email: lance_bailey(a)pmc-sierra.com box: Lance R.

Being a rather paranoid and conservative old (censored), I generally like for my peers to whack on new things before I install it. But there it is! Multiple paths for cifs homes! Sooo, when do we think 6.[whatever] will be Recommended? -- Louis <l.brune(a)ericsson.com>

Re: Multiple cifs.homedir paths (Was: RE: Optimal volume size)

You are thinking of DFS (Distributed File System) available with NT 4.0 server. We use automount extensively and I find DFS very similar in design and function. We use DFS in production "with good success" according to the "NT camp".

I recall that there was a Microsoft made product which was essentially an automounter for NT. Does anyone know the name of the product in question, and have any experience with it? I would love to be able to point users at one location, and have them find the right toaster. Darrell

RE: Optimal volume size
by Clarke, John L. (CIS) 04 Oct '00

04 Oct '00

We have a similar situation on our F740. We want to keep the volume size small because: a) Restores can take forever as the data size gets bigger. b) 10-14 disks is a good compromise on reliability. Having 2 out of 14 disks go bad at one time is much rarer than 2 out of 51 disks. c) If you upgrade disks/shelves in the future, you will likely do it a volume at a time. We did this with a volume with 180GB and the volcopy took 6-7 hours to complete. It is NOT very fast. With 400GB+ in a volume, that should be 2-2.5x longer. John -----Original Message----- From: Moshe Linzer [mailto:Moshel.Linzer@nsc.com] Sent: Monday, September 18, 2000 4:31 PM To: toasters(a)mathworks.com Subject: Optimal volume size We are moving from a 630 with a single 350GB volume (51x9GB SCSI) to a new 760 with 14 36GB disks. Our Netapp support recommends creating a 14-disk raid group, with a single raid group per volume (giving us a maximum volume size of around 400GB). I understand why 14 disks is a good number for a raid group (balance chances of disk failure vs efficient use of disks), but what is the reasoning behind keeping volume size down to around 400GB? Is it just dependant on restore time from tape? In which case, as faster tapes become available (LTO?), this number should increase. Does it also lessen chances of file system corruption on the volume, or is it just a warm fuzzy feeling that all your eggs (so to speak) are not sitting in one 1.2 terabyte volume? If my max volume size will remain the single raid group, I would like to divide my data into 2 smaller volumes from the start, so I don't start off with a maxed-out volume. This means using a time-consuming ndmpcopy or rsync process to move the data, instead of the faster volcopy or snapmirror. Thanks for your insights. Moshe

unix Opnet licenses
by Frank Gilmurray 04 Oct '00

04 Oct '00

Does anyone out there run a unix Opnet license server on their filer? The Opnet licenses know where they're installed and if you restore a disk, they will no longer work (because now they're in a different place). I don't know of Opnet uses the inode number to do this or what.
