Maybe this?

I can recommend this, I run it on many petabytes of data successfully ( and not all of it netapp ).

Simon is always very responsive and helpful.

I just issued my first "vol copy" operation. It's running just fine as it copies a 1tb volume. I originally tried a flexclone split but after 15 hours it was only 6% complete.

As I read the cmd ref guide I saw that you can run 4 concurrent "vol copy" cmds, and there is a "vol copy status" cmd to monitor progress. From this I assumed a "vol copy" was a background process. When I issued the "vol copy start" on the console the prompt never returned - the copy seems to be running in foreground on the console. That is, the console prompt doesn't look like it will return until the copy completes. This surprised me! It spits out status msgs ever once in a while, and I can issue status cmds via rsh.

q) How do you get a "vol copy" command into background processing?

(OnTap v7.3.6)

Thanks!

On a related question, anyone know of a script or tool that can do this for nfs ? We have a few non-netapp nfs systems hosting archives (~330TB auto-mounted into a single namespace), that we would like to gather age distribution stats. On the windows side we use TreeSize, but it doesn't scale beyond 20TB. Doing that over samba is very slow.

Hi folks,

If anyone is interested I wrote a "Find" class in ruby with all of the features of the Unix "find" command and a few more:

1) access to parent directory chain

2) save/accumulate information during the find

3) post-process a directory after traversing it

4) terminate traversal at any time

5) supports multiple processes or Ruby threads

Probably doesn't work on Windows, only Unix.

The standard Ruby "find" is pretty rudimentary. It consumes TONs of memory if run in a large directory tree (breadth-first search) and it returns file pathnames as strings.

My find uses depth first search (only needs memory for the current item and the parent directory chain) and it returns a "Find" object with many useful methods, including "stat" information via Ruby's File::Stat class.

Here is a simple Ruby script that implements Unix "du -k" with my Find class:

Usage: du.rb dir ...

===========cut======== #! /usr/bin/ruby

include("./find.rb") # file not included in this email

top = Find.new

# register callback code to run after traversing a directory

top.postprocess do |dir| printf(dir[:total] / 2, " ", dir.path, "\n")

# add our total to our parent directory

dir.parent[:total] += dir[:total] if dir.parent end

# Run the find, which passes a "Find" object to the # block of code for each item in the directory tree

top.find(ARGV) do |f|

# This is a netapp, so we avoid .snapshot folders

if f.name == ".snapshot" f.prune next end

# accumulate disk usage (512 byte blocks)

if f.stat.directory? f[:total] = f.stat.blocks elsif f.parent f.parent[:total] += f.stat.blocks end end =============cut=======

Dear List,

I am trying to get file size and age distribution stats per volume on a Ontap8.1 system. Apparently, "filestats" command was removed on Ontap8.1 as "filestats" relies on java and java was removed on 8.1.

Does anybody know of any quick ways to get this kind of stats on 8.1?

Regards,

Ken Kawakubo Seattle
