RE: du -s after ndmpcopy - why are the filesizes different?
by Fox, Adam 09 Jul '01

I guess my question is how different were the results? A couple of percentage different is normal in dump/restore situations, which ndmpcopy is. Things like the restore making better use of blocks since it gets to re-write your data from scratch, etc. As far as verifying ndmpcopy, remember that ndmpcopy is just a native ONTAP dump/restore so any method you would use to verify your backups would also apply here. Most of them are not fun like what has been suggested of comparing file by file. If you trust your backups, you should be able to trust ndmpcopy. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Clawson, Simon [mailto:simon_clawson@mentorg.com] > Sent: Monday, July 09, 2001 8:11 AM > To: 'toasters(a)mathworks.com' > Subject: du -s after ndmpcopy - why are the filesizes different? > > > I ran an NDMP copy on my filer to take some qtrees from one volume to > another.

Mount the two fs's, cd into the root of your original fs (for arguments sake /mnt/orig) and then run a find over it. Let's say /mnt/new is the new fs: find . -type f -xdev -exec cmp {} /mnt/new/{} \; slip in a -print if you want to be sure it's examining everything along the way. I think you may need gnu find to do this, as not all vendor finds allow you to substitute in multiple instances of {}. I'm sure something reasonable can be worked-up in perl in about 10 lines, in an afternoon too. You could also use two separate finds to assemble two lists of checksums or md5 hashes and then compare them relatively simply with the various text utils unix provides. As for why they're different, I'm fairly sure a number of reasons have been mentioned over the years and are all in the archive or on NOW. And that's even assuming the files are all there and intact... if they've somehow suffered some problem then there's no need to get exotic. 8) hth On Mon 9 Jul, 2001, "Clawson, Simon" <simon_clawson(a)mentorg.com> wrote: > This message is in MIME format.

du -s after ndmpcopy - why are the filesizes different?
by Clawson, Simon 09 Jul '01

09 Jul '01

I ran an NDMP copy on my filer to take some qtrees from one volume to another. When I ran du -s on each directory the results were different in most cases. The question I have is - Is NDMP copy the tool for the job, and how do I verify the results once I have run it? Any ideas?

how to manage entries in the auditlog
by Hannes Herret 09 Jul '01

09 Jul '01

hi folks, anyone knows the behaviour, that the opened java performance tool from na_admin logs in the auditlog every few seconds. the auditlog grows and grows ..... important information 'vanishes' in the df-loggings. now the question: is it possible to disable the logging for the performance-tool? if not, maybe this useless logging will be disabled in the next ontap-release. cu hannes

RE: ndmpcopy levels
by McCarthy, Tim 06 Jul '01

06 Jul '01

If you use jndmpcopy, or ndmpcopy which has the "level i" option compiled into it, then you simply specify "level i" instead of your level 0 or 1 or whatever. This "level i" is maintained separately from the the regular dumps and ndmpcopy. --tmac -----Original Message----- From: Lance R Bailey [mailto:baileyla@pmc-sierra.com] Sent: Friday, July 06, 2001 12:14 PM To: Roger.Leonard(a)marconi.com Cc: toasters(a)mathworks.com Subject: Re: ndmpcopy levels standard berk-dump: level 1 will catch all since level 0. you can do this repeatedly. level 2 will catch all since levels 1 or 0. you can do this repeatedly. level 3 will catch all since levels 2, 1 or 0. you can do this repeatedly. you can run a level 1 *AFTER* and catch all since the last level 0.
