Hmm - I honestly have never noticed that problem on any of our equipment... How long does the spike last? What version of ONTAP? VSM or QSM?

RE: Macintosh users can't see network drive

You might want to capture a quick packet trace on either the MAC or NetApp side (tcpdump on mac, I believe and 'pktt start all -d <directory>' on the Filer - be sure to perform 'pktt stop all' when done with the test).

ndmpcopy, jndmpcopy and multiple level 1 transfers
by Paul Letta 13 Nov '06

13 Nov '06

I am getting ready to do a big data migration. I am planning on doing an initial level 0, and then multiple level 1's leading up to the big day. I know the that native ndmpcopy in OnTap 7.1 can only do one level 1, and one level 2 for each level 0. But I have read that if you get ndmpcopy or jnmdpcopy from ndmp.org that it supports multiple level 1 dumps based on the same level 0. But I am getting the same errors I got with the native ndmpcopy when I use ndmpcopy and jndmpcopy from a unix host. I just grabbed the latest copies for ndmp.org yesterday. > java jndmpcopy.JNdmpcopy -version java version "1.4.2" gcj (GCC) 3.4.6 20060404 (Red Hat 3.4.6-3) So I did a level 0, and then one level 1 that both worked just fine. Then I re-ran the level 1 with the same command, and get the errors below. This is the same error I get if I try this with the native ndmpcopy command on the filer itself. I am moving about 1TB of data (about 16M files) off of 1 traditional volume onto multiple new flex vols on the same filer. If what I'm doing is flat out wrong, what would others suggest ? tar wouldn't give me the incrementals and rsync would take a long time with this number of files. Suggestions ?

Re: ndmpcopy, jndmpcopy and multiple level 1 transfers

Never underestimate the power of rsync. Here is what I did to move about 70mil files (lots of tiny files). With lots of tiny files, NDMCOPY spends a lot of time before it really transmits anything. In some cases of 10+ mil files on a busy filer I was waiting 4+ hours for files to begin copying (actual data, not just writing out sparse files for inodes). I found that if I ran a level 0 ndmpcopy on the weekend or during your off hours you can let it beat up the filer a little bit (and it will beat up both CPU and Disk util). Then, during the week run rsync's with --delete to keep things nicely in sync. This is something ndmpcopy can't do (I think).... if you do a level 0 + level 1 you won't get deletes. Doing the "catchup rsync's" gives you a good judge of timing on how long it will take you when you schedule your real outage. I recommend using rsync 2.6.6 or higher as it has significant memory efficiency compared to older versions. I used a 4 CPU Sun V440 to move a lot of data with rsync. Running a single process with a 16 million file list consumes as much as 8GB ram. I almost never found myself CPU bound and I found that CPU on the filer was much lighter than if I was doing an ndmpcopy. All of this depends on your rate of change for files, but overall I think rsync was faster for me after that initial copy. Since rsync wasn't using all my CPU, I broke it into an rsync for each top level directory, as many as 70 rsync processes in some of my migrations at the same time. This allowed me to sync up 16 million files in < 20 minutes in some cases. I suspect the level 1 ndmpcopy would be slower than that, but I'm not 100% sure. At the time of cutover, change the export to be read-only to block people from making change. This doesn't work if you have a subdirectory that is hitting a different export line. In this case I would do a second rsync and see what files were still changing and hunt down apps writing to that volume still.

To do this you must use a level 2 copy. I agree with the spirt, but I would rephrase it. :-) A level 1 *does* copy all the files that have changed since the previous level 1. It's just that they are a subset of files modified since the level 0 which are copied as well. So running a level 1 on the last day should take about the same amount of time whether any other level 1 copies had been run previously or not.
