Fastest Copy Method

[David Poe_2]

I ended up testing the above 3 streams of dd. I also tested one with 5 streams. I found that I was able to match the speed of my cp once I was moving significantly more data than buffer cache could hold for the cp. 3 streams saturated the IO for the server so as expected the 5 streams did no better. I would imagine that the higher class of Itanium servers I'll be doing this on will take more than 3 streams of data. Thanks everybody for your help and suggestions!

Hi!

... and how about putting new disks into old VG, mirror volumes, and detach all old disks?? At the end increase new lvols to desired size... all without stopping Applications... ;o)

The problem is that the VG's were improperly sized and we are now hitting those size limitations. Thank you for your suggestion though!
