What would be the command to specify a buffer when using dd?
"dd -help" does not show such a usage.
"bs".
dd if=/dev/sdX of=/dev/sdZ bs=10MB
It is about the first item in the man page :-)
And on such a big copy job, I would try "oflag=nocache". Perhaps "direct". Otherwise, it eats the cache and the machine becomes unresponsive. Of course, if it is the only thing you are doing, it doesn't matter.
If you ever truly want a buffer, not just a block size, mbuffer (http://www.maier-komor.de/mbuffer.html) is a great tool. It is in the distribution. Greg -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
