[Ocfs2-users] Any suggestions how to copy between two OCFS2 volumes faster?
I need to copy a number of volumes from one SAN to another SAN. Most of our volumes are snapclone based, so moving those has been easy. But we got several 700GB volumes, which I can't move that way. Doing an umount/mount local (no network lock?) doesn't seem help, speed is only about 20MB/sec using rsync. Any suggestions how to maybe copy faster? These are all Oracle RAC 10g database files. Ulf.

Try "dd bs=1M iflag=direct" on few files. See if that helps. On 06/15/2011 01:00 PM, Ulf Zimmermann wrote:> I need to copy a number of volumes from one SAN to another SAN.
