Now, on my home box, If I run /bin/sync, the disk seeks, whether there is data to write or not. Before you point to me that I need to mount noatime - already done :) I think it also did this when bdflush told it to sync, but after installing noflushd (and hacking the b0rked init scripts), all was fine. At least, until I installed ext3 :( -- TimC -- http://www.physics.usyd.edu.au/~tcon/ Some witty text here, can be any number of lines long - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
