hi i make a read balance select (via sysfs), could anyone help me to debug it? the new/old code is located at: http://www.spadim.com.br/raid1/ it's kernel 2.6.37 based ============================================= i don't know if exist a function at per mirror bio queue that return the sum of write sectors, sum of read sectors, the first and last sector position in queue if anyone know please help me, i will use it at line: 510 raid1.new.c time_based_current_queue_time = 0; all information is in the same line ============================================= i don't know how to read information per mirror for example, at raid1.h i have some variables: int head_distance_rate; /* used by time based, time=(this_sector - head_position) * head_distance_rate */ int read_sectors_rate; /* used by time based, time=sectors * read_sectors_rate */ int write_sectors_rate; /* used by time based, time=sectors * write_byte_rate */ i would make it per mirror, for example: /sys/block/md0/md/sda1_head_distance_rate -> head_distance_rate /sys/block/md0/md/sda1_read_sectors_rate -> read_sectors_rate /sys/block/md0/md/sda1_write_sectors_rate -> write_sectors_rate anyone know how to do it? how could i compile the raid1.c and raid1.h to test? my today raid1 is a module at my current kernel, but i couldn't (i don't know how) compile it and use :/ it's my first kernel driver :) hehe -- Roberto Spadim Spadim Technology / SPAEmpresarial -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
