Oops,
seems i forgot about spares :(
multipath.c sets all disks as spares to start with.
a dirty hack could be:
look for:
/*
* Mark all disks as spare to start with, then pick our
* active disk. If we have a disk that is marked active
* in the sb, then use it, else use the first rdev.
*/
below you will find:
if (disk_active(desc)) {
if(!conf->working_disks) { //remove this line
printk(OPERATIONAL, partition_name(rdev->dev),
desc->raid_disk);
disk->operational = 1;
disk->spare = 0;
conf->working_disks++;
def_rdev = rdev;
} else { //remove this line
mark_disk_spare(desc); //remove this line
} //remove this line
} else
mark_disk_spare(desc);
remove the lines i market with //remove this line
and it should activate the disks
i wont have a system at hand to test this, so please let me know
if it works
we then need to clean up the logic for initialization
since is nonsense to set a disk as spare then reset it back
again as operational, but this could work for a start
good luck
