OK sorry to hammer the list but one more question - having almost got the drives mirrored and happy - since I have created a custom initrd that has the raid1 drivers in it, do I now have to tell yum to ignore kernel updates? Will the stock kernel render me unbootable? Actually I am not 100% sure the initrd I created # mkinitrd -f --preload=raid1 /mnt/tmp/initrd-`uname -r`.img `uname -r` is even being used, because lsmod still lists a raid1 module. Wouldn't it be "embedded" in the running kernel and thus not in the module list? either way I am a little confused and this is important ;) best regards and thanks to all for the help, Sam _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
