I think you can tune the sync speed via /proc/sys/dev/raid/speed_limit_min and /proc/sys/dev/raid/speed_limit_max using a SystemImager pre-install script (see /var/lib/systemimager/scripts/pre-install/README). Just set a small value for both options, in this way the complete sync will be done after the first reboot of your image.

You don't need to preload the raid1 module in the SystemImager initrd.img, since AFAIU the imaging process correctly creates the MD devices. > > Now this never came from a golden client!

Have you tried to add the raid1 module in /etc/sysconfig/mkinitrd and re-create the initrd in your golden client (by mkinitrd)? you also need to clone the image again by si_getimage. Otherwise, you could try to run mkinitrd in a post-install script, changing the /etc/sysconfig/mkinitrd directly in your image before (add the raid1 module to the modules list). IMHO this second approach is much simpler. -Andrea ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
