Hi Phil, Wols, (Sorry for the top-post in my last reply). I'm working through everything Phil recommended. I am also using overlays exactly as documented on the "Irreversible_mdadm_failure_recovery" wiki. Things look very favorable so far. A quick question on what I'm doing? As per Phil's suggestion to put the array inside partitions, I have created partitions inside each of /dev/mapper/sd[bcde]. The gdisk operations end with the message: Warning: The kernel is still using the old partition table. The new table will be used at the next reboot. The operation has completed successfully. My question is how to get the kernel to recognize the /dev/mapper/sd[bcde]1 partitions I have created? Rebooting doesn't do anything as the overlay loop files aren't something that gets recognized during boot. Thanks, DJ
