I've gone through this upgrade a handful of times, and it can be pretty tricky. It would be best if the data array were not assembled over and over again during the process. I know it really shouldn't make a difference, but in the real world stability issues have raised their ugly heads more than once causing additional time and heartache associated with the array to be required to complete the task. With this in mind, I would like to temporarily disable the assembly of the array until the upgrade is complete and the system stable. Do I have the following checklist correct, or is there something wrong or missing? Are there better alternatives? I'm not missing something about the "homehost" utility, am I? 1. Edit /etc/mdadm/mdadm.conf and comment out the line specifying the array. Also comment out the line "HOMEHOST " 2. Edit /etc/fstab and comment out the line specifying the mount point for the array. 3. Issue the command `update-initramfs -u` 4. Reboot the system, making sure the array does not assemble. 5. Perform the OS upgrade. 6. Edit mdadm.conf and fstab, removing the comment markers placed in steps 1 and 2. 7. Issue the command `update-initramfs -u` 8. Reboot the system, making sure the array assembles and mounts.
