Can anyone answer this question:
What happens if one drive is out of sync with the other. One drive has 1 month newer files on it, but its not the boot drive.
If I let Centos boot from the older version will it automatically rebuilt the raid 1 to the second drive????? (bad for me)
Or do you have to manually do it??
With raid1 arrays, you don't actually boot from a partition, you boot from the raid array such as /dev/md0. The raid code should know if the array is out of sync and will leave the bad drive out of the array. Your array will be in degraded mode, but should boot. Then you can add the other partitions back to the array and they will re-sync. You just have to be careful that you add the proper partitions back to the proper arrays.
Okay here is another strange question. I have booted the system with ubuntu and mounted the good drive can I edit files on the boot partition to get it to boot?
I can see all the files but the fact that when the drive boots it says can file boot partition makes me suspect that I would have to do more than that. The partition is there /boot and it is set to boot.
So what your saying above that if I boot the system it should boot and nothing will be synced untill I do it manually?
