I have a RAID-1 array on my system and since I installed fedora 16, the array very often starts with only 1 out of 2 mirrors:
[ 15.501909] md: raid1 personality registered for level 1
[ 15.502274] md/raid1:md1: active with 1 out of 2 mirrors
It is always the same mirror that is missing.
The array never had a single problem with fedora 15.
What could be causing the problem and how can it be fixed? It takes 4 hours to rebuild the data and having to manually rebuild the array at each boots pretty much defeats the purpose of having a RAID-1 configuration.
