After a boot my raid 1 was degraded, and started syncing but gave an error on device 2 and started all over every time again.
So I replaced device 2.
After boot it started and finished syncing. And shows a status of 'optimal'.
But every time I reboot, the set comes up degraded, starts syncing until it is optimal again.
1) Could it be that disk 1 is bad as well?
2) Can I swap disk1 with disk2 (slots I mean), to see what happens, and will I not lose data?
3)What is the best approach to tackle this problem?
