I mean, i did=20 nothing even after a read error on md0 with a "failed command: READ DMA= "=20 in dmesg (possibly because after a few reads it succeeded reading?). I=20 read that when raid1 is in doubt there is a 50%-50% chance it uses data= =20 from the good disk, wouldn't be better to fail the broken disk and then= =20 re-add it to the array?
