Hi,
Ik accidentally discovered that my software RAID5 array was degraded:
one of the three disks had been kicked out of the array.
It appeared that disk /dev/sda1 had been disabled 5 days before! I was
totally unaware of the problem, which is odd.
syslog shows the moment the array got into trouble:
