I have a RAID0 volume two drives striped for speed and space.
I am suddenly getting alerts that the volume is "degraded".
One disk shows online and the other disk shows "degraded".
I don't get it.
A RAID0 can't be "degraded" it's either good or it's gone.
The disk itself does not show any problems or SMART errors/issues.
And of course the volume works just fine.
Any thoughts on what/why this is and how do I fix it?
I don;t care about the data on the volume.
It is temporary scratchpad storage space for nothing important.
Thanks!
