Hello,
I have a redhat box with Hardware Raid. Below ar ethe outputs of various
files/commands. Please let me know whether there is anything wrong.
I think there might be some problem in md0, but I am not very sure.
Somone told me that since the box runs hardware the md-status does not
matter. What does the "[UU]" mean in mdstat ? In md0, one U is missing.
What should I do next ?
Kindly help me.
Regards,
Vijay Kumar.
