[Discuss] Is this bad?



Hi,

I finally turned on Smartd on one of my servers (don't ask me why it
wasn't on earlier), and I've been receiving messages like the following
every night.  Is this bad?  Is this a sign that one (or both) of my
disks is (are) dying and need to be replaced?

Could this be related to why when the machine is under heavy load that
ksoftirqd/1 starts spinning and taking up lots of CPU?  This is my
mythtv backend server, so it can have heavy disk I/O when recording
multiple HDTV streams simultaneously (upwards of 40Mbps at times).
