So I started experiencing a problem (at least I think it is) with an Hitachi hard drive. unRAID has been running flawlessly for several months until this, no hardware changes.

 

I noticed the problem while watching a HD movie while attempting to seek ahead, XBMC would stall for a couple of minutes and then return. Each subsuquent seek ahead for this particular movie was taking that long a time. Seek aheads are usually quick, so something's up.

 

I traced down the movie to a particular disk and walked to the server and noticed the LED on my supermicro box for that disk was blinking ferociously, though a little dimmer than normal disk activity. And it would do this for each time I seeked ahead.

 

Thoughts?

 

EDIT: in the process of running a reiserfsck on the disk:

Maybe it's the file? Does it do this for other movies on the same disk?

Attach a syslog.
