This is a strange one here and unfortunately I need help.  To sum it up, one of my data drives is reporting as disabled after the system became unresponsive during a parity check. 

 

Now, the long story:  I finally had my unraid server all put together how I wanted it and decided to stress test the hardware to find any issues - well I guess I did.  I started the array (7 data, 1 parity) in maintenance mode and ran a non-corrective parity check (I figured no sense in hosing things if an error killed my parity).  That was last night, parity check ran for about an hour with 11 more hours until completion so I went to sleep figuring I would wake up in the morning and check things out before work.  I was logged in remotely last night on my laptop to monitor the temperature, any errors, etc during the parity check and left it on.  In the morning, the unraid web interface was unresponsive and the server couldn't be reached. Unfortunately, I had booted the server up into no GUI with the framebuffer disabled for VM reasons so I could not see what had happened and was forced to do an unclean shutdown (power button had now effect).  When it booted up (this time with the GUI and framebuffer enabled), the array showed disk 1 as disabled and I am at a loss as what to do.  The drive is present in the array, just disabled.  I'm nervous to do anything until I know what to do first.  Also, I would really like to have any suggestions as to what could have caused this.  I can imagine the logs are lacking as they were pulled after I was forced to power down the server so all of the details are missing from the time of the incident.  Any help would really be nice.  Thank you
