TeraStation Pro TS-RHTGH/R5 Bizarre Behavior

[swade2569]

   

I posted in another thread, but this issue has taken a rather bizarre turn so I thought it deserved it's own thread.

 

Yesterday I came in to work to find that the TeraStation has a red error light on the console and says "E14 Cannot mount RAID Array1".

 

I check the drives I have mapped and I can access that array just fine.  I browse a few folders, open a couple files, everything seems fine.

 

After doing some searching for a condition like this, I find no results (which indicate the error, yet no problem), I see nothing in the system or file logs indicating a problem, I figure I should restart.  

 

I shut down the TeraStation and restart it.  No error light and things still look fine.

 

This morning, same thing.  Red error light, same error, yet I can still access everything just fine.  I try to initiate a shutdown, but I can't get past the login screen on the browser interface.  This seems odd.  I try a different computer; same problem.

 

I hold the power button on the TeraStation until it says it's shutting down.  I power it back up.  It takes a little longer then I get "E04 Can't Load KRNL".  Just to be sure, I power it off and restart, but I get the same error.  

 

I download all the stuff and a handy instruction guide for fixing via TFTP (http://forums.buffalotech.com/buffalo/board/message?board.id=0101&message.id=4820&query.id=957#M4820).  I attempt to boot to EM mode.  It says it's starting to boot EM mode.  I turn my back to prep the workstation's IP address and everything and get the TFTP Boot running.  

 

I turn back around, the NAS is up and running with it's normal IP and there are no indications on the display that it's in EM mode.  I check the network and once again all the shares and data are accessible.

 

What Gives?

That IS bizarre. Force update the firmware, after checking Delete User Config in the Debug menu of the Updater. If this behavior continues, you may have a failing drive or drive controller.

Same thing AGAIN this morning.  I can use the browser to see the system status.  System Log is clear of errors. 

 

I'm just going to let it ride for a week.  It's being actively backed up so I'm not worried about losing data.  If it continues into next week I will try the force update and see if that helps.

 

This is a little preposterous though.  This NAS is intended to be my redundancy; now I have to create redundancy for it as well.  Good thing drive space is still cheap.

RAID is no substitute for a good backup plan... RAID does indeed offer redundancy, but only in the case of a single failure mode: a hard drive failure. RAID cannot protect against data corruption, accidental deletion, other hardware failure, or Acts of God.
