I am running 5.0-rc8a.  It's been very stable but the last couple of days, I come home to find the server unaccessible.  Neither menu nor unmenu is reachable on the browser.  In Finder on my Mac, I do not see the shares with aFP or SMB.  Only thing I could do is force a reboot.  After reboot, it seems ok, even parity check is fine but hours later, same thing happens again.

 

I've attached full syslog from last reboot - many red errors.  I see errors on sdb drive which is my cache drive.

syslog-2013-12-03.txt

Post a SMART report.

In running this command - smartctl  -a  -d  ata  /dev/sda | todos >/boot/smart.txt

 

I don't have an sdb in /dev ?  Now I notice in unmenu that my sdb (cache) drive says RAW and has the NEW icon.  It's been awhile since I installed this system.  Do I do a preclear again?

Connect a keyboard and screen to the server and copy the syslog to the flash after it stops responding.

Since I got those IO errors on the syslog - the cache drive (sdb) has not been in the protected array and the system is stable.

 

In the unRaid menu, it says sdb is unassigned but when I try to precelar it, I get this error message:

 

Sorry: /dev/sdb does not exist as a block device

Clearing will NOT be performed

 

Not sure what I can do to get this drive back as a cache drive.  It does not show up in /dev directory. Help !

 

Reboot.
