Help! Shares Missing and Array showing as new after Power Outage

Featured Replies

Help!

 

I had a power outage last night and did not know about it.  The only reason I think it was an outage is because I had to reset my router and modem and my cable box tvguide was blank this morning.

 

Anyway,  I was going to transferred some new files from my pc to my unraid tower and my comp was showing the tower as not being in my network.  So I send my firefox browser to tower:8080 and it times out.  So I turn on the unraid monitor and powerdown.  I restart the unraid tower and login.  when i got to the tower:8080 site on my pc, it shows

Array Status  NEW_ARRAY, unRAID ARRAY is STOPPED 3 disks in array.    PARITY NOT VALID: DISK_NEW

Array Disk Status

Status Disk Mounted Device Model/Serial Temp Reads Writes Errors Size Used %Used Free

DISK_NEW new disk /dev/sda _ 32°C 165 0

DISK_NEW new disk /dev/sdb _ 32°C 171 0

DISK_NEW new disk /dev/sdc _ 32°C 171 0

Total: 0.00K 0.00K 0.00K

 

I've tried powerdown and turning on the unraid tower but it still shows as being a new array.  I also updated my flash drive to unRAID 4.5.6 and I'm still getting the same error.

 

Please Help!

These two lines in your syslog tell it all

Aug  8 15:24:37 Tower kernel: md: could not read superblock from /boot/config/super.dat
Aug  8 15:24:37 Tower kernel: md: initializing superblock

Your flash drive suffered some corruption.  The super.dat file was un-readable.

 

I'd move the flash drive to your PC, and run a scandisk/checkdisk on it  (right click on the icon for the flash drive and check it for errors)

 

Then, move it back to the unRAID server and reboot.

The array will wait for you before it will start.  When you do start it, it will begin a full parity calculation.  Let it complete.

Thanks Joe for responding.

 

I tried that, checking for errors on my pc. It found some and "fixed" it.  I safely ejected my flash drive and put it on my tower, started it up and logged in.  Went to tower:8080, and I still have all 3 hard drives showing as new.

 

Do I have a bad flash?  Should I get another? Should I try the check error again?

Thanks Joe for responding.

Good that if fixed the errors.

 

Now you can "Start" the array, let it calculate parity, and you should be back to normal.  I'll bet the flash drive was not mounted as read-only this time.  Remember, it created a new config/super.dat last time when it was unable to read the original one, so now you need to let it re-calc parity  (odds are writing exactly the same contents as are on the disk right now)

 

Press "Start", go to sleep...  in the morning, it should be done.
