TeraStationPro: System Error E04 - no Superblock in /boot

[BerndHennig]

   

G'Day,

 

 

after a power failure the TeraStation Pro we use "boots" into

System Error E04

Can't Load Krnl

 

We tried everything from the list her:

 

- tftp, conncted to a M$ PC: We never see any bit coming from the TSPro,

  so tftp didn't work

- EM boots and boots and boots and boots..... (neverending story)

 

So HOW can we bring back the TeraStationPro into a - let's say - new status (we have a backup on a USB HD connected to the TSPro and pray (!) that this copy is readable later....)

 

HELP !

Did you try booting the device with each HDD individually (using the EM procedure)?

G'Day,

 

with only disk 1 "in" the TSPro starts with the EM button pressed in the EM mode, ip 192.168.11.150 and no array info.

 

What to do next to

 

a.) bring back the OLD system with the data

 

or

 

b.) bring back a NEW system and later copy the data from the external USB drive

 

 

I managed to login, looks like the boot disk /dev/sda1 is not longer bootable (sorry, I'm not a Linux expert, I work more with Solaris)

 

root@TS-HTGL-EM66E:~# fdisk -l

 

Disk /dev/sda: 500.1 GB, 500107862016 bytes

255 heads, 63 sectors/track, 60801 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

 

   Device Boot      Start         End      Blocks   Id  System

/dev/sda1               1          37      297171   83  Linux

/dev/sda2              38          99      498015   83  Linux

/dev/sda4             100       60801   487588815    5  Extended

/dev/sda5             100         116      136521   82  Linux swap

/dev/sda6             117       60784   487315678+  83  Linux

 

 

So the solution should be (?) to make /dev/sda1 bootable again ?

 

 

Cu & Tnx for help
