1.) mkfs.lustre ... (many parameters) /dev/device
2.) tunefs.lustre --index={failed_index} /dev/device

3.) mount -t lustre /dev/device /mnt/somewhere

--> failed: Address already in use

4.) Wrote mail and got your answer

3.) mkfs.lustre --index --writeconf ... (many paramters) /dev/device
4.) mount -t lustre /dev/device /mnt/somewhere
 
--> failed again: Address already in use

Now I mounted the mgs as ldiskfs, and in CONFIGS/ there is no file for the 
missing ost. 
But now I just found the reason - the failed OST was still activated on the 
clients. After deleting CONFIGS/{fsname}-client and remounting as type lustre 
again, registering the failed ost works!
I guess one shouldn't do it this way if one still has important data on the 
filesystem ;) 


Thanks a lot for your help,
Bernd
