[Lustre-discuss] recreate metada - possible?

[Tom Woezel]

Hi all,

I have a bit of a problem here. I am currently running Lustre 1.6.7 on  
5 servers. 2 servers for MGS/MDT and 3 for OSDs. Behind the 2 MGS/MDT  
servers (failover setup) is a raidarray so that both machines can use  
the device. Now the partition table on the raiddevice got deleted and  
cannot be recovered. The OSTs are ok and the data on those should be  
fine.

Now here is my question is, it possible to create a new MGS and new  
MDTs and somehow connect the old OSTs to them? Is there a way to  
recreate the metadata with the data whis is held on the OSTs?

I'm deeply grateful for any help or hint on this issue.

Thanks in advance
