[Lustre-discuss] how to recreate an OST?

[Bernd Schubert]

Hello,

lets assume there had been a severe hardware failure and an entire OST was 
lost. Now I simply want to recreate this OST - I run mkfs.lustre and 
tunefs.lustre --index={old index of the lost ost}.
Now on mounting this OST mount.lustre and the MGS complain this index is 
already in use. Nice, but how can I convince it the action I try to do is  
correct? tunefs.lustre --writeconf /dev/mgsdevice doesn't help.

Any ideas?

Thanks,
Bernd


PS: No real data lost, I'm just to lazy to re-create the entire Lustre 
filesystem.
