Lustre discuss - Apr 2008 - Clients is not accessible when OSS/OST server is down

Hi,  everyone.

When OSS/OST server is down. Client server is not accesible.
I can not login by any method ( ssh, telnet ).
HA is not available over OSS/OST server yet.

Is there any lustre mount option to prevent this situation?
Any help would be greatly appreciated.

Regards,
