Hello All, I have read some papers about lustre and now I am dipping into the source code. I have some questions about lustre. Lustre is good at fault tolerant for fail over(in the manul''s term), but not refer to fail out failure, for example when the OST is fail stop or the medium is damaged. GPFS has supportted quorum and Google File System used three replicas for data availability, So I think Lustre should also resolve this problem. It is important for storage service. I want to ask if lustre Realy has mechanism to resolve this problem or some future plans to solve it? I would be appreciated for any reply! Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://mail.clusterfs.com/pipermail/lustre-discuss/attachments/20070917/3cb5fe72/attachment.html
