Hi Larry, thank you for your answer, but I do not have the chance to use infiniband. This description also starts with formatting the fs. I don't want to format the already in user node. I would like to extend it online. Is it possible to achieve full sync of the data of the two nodes (the one existing already, and the second is the new that is on the new server about to be attached) The old node has 50% of its capacity uploaded, the new node is completely empty.
So the question is, how do I add a failnode to an online system and how do I manage to get the data to be in synchron. Hope someone can help thank you, Lucius ----- Eredeti üzenet ----- From: Larry Sent: Tuesday, March 01, 2011 6:25 AM To: Lucius Cc: lustre-discuss@lists.lustre.org Subject: Re: [Lustre-discuss] OST problem Hi Lucius, lustre manual chapter 15 tells you how to do it On Tue, Mar 1, 2011 at 1:05 PM, Lucius <lucius...@hotmail.com> wrote: > Hello everyone, > > I would like to extend a OSS, which is still in current use.
