Nicolas, from what I understood you want to write the file once and have it written twice (on two different OSS) servers. Lustre calls it as 'Multi-server file RAID-1'. According with Lustre's roadmap ( http://www.clusterfs.com/lustre-roadmap-2006.pdf) this feature I'll be present at the 1.8 version of Lustre.
Nowadays you already use the best high availability resource I know for Lustre (every OSS has it's mirror). Best regards, Daniel Colchete On 12/29/06, Nicolas Bogucki <[EMAIL PROTECTED]> wrote:
Hi all, I am currently testing lustre to check if it can possibly replace my NFS mounts... My files are spread on multiple NFS server so that, if I lose 1 NFS server I only use access to data located on this server which is solved with data written twice. stable enough but not very scalable, isn't it?... Of cours, I expect a lot more from lustre scalability... I understood that I am able to... ... write to one file system which is hosted on multiple servers ... write to one file system which is hosted by one server and mirror on a second one I'd like to mix both with some kind of mirror for each of my server hosting a peace of my lustre filesystem. This way, I would be very scalable and still fault tolerant. Is this possible? Thanks for your help! Regards, Nicolas.
