I believe that Lustre is very suitable for what you describe, but we should make sure by discussing in more detail your precise requirements. Best-- -Phil
Hello! We will design a new storage architecture for our webhosting service and lustre is one solution we are considering to evaluate. Today have we about 17Tb divided on 40 filers and clients use NFS to access data. So we are talking about many, many million of files (>400000000) and output bandwidth is 300-500Mbits. So would lustre be suitable for this kind of environment? Thx /J -- In disk space, nobody can hear your files scream.
Ok, that sounds good. It''s a quite big project to migrate our current storage solution to a new one. So we will probably consult your "Lustre Evaluation Service" (if we decide us for lustre). But we still have some (newbie) questions for you. 1, We have filesystem quota today (all members homedir). So how is that working in lustre? 2, And if a filesystem get corrupted how do you fix that?

I expect to include this feature in a production release in 2005, but the precise date or release has not been decided.> 2, And if a filesystem get corrupted how do you fix that?If a file system gets corrupted (we have so far only seen this as a result of failures of the back-end storage, like a RAID-set failure), the Lustre fsck tool can re-synchronize the various file systems. It is built as an extension to e2fsck, so it also corrects the internal ext3 errors at the same time. Thanks-- -Phil
