At the university we have are importing over 40 lustre filesystems. I was wondering if anyone is using autofs to mount up the lustre clients and if its recommended? TIA
How is your mapping set up? Did you do anything special? I have done many NFS maps but is there anything different with Lustre?

One of the benefits of Lustre is that you can have a single filesystem across many servers (unlike NFS) and the value of the single aggregate filesystem is more than the sum of its parts. The bandwidth available to the clients is higher, the space can be shared more effectively, etc. Cheers, Andreas -- Andreas Dilger Sr. Staff Engineer, Lustre Group Sun Microsystems of Canada, Inc.

You can also use quotas to limit space usage by particular users. Cheers, Andreas -- Andreas Dilger Sr. Staff Engineer, Lustre Group Sun Microsystems of Canada, Inc.
