Hi everyone, In our lustre setup, we have a few hundred native linux clients and a few samba gateways sharing the filesystem over CIFS to about a hundred windows clients. When the linux clients are idle, we can drive up to 400-500MB/s per samba gateway. When the linux clients are crushing the filesystem, we only get about 100MB/s per gateway. This makes sense, because in this case our storage backend is the bottleneck. We are looking for a way to give a bigger share of the available bandwidth to the samba gateways. We played with max_rpcs_in_flight but that helped only so much. Here is an idea we had:. mount the lustre filesystem multiple times on the samba gateways and share multiple SMB path out. We would then use some kind of load balancing between all the UNC paths. We tried it on a small lustre and it is possible to do it. We are a little worried that some race condition shows up when we do it on a larger scale. How good or bad is that idea? Anybody else found a solution for this particular problem (other than add more gateways)? Thanks, Julien IMPORTANT: The information contained in this email and/or its attachments is confidential.
