To be more complete, we don't like how locks are handled by any of previously mentioned products. Ideally, there sould be a Distribuited Lock Manager (DLM), among all servers, and all layered products, both FS and NFS server, should use that DLM in order to manage/share locks. Is there any idea to develop a DLM on FreeBSD, to be integrated in kernel? Tonino Zinevich Denis ha scritto: > The same issue for me. I have SAN connected to 4 servers.
