Hi there, I'm planning to run FreeBSD as a lab file server. I'm aware of the NFS server write delay problem, which slows down writes from the client. I know about the "insecure option" on the client, which I dont intend to use. On Sun Servers you can add a small battery-backed memory to the system where NFS writes end up in first, before being written to disk. This looks like an elegant solution at a first glance, however, the size of memory is fairly limited. I have been studying FreeBSD sources to find a hint for a similiar solution, but it doesn't seem to be there. There are no hooks. Does anyone know of a prestoserve implementation for FreeBSD machines, as a PCI board, perhaps ? If not, what solutions do people use to speed up NFS writes ? Do you guys run your NFS file server in "insecure" mode and have a UPS for the case of a power failure ? What about system crashes ? Thanks for enlightening me. Regards, Joerg -- Joerg B.
