+ + + pNFS Server Plan B + + + + + Rick + Macklem + + rmacklem@FreeBSD.org + + + + + Instructions for Testing + + + +

A pNFS server allows an NFS service to be spread over + multiple servers, separating the MetaData operations from the + Data operations (Read/Write). This project will add the + capability of using &os; systems to create a pNFS service + consisting of a single MetaData Server, plus a set of Data + Servers. The Data Servers can be mirrored, so that redundant + copies of the file data are maintained.

+ +

The support for non-mirrored Data Servers is now believed + to be complete. Support for mirrored Data Servers using the + Flexible File Layout, which will soon be published as an RFC, + is implemented. However, there is still significant work to + be done, since the current implementation of mirrored Data + Servers does not handle failed Data Servers or their + resilvering/recovery. It is hoped that support for + failure/recovery of Data Servers will be implemented in the + next six months.

+ +

The patched &os; sources may now be accessed for testing + via either Subversion or download of a gzipped tarball. + They consist of a patched kernel plus nfsd daemon and can be + used on any &os; 11 or later system. The installation + procedure is covered in the linked document.

+ + + + Testing by others will be needed, now that the + implementation is available. + + Implementation and testing of mirror failure/recovery. + +
