David, As far as I know, the only development ongoing related to shared root is in the = SSI Linux project. I believe that they have the goal of achieving it with multiple mechanisms: Via OpenGFS using shared storage. (This is working. I don't know what the = quality is.) Via Sistina's GFS using shared storage (I don't know if they still support = this or not.) Via GNDB using local storage (this has been at least temporarily dropped = due to lack of GNDB support). Via CFS using local storage (Cluster File System). The SSI team is doing = this themselves. And I think there has been discussion of using some kind of a modified NFS. So if in the below, you are offering to help in developing/supporting a shared = root solution you may want to investigate their project. I have copied this response to the SSI mailing list. For the pure NFS over GFS issue, you may also want to investigate Sistina's GFS = mailing list. Be aware the Sistina's GFS product is a commercial product. I = don't know what the source code availability is. Their mailing list is more = active than the OpenGFS one, and the source code was common to both projects as = of June 2001.

That means if we implement fh_to_dentry() call in GFS it will be safe for use with NFSd. If Sistina is able to do so, and OpenGFS is a continue of GPL version of the sistina GFS... are they pretty much the same?

NO. GFS looks to nfsd just like ext3 and all other "physical" filesystems. Perhaps there was some confusion. GNDB is a block device. > That means if we implement fh_to_dentry() call in GFS it > will be safe for use with NFSd.
