* gfid: introduce uuid based handles for inodesAnand Avati2010-09-044-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gfid represents a gluter file id. This is a universally unique id assigned to a logical inode, independent of the inode numbers assigned by the various backend filesystems to that file/directory. The gfid of a file/directory will be the same on servers depending on the cluster translator in picture. The same gfid can be used as a handle across layers of various translators and across servers and clients. This was not the case previously as the cluster translators would pick the backend inode number from one of the servers and convert that into a logical inode number by performing some mathematical transforms. This new technique of addressing inodes also makes dynamic volume management have a more robust implementation as the file handles remain the same on all versions of the graphs, and allows for seamless NFS daemon restarts as well. This change makes way for server originating communication which was not possible earlier as the servers did not have any reliable way of addressing client side inodes at all. gfid solves this problem by preserving the same uuid as the handle on all the servers and across all clients Signed-off-by: Anand V.

* fuse: introduce pre-test micro-framework, check for execve-over-direct-IOCsaba Henk2010-09-023-11/+334
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The presence of some potential FUSE features in the actual kernel-side FUSE implementation we run on is not always straightforward. More precisely, it is straightforward only if there is a dedicated feature flag or protocol revision number. In the other cases we are left to clumsy and platform specific hacks which wire in 3rd-party software revision numbers into our source... at least, if we insist on sticking to (the otherwise venerable) KISS principle. However, here we go for another route, loosely inspired by the way autotools provide an abstraction layer for our build system over the gory details of platform specific build environments. At start time, we use a preliminary set of FUSE operations which overlay the standard ones such that apart from the "usual stuff", they also present some synthetic files to the FUSE client (kernel). Then we spawn some test programs which perform the needed tests on these synthetic files to evaulate the FUSE implementation in terms of the features in question. According to the result of the test programs, we set the respective parameters of the fuse xlator; when the testing phase is over, the FUSE operation set is replaced by the standard one. As of now, we use this approach to test whether execve(2) works with direct I/O. If yes, and if glusterfs is used with --enable-direct-io-mode, then we let direct I/O for files opened for reading; if no, then we restrict direct I/O only to writing files.
