* volgen: reimplement volgenCsaba Henk2010-10-023-62/+51
| | | | | | | | | | | | | | | | | Generating a volfile occurs in two steps: - Build a graph (ie, glusterfs_graph_t instance) by graph manipulation primitives - Write out the graph to a file by the the graph printing API. Graph builder routines can optionally make use of a "modifier dict", which can contain overrides wrt. volume options. This can be used for a "dry-run" graph generation.

* libglusterfs: handle failure properly in gf_system()Csaba Henk2010-09-211-1/+6
| | | | | | | | | | | | | | | | - Child must be terminated if execve(2) fails, otherwise it will deadlock parent - Status, as of given by waitpid(2), is aggregated data, should not be returned as is. In fact, there is not much point in threading up the exitvalue: callers usually return gf_system result as is, and according to glusterfs conventions, they should return -1 on failure. Therefore now we check only for success/fail, and return 0/-1.

* gfid: introduce uuid based handles for inodesAnand Avati2010-09-043-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
