fuse: create a new fd during fd-migration.

2012-10-02T21:18:14+00:00

Migration of fd to new graph involves creation of a new fd
to be used only for calls sent in that graph.

Earlier approach of using same fd across all graphs, with the
associated inode always guaranteed to be the one valid in
currently active graph, had issues because of the broken
immutability of the association of fd with an inode
(for the life of fd).

With this patch, there will be a basefd, which the kernel will be
aware of. This basefd, contains a mapping of an fd which is valid
in currently active graph.

mount/fuse: readdir() should return 32-bit inodes when 'enable-ino32' is used

2012-09-18T13:54:59+00:00

The glusterfs mount option 'enable-ino32' does not change the behaviour
of readdir(). fuse_readdir_cbk() uses entry->d_ino directly, and this
was missed in commit c13823bd16b26bc471d3efb15f63b76fbfdf0309.

By adding the function gf_fuse_fill_dirent(), the fuse_dirent structure
is filled in a similar way as the fuse_attr structure. This helper uses
the same function to squash the 64-bit inode in a 32-bit attribute.

fuse-bridge: Pass unknown option down to fuse

2012-09-12T21:39:06+00:00

In Linux, certain "filesystem-specific" options (passed in string form in last
argument to mount(2)), such as "rootcontext" or "context" are in fact common to
all filesystems, including fuse. We should pass them down to the actual
mount(2) call untouched.

This is achieved by adding "fuse-mountopts" option to mount/fuse translator and
adjusting the mount helper to propagate it with unrecognized options as they
are encountered.

mount/fuse: add mount-option "enable-ino32" for the native client

2012-09-07T01:32:26+00:00

By default the GlusterFS-native client uses 64-bit inodes. Some 32-bit
applications can not handle these correctly. Introduce a client-side
mount option "enable-ino32" which causes the FUSE-client to squash the
64-bit inodes into a 32-bit value.

mount/fuse: ignore any erros that might've happened while resolving entry in resolver.

2012-08-03T08:13:36+00:00

One error we hit was absence of gfid on backend. While the lookup
code-path generates a new uuid and sets it on file, resolver code
doesn't do that. Since, functionally (atleast after resolving parent
inode, we would be resolving the path in new-graph) both resolver
and lookup does same work, it would be no harm in ignoring errors
during resolving the entry. This would help us to continue with
the _extra_ work (like healing gfid as of now) in fuse_lookup_resume.

fuse-bridge: expose negative entry caching of FUSE

2012-07-19T16:05:30+00:00

Fuse kernel module supports caching negative entries, enabled
by specifying a timeout while returning ENOENT to lookup. This
patch enables the functionality to be enabled with the command
line.

Also fixed a typo bug in mount.glusterfs.in.
