Do not hardcode umount(8) path, emulate lazy umount

2014-10-03T15:01:29+00:00

1) Use a system-dependent macro for umount(8) location instead of
relying on $PATH  to find it, for security and portability sake.

2) Introduce gf_umount_lazy() to replace umount -l (-l for lazy) invocations,
which is only supported on Linux; On Linux behavior in unchanged. On other
systems, we fork an external process (umountd) that will take care of
periodically attempt to unmount, and optionally rmdir.

cli/glusterd: Added support for dispersed volumes

2014-07-11T17:34:24+00:00

Two new options have been added to the 'create' command of the cli
interface:

    disperse [] redundancy 

Both are optional. A dispersed volume is created by specifying, at
least, one of them. If 'disperse' is missing or it's present but
'' does not, the number of bricks enumerated in the command
line is taken as the disperse count.

If 'redundancy' is missing, the lowest optimal value is assumed. A
configuration is considered optimal (for most workloads) when the
disperse count - redundancy count is a power of 2. If the resulting
redundancy is 1, the volume is created normally, but if it's greater
than 1, a warning is shown to the user and he/she must answer yes/no
to continue volume creation. If there isn't any optimal value for
the given number of bricks, a warning is also shown and, if the user
accepts, a redundancy of 1 is used.

If 'redundancy' is specified and the resulting volume is not optimal,
another warning is shown to the user.

A distributed-disperse volume can be created using a number of bricks
multiple of the disperse count.

glusterd: Check mount_dir for own bricks only during start

During the start volume commit op brickinfo->mount_dir was being checked
for all bricks by glusterd. This could lead to failures starting the
volumes which were carried forward on upgrade.

Several volume operations, start, add-brick and replace-brick, expected
the presence of a bricks mount directory, which is required for the
snapshot feature. This should only be expected when snapshot is
supported in the cluster.

glusterd: Allow setting volume options by default based on op-version

2014-05-14T10:14:33+00:00

A new function glusterd_enable_default_options is introduced, which will
set some volume options on a volume based on op-version. This function
is called near the end of the volume create and will allow some options
to be enabled based on op-version on newly created volumes. This will
also be called during volume reset, to reset the options to their
default values if they had changed.
