Hi all,
The name of the feature changed to 'Barrier' in order to avoid
the confusion between the 'Quiesce' translator.
A much detailed version of the document is updated here http://www.gluster.org/community/documentation/index.php/Features/Server-side_Barrier_feature.
All comments/suggestions/critics on both document and the
feature is welcome.
Thanks

Hi all,
Volume snapshot feature snapshots a volume by snapshotting
individual bricks, that are available, using the lvm-snapshot
technology. As part of using lvm-snapshot, the design requires
bricks to be free from modifications. Snapshot feature needs a
mechanism in GlusterFS, where file operations such as write,
mkdir, mkdnod, unlink, truncate etc, that modify the underlying
file system, are ‘quiesced’ until the snapshot of the brick is
taken.
This mechanism should have the following properties:
• Allow file operations that do not modify the underlying file
system.
• Should keep the ‘quiescing’ transparent to the applications.
This is where the server-side quiescing of file operations comes
into picture. So the feature page[1] for Server side Quiesce is
created in the gluster.org. Please review the document &
design of the feature and provide your
comments/suggestions/critics.
