I'm not using a block-level distributed filesystem like GFS or OCFS. GlusterFS is a file-level protocol, more like NFS, and as far as I know there is no inherent locking between clients. > And when the volume stretches across several machines, > even though the reading might be done from the local disk, the locking has to > be synchronized across all brick-machines. Another limit. Which locking is that? Can you point me to any documentation which says so, or the part of the source code which implements it? Why, when I simply read a file, would a lock need to be created anywhere?
