Hi list, as I know from the README in the source files OCFS2 does not support cluster aware flock. Our web developers have to use the php flock() function. There is a second method how php can handle locking - via the fnctl() function. Will this be supportet? I assume that OCFS2 supports the c-function open() mit O_CREATE as well as O_EXCL. Am I right?
