Function Documentation

int gfs2_freeze_fs ( struct gfs2_sbd * sdp )

gfs2_freeze_fs - freezes the file system : the file system

This function flushes data and meta data for all machines by acquiring the transaction log exclusively. All journals are ensured to be in a clean state as well.

Returns: errno
