The GFS interfacehas been accomplished with modifications to boththe mount table,.PN sys/mount.hand to the inode, which under the GFS interface implementationis referred to as the gnode.  The gnode is defined in the.PN sys/gnode.hand .PN sys/gnode_common.h ..PPThe GFS interface allows superusers to.PN mount and .PN umountfile systems on local and remote machines.Changes to the.PN /etc/fstabfile allow any type of mount to occur automatically at boot time in thefiles .PN /etc/rcand .PN /etc/rc.boot .Other than mounting and unmounting file systems, users should not seeany difference in the local file system..PPThe GFS interface requires two system calls: .MS getmnt 2 and .MS getdirentries 2 .The .PN getmntsystem call handles generic mounted file system data.The .PN getdirentries system call handles generic directory entries from any file system..SH See Alsogetdirentries(2), getmnt(2), mount(2), fstab(5), nfs(5nfs), ufs(5),fsck(8), mount(8)
