On Red Hat Enterprise Linux (RHEL) 6.6 the umount(8) command hangs if an application is watching for inodes events on a VxFS file system using inotify(7) APIs
Veritas have produced patches to resolve this issue, see the table below:
Previously, a fix was available in the form of a private hot fix (fs-rhel6_x86_64-6.2.0.001)
Note: The patches above for 6.0.5 and 6.1.1 are also contained in the combined patches sfha-rhel6.6_x86_64-220.127.116.11 and sfha-rhel6.6_x86_64-18.104.22.168, If installing SFHA for the first time, it may be more efficient to use these combined patches (or later).
Workaround (if no patch):
Abort the applications that are using inotify APIs (poll(2), select(2) and epoll(7)) before un-mounting the file system
