Description Christian Weisgerber freebsd_committer freebsd_triage 2014-02-09 18:50:00 UTC 
By default, mounting an NFS filesystem from a server that has an
AAAA record but doesn't support RPC/NFS over IPv6 causes mount(8)
to hang.  This can be avoided by specifying the "noinet6" mount
option.

However, even with "noinet6" umount(8) will hang when unmounting
the filesystem.  If you ^C umount, the filesystem has successfully
been unmounted.

A workaround is to specify the server by its IPv4 address rather
than hostname.
