I opened this ticket [ https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=201155] a week ago, but haven't heard since. I thought to discuss it here. Here's a paste of the bug for convenience. Thanks all! My Setup is: * A FreeBSD 10.1 with ZFS exporting NFS4 to a Linux server * That Linux server is a NIS master for the FreeBSD box The issue is: * Upon power failure .. Both servers starting fresh * FreeBSD boots faster (grin) * FreeBSD doesn't find NIS master and bombards logs with hundreds of thousands of messages!! like Jun 27 13:47:53 nas /usr/sbin/ypbind[827]: NIS server [192.168.10.254] for domain "SIVISION" not responding Jun 27 13:48:24 nas last message repeated 51704 times Jun 27 13:49:26 nas last message repeated 104381 times * In this state, FreeBSD does not allow any other machine to NFS4 mount its shares. This includes the NIS master Linux box * Linux boot hangs waiting for the NFS share to allow it to mount it * We are in a deadlock. Linux waiting for the NFS share to mount, while FreeBSD is waiting for the NIS server on Linux to start
