The default behaviour is the same as on Solaris, but it can be modified. From the mount_nfs(8) manpage: By default, mount_nfs keeps retrying until the mount succeeds. This behaviour is intended for filesystems listed in fstab(5) that are criti= =AD cal to the boot process. For non-critical filesystems, the -b and -R flags provide mechanisms to prevent the boot process from hanging if the server is unavailable. If the server becomes unresponsive while an NFS filesystem is mounted, any new or outstanding file operations on that filesystem will hang unin= =AD terruptibly until the server comes back. To modify this default behaviour, see the -i and -s flags. --=20 <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
