I want my main server to keep the files locally but write all of the changes to an NFS drive at the same time. My backup server should then be able to read the data from the NFS drive if the main server goes down. Here are my questions: Can I setup NFS with a union mount so that if the server writes to /var/mail to is written to a local copy that is accessed as /var/mail but is also written to the NFS server (transparently) as /var/mail? Can the NFS mount be write only? I want to read from the local copy but write to both the local copy and the NFS. I have not been able to find any docs on union mounts for FreeBSD. (BSD/OS had and option for this.) Is it even possible to do what I propose? Thanks in advance. -- Randy Smith Amigo.Net Systems Administrator 719-589-6100 ext. 4185 http://www.amigo.net/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
