Bug 13642

Summary: mfs incompatible with nfs
Product: Base System Reporter: mdudley <mdudley>
Component: i386Assignee: freebsd-bugs (Nobody) <bugs>
Status: Closed FIXED    
Severity: Affects Only Me    
Priority: Normal    
Version: Unspecified   
Hardware: Any   
OS: Any   

Description mdudley 1999-09-08 21:10:00 UTC 
After succesfully installing an MFS (memory file sytem or ram disk) on
a server I then proceeded to mount it through NFS. It acts like a
successfull nfs mount but when trying to acces it gives me the
following error:
"Input/output error"

Fix: 

Unknown, badly needed.
How-To-Repeat: Totally repeatable, no way to avoid I can find.

From sys/i386/conf/LINT

# Allows MFS filesystems to be exported via nfs
options         EXPORTMFS

State Changed
From-To: open->closed

User has observed the expected behavior. 

Use: 
options         EXPORTMFS 
in kernel config file and recompile to allow MFS filesystems 
to be exported via NFS.
