I am trying to set up a fail safe system. (Ok, a not-quite-as-likely-to-fail
system)
Ideally I have two MX records, one pointing to foo, and one pointing to bar.
The actual mail spool is on zork. zork nfs exports it's spool to
foo, bar, and a couple labs of workstations.
I currently use procmail to do the the final transport to the spool
directory.
Now if either foo or bar fails, the other box picks up the load.
But if zork is down, then foo and bar hang, as they try to do nfs
reads of the user's home directories.
Is there any elegant way of dealing with this?
I saw the reference to require_files doing a stat() on the directory
of the file. But this is not obviously of help, since the user
directories are two levels removed from the mount point.
(/u/vega1 is the exported and mounted file system. A users directory
is /u/vega1/visitors/juser)
And doesn't the stat() call hang anyway?
