Re: EINTR error in SunOS

From the Linux 'nfs' man page:

intr If an NFS file operation has a major timeout and it is
hard mounted, then allow signals to interupt the file
operation and cause it to return EINTR to the calling
program. The default is to not allow file operations to
be interrupted.

Solaris 'mount_nfs' man page

intr | nointr
Allow (do not allow) keyboard interrupts to kill
a process that is hung while waiting for a
response on a hard-mounted file system. The
default is intr, which makes it possible for
clients to interrupt applications that may be
waiting for a remote mount.

The Solaris and Linux defaults seem to be the opposite of each other.

So I think we are saying the same thing.

You can get EINTR with hard+intr mounts.

I am not sure what you get with soft mounts on a timeout.
