Hi Mark,

I would try this, but I don't know how... Is this a setting in the MVME2100-settings or in the dhcpd.conf of my TFTP/DHCP/NFS-Server?

Hi Michael,

Earlier in your startup I see this:

***** Initializing NFS *****

Mount 192.168.99.1:/soft on /soft

Can you try manually mounting /autosave at that point, and not rely on the autosave module to handle the mount for you?

Mark

Subject: autosave 5-10-1 on RTEMS-4.10.2, mount failed

Hi all,

I'm setting up an IOC, BASE-3.15.7 and autosave 5-10-1, on an Motorola board MVME-2100 using RTEMS-4.10.2.

The comand save_restoreSet_NFSHost fails on it with mount failed: Invalid argument . But my IOC is using nfs to mount it's "st.cmd" file, so I don't know why it is not seeing the autosave folder, that is also exported via NFS.

Here is my IOC Start-up:

This is how my dhcpd.conf for the MVME-2100 looks like (it is OpenSuse Leap 15.1):

   group {

    use-host-decl-names on;

    always-reply-rfc1048 on;

    server-name bam01;

    host vmecpu-20 {

      option host-name iocRtems;

      option script-name "/soft/epics/IOC/iocRtems/iocBoot/iocRtems/st.cmd";

      hardware ethernet 00:01:af:15:ad:97;

      fixed-address 192.168.99.250;

      filename "epics/iocRtems/iocRtems.boot";

      next-server 192.168.99.1;

    }

And this is the exports file-entry for my autosave folder:

/autosave          172.17.8.0/24(rw,no_subtree_check) 192.168.99.0/24(rw,no_subtree_check)

The command save_restoreSet_NFSHost("nfsioc","192.168.99.1") is using the CNAME-Record "nfsioc" which is just an alias for my NFS-Server.

If I set it to the real name of my NFS-Server ("bam01"), it results in the same error: mount failed: Invalid argument

So what argument am I missing? Does anyone know?
