• 6.10 RC4 NFS access errors and connection failures

    Hello all
    I switched to Unraid version 6.10 last week because I had frequent problems with NFS (Linux Mint has NFS 4.0 but Unraid has a smaller version), this combination caused frequent problems, almost daily the accesses to the NFS shares were lost.

    Since the change I have less problems, but after larger file operations the access to the NFS drives of the Unraid server does not work anymore .

     The system log shows the following messages:

    You didn't answer the question about how you are mounting the NFS devices.  Fstab?

     

    You need to post a diagnostic when the issue comes up, not after a reboot.

    Sorry, I did not have time.
    The mounting is done with the FSTAB:

    #### NFS####

    Since the day before yesterday there was no connection failure.
    Is like at the dentist , when you are there , no pain.

    Use UD (Unassigned Devices Plugin) to mount remote NFS shares.  UD handles the remote shares properly.  It's hard for us to support fstab mounts because of all the specific settings and user misconfiguration.
