    Reason: mount: mounting 172.17.17.82:/media/Images/ on /images failed: Permission denied

    I have migrated fog from a physical server to a VM and have moved image storage from said physical server to a NAS folder which is mounted at /Images on the fog VM. The storage location is entered in the default storage node attributes. The node comes up as expected in the dashboard, and old captured images are seen in dashboard as well. Based on the message and having read some of the similar error messages, I suspect permission issues, but I’m not sure how to address them.

    I’m running fog 1.5.9

    [sudo] password for netadmin:
    chown: invalid user: ‘fog’
    
    

    The image folder is mounted using smb credentials of a user “fog” created on the NAS, and I can create files on the mount from fog based on those credentials. I’ll happily change this to clear any ambiguity, but I’m chasing my tail I think.
    Where am I?

      @geardog said in Could not mount images folder (/bin/fog.download):

      //172.17.17.201/Images 7.3T 4.4T 3.0T 60% /media/Images

      I am not sure if it’s possible to export a SMB mounted share via NFS.

      chown: invalid user: ‘fog’

      FOG used this username for a while but we switched to fogproject some time ago.

      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

        I made the image folder public, and it didn’t change anything.
        It’s actually mounted in fstab using cifs utils, and the NAS shows it has NFS support. I’ll look into a different way to mount it.

          So I’ve edited fstab to mount the images folder (on the NAS) with NFS, it shows up in dashboard, and I can write to it from fog terminal. I’m still, however, getting the same error upon trying to deploy an image to the box. Thoughts?

          I’m stumped again.

            @geardog said in Could not mount images folder (/bin/fog.download):

            So I’ve edited fstab to mount the images folder (on the NAS) with NFS,

            Sorry, should have said that earlier but you definitely can’t re-export an NFS mounted share via NFS again. While I am not exactly sure NFS on top of SMB/CIFS works (probably not) I am sure NFS on top of NFS does not work.

            Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

              Wow, so is my only known option for external storage making the NAS behave as a storage node? It has a flaky proprietary OS/GUI that has warning everywhere. “You will brick me if…”
