nfs share with aufs - fsid option

  • Hi there,


    i have a "aufs" poolshare that ist without problems as smb share in the linux client.
    As nfs share it makes trouble.


    without the fsid=0 option the attempt to mount is possible, but i have no rights to access the folder
    syslog: Cannot export /export/multimedia-pool, possibly unsupported filesystem or fsid= required


    with the fsid=0 (recommended) option:
    mount.nfs4: mounting 192.168.1.4:/multimedia-pool failed, reason given by server: No such file or directory
    syslog: /export/multimedia-pool and /export have same filehandle for 192.168.1.1/24, using first


    can anyone help me please?


    greetings

    It should just be fsid (read the Info tab in the aufs plugin).

  • thank you!
    I try to unterstand knowledgebase article.
    There ist written:
    "An fsid can be set anywhere from 0 - 255. However, 0 has special meaning for NFS v4, so if you are using NFS v4, only use fsid=0 on the top (fake root) of the export hierarchy"
    I tought sardaukar is using nfs v4?! i mount with "mount -t ntfs4" so i have use fsid=0?! but the i can´t mount "No such file or directory"
    where is the bug?

    The way I interpret that is the *only* time you use fsid=0 is for exporting the root i.e. /export not /export/multimedia_pool. You can't do that with the OMV web interface, so you should never be using fsid=0.

  • therefore another fsid value i attempted like fsid=2 is functional,
    but i don´t understand the matter in reference with a aufs pooling.
    nfs v4 should export all shares unter root export?!
    The main is the success, thanks a lot!
    nice if someone give me someday the unterstanding to aufs and nfs4 export

    fsid is an nfs setting. I can't set nfs settings from the aufs plugin. This has to be done in the nfs plugin.
