Re: fuse mount in fstab

    Hi

    
    I have tested a bit this with different ceph-fuse versions and linux
    distros and it seems a mount issue in CentOS7. The problem is that
    mount tries to find first the <param>=<value> from fstab
    fs_spec field into the blkid block device attributes and of course
    this flag is not there and you always get an error like this:

    
    mount: can't find <param>=<value>

    
    and stops here, the mount values are never parsed by
    /sbin/mount.fuse.ceph helper...

    
    The only workaround that I found without change mount version is to
    change the "spurious" = by another special character like a colon
    for example:

    
    id:admin  /mnt/ceph fuse.ceph defaults 0 0

    
    but you also have to change /sbin/mount.fuse.ceph parser:

    
    ...

    # convert device string to options

    fs_spec=`echo $1 | sed 's/:/=/g'`

    cephargs='--'`echo $fs_spec | sed 's/,/ --/g'`

    ...

    
    but this is a bit annoying...

    
    someone else has found the same mount fuse issue in RHEL7 or CentOS?
    

    Cheers

    Alvaro

    Hmm, it
      looks like a version issue..
      

      I am testing with these versions on centos7:
      

       ~]# mount -V
      

      mount from util-linux 2.23.2 (libmount 2.23.0: selinux, debug,
      assert)
      

       ~]# ceph-fuse -v
      

      ceph version 0.94.1 (e4bfad3a3c51054df7e537a724c8d0bf9be972ff)
      

      This do not work..
      

      On my fedora box, with these versions from repo:
      

      # mount -V
      

      mount from util-linux 2.24.2 (libmount 2.24.0: selinux, debug,
      assert)
      

      # ceph-fuse -v
      

      ceph version 0.80.9 (b5a67f0e1d15385bc0d60a6da6e7fc810bde6047)
      

      this works..
      

      Which versions are you running?
      

      And does someone knows from which versions , or which version
      combinations do work?
      

      Thanks a lot!

      Hello Kenneth,
        

        I have a working ceph fuse in fstab. Only difference I see it
        that I
        

        don't use "conf", your configuration file is at the default path
        

        anyway.
        

      I tried it with and without conf, but it always complains about id
      

        id=recette-files-rw,client_mountpoint=/recette-files/files
        

          /mnt/wimi/ceph-files  fuse.ceph noatime,_netdev 0 0
