Error description

  • afmParallelMounts option can be enabled at the fileset
    level which creates parallel mounts to the different NFS
    servers. Some dentries created as part of the parallel
    mounts may not connect to the filesystem root dentry
    and causes a VFS busy inodes issue when the fileset
    is stopped or unlinked.
    

Local fix

  • Disable afmParallelMounts.
