    Stop broken NFS mounts from locking a directory in solaris 11.3


      Data from my nfs server:

      zfs set share=name=opt_media,path=/opt/media,prot=nfs,sec=sys,root=iphostclent,public,rw=* rpool/media


      Data from my nfs client:

      mount -F nfs -o bg,soft,retry=5,timeo=5 iphostserver:/opt/media /opt/media


      I use options:






      more info:


      nfsstat -m

      /opt/media from iphostserver:/opt/media

      Flags:         vers=4,proto=tcp,sec=sys,soft,printed,intr,link,symlink,acl,rsize=1048576,wsize=1048576,retrans=5,timeo=5

      Attr cache:    acregmin=3,acregmax=60,acdirmin=30,acdirmax=60


      but, if I turn off my nfs server, in my nfs client the /opt/media/ directory is blocked.




      The problem are the applications, for example df -h it freezes, or an app that depends on the /opt/media/ directory, also it freezes, and this is because the nfs client is trying to reconnect infinitely, therefore the parameters bg, soft, retry = 5, timeo = 5 to stop retry, but it does not work.
