NFS Speedscript?

    • NFS Speedscript?

      Hallo,

      ich habe im ihad Forum folgendes script gefunden, welches auch auf der DM funktionieren soll.
      NFS Speedscript

      NFS Speedscript:

      Shell-Script

      1. #!/bin/sh
      2. # IP of your NFS server
      3. serverip=192.168.69.70
      4. # exported directory on your NFS server
      5. exportdir=filme
      6. # mount point on dbox
      7. dboxmountpoint="/var/mnt/nfs"
      8. # filesize to transfer in MBytes.
      9. # At least 8 MByte. Good values are 32 or 64 MByte.
      10. # Try 128 to be more accurate (takes much longer!)
      11. filesize=64
      12. # block sizes to test in KBytes, possible values are 1 2 4 8 16 32.
      13. # values have to be separated with spaces. See examples below.
      14. # blocksizelist="4 8 32"
      15. # blocksizelist="16"
      16. blocksizelist="4 8 16 32"
      17. # wether to enable synchronous reading, writing. Possible values are "yes"
      18. # or no. Normally synchronous reading or writing should be slower than
      19. # asynchronous, so to save some time most people would say "no" here.

      Mein NAS ist über das Mountplugin einbezogen, aber wenn ich das mit der folgenden Config auf meiner DM aufrufe ...

      Shell-Script

      1. #!/bin/sh
      2. # IP of your NFS server
      3. serverip=192.168.178.88
      4. # exported directory on your NFS server
      5. exportdir=/dreambox
      6. # mount point on dbox
      7. dboxmountpoint="/hdd/NAS"
      8. # filesize to transfer in MBytes.
      9. # At least 8 MByte. Good values are 32 or 64 MByte.
      10. # Try 128 to be more accurate (takes much longer!)
      11. filesize=64
      12. # block sizes to test in KBytes, possible values are 1 2 4 8 16 32.
      13. # values have to be separated with spaces. See examples below.
      14. # blocksizelist="4 8 32"
      15. # blocksizelist="16"

      17. # wether to enable synchronous reading, writing. Possible values are "yes"
      18. # or no. Normally synchronous reading or writing should be slower than
      19. # asynchronous, so to save some time most people would say "no" here.

      ... bekomme ich folgende Fehlermeldung:

      Quellcode

      1. : not found1:
      2. : not found2:
      3. : not found6:
      4. expr: non-numeric argument
      5. ./nfs.sh: 39: Syntax error: word unexpected (expecting "do")

      Kennt jemand eine Lösung?
      Ich fnd das script interessant, weil bei den Testern mit höheren wsize- und rsize-Werten als 8192 eine bessere Performance erzielt wurde und man mit idealen Einstellungen noch ein paar Prozent Bandbreite rauskitzeln kann, welches ja für HD-Aufnahemn auf den NAS hilfreich sein könnte.
