rsync over nfs makes omv unresponsive/crash

  • Hi there,
    after I finished the OMV installation, I tried to start a initial upload of my multimedia files.
    It is about 1,5TB, so I thought it would be smart to use rsync and nfs to achieve that. But after a few files ( ~ 1 GB in sum) I "lost" the nas.
    rsync on clientside stops or hangs without a error message. The Webinterface is no longer accessible and even ping says : icmp_seq=203 Destination Host Unreachable


    I tried to get out some info from the logs, but no luck.


    rsync is called via rsync -r --ignore-existing -P Videos/ nas/video/
    Permissions seems to be ok, i can write and delete on the mounted share


    Perhaps you have some ideas ?


    Thanks in advance
    Michael

  • update:


    If i run rsync over ssh, standard options:
    rsync -r --ignore-existing --progress Videos nas@nas:/media/<uuid>/shared/video/


    it seems to work, .... setting ssh options for better performance: rsync -e "ssh -T -c arcfour -o Compression=no -x" -r --ignore-existing --progre.... produces the error described above


    Transfers:
    with standard ssh: 734,359,552 100% 27.90MB/s 0:00:25
    with performance: 733,581,312 100% 79.54MB/s 0:00:08


    So if rsync eats up all the bandwith, working on a 1Gb LAN, why does the nas not come back to network ?

  • Finally, i found a solution :) ... to make it short, I installed kernel backports via omv-extras, everything works fine.


    In Detail:
    I'm using a ARock N3150-ITX Board and figured out, if i switch the LAN-Bandwith in my fritzbox settings (there is a option for 100Mbs (Greenmode) and 1GBs (Powermode)) to 100MBs, eveythings works fine, switching back to 1GBs, causes the networkdevice to stop working with out a message or notification. So I suppose it is network-driver related.
