    Your data volume is very full. You should try to keep it under 80% full.

     

    Also RAID-0 is not recommended. It would be much better to use e.g. RAID-10.

      Hi,

       
      I tried using raid5 now and a iscsi file with 75% of the total size of the raid, I still get the same error.
      I've sent a new log file.
       
      There are reports of similar problems with iscsi to be found on google, usually the suggested workaround is to change vm.zone_reclaim_mode to 1. However I cannot find that file in /proc on the NAS.
       
       
       
      Best regards,
       
      Andreas
