      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
