I beleive I have found the problem. I tried to define a raid-5-volume on the arc-1680-card and still saw errors as mentioned above. Areca-support suggested that I upgraded to the lastest solaris-drivers (located in the beta-folder) and upgraded firmware as well. I did both and it somewhat solved my problems but I had very poor write-performance, 2-6 MB/s. So I deleted my zpool and changed the arc-1680-configuration and put all disks in passthrough-mode. I created a new zpool and performed similar tests and have not experienced any abnormal behaviour. I'm re-installing the server with FreeBSD and will do similar tests and report back. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner.
