I think your ZFS setup should work fine, but I don't know about your specific hardware. You must have hardware problems -- not necessarily in the SATA controller though. The block checksum mismatches suggest that the wrong data was written to the disk. Have you got EC RAM? Have you run Memtest86? __Martin ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
