It's possible (if unlikely) that you are only getting checksum errors on metadata. Since ZFS always internally mirrors its metadata, even on non-redundant pools, it can recover from metadata corruption which does not affect all copies. (If there is only one LUN, the mirroring happens at different locations on the same LUN.)
I thought about that but looking at the NFS server the real data should be much much more than metadata so I would consider it unlikely. Also in the now redundant setup we see checksum errors on both attached RAIDs
Any hints on how to track down the problem to the HBA, cables, RAID and so on? We see similar things on all our machines with few exceptions. Talking to local Sun folks we have been "warned" before that checksum errors will show up and that it's considered normal. Nevertheless I really want to know what they are about
