I've written a dtrace script to get the checksums on Solaris 10. Here's what I see with NFSv3 on Solaris 10. # zoneadm -z zone1 halt ; zpool export pool1 ; zpool import -d /mnt/pool1 pool1 ; zoneadm -z zone1 boot ; sleep 30 ; pkill dtrace # ./zfs_bad_cksum.d Tracing... dtrace: error on enabled probe ID 9 (ID 43443: fbt:zfs:zio_checksum_error:return): invalid address (0x301b363a000) in action #4 at DIF offset 20 dtrace: error on enabled probe ID 9 (ID 43443: fbt:zfs:zio_checksum_error:return): invalid address (0x3037f746000) in action #4 at DIF offset 20 cccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccdtrace: error on enabled probe ID 9 (ID 43443: fbt:zfs:zio_checksum_error:return): invalid address (0x3026e7b0000) in action #4 at DIF offset 20 cccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc Checksum errors: 3 : 0x130e010111000003 0x2010800000000 0x0 0x400 (fletcher_4_native) 3 : 0x2200000125cd8000 0x600002425980c08 0x16630c08296c490c 0x82b320c082aef0c (fletcher_4_native) 3 : 0x2f2a0a202a20436f 0x7079726967687420 0x2863292032303031 0x2062792053756e20 (fletcher_4_native) 3 : 0x3c21444f43545950 0x452048544d4c2050 0x55424c494320222d 0x2f2f5733432f2f44 (fletcher_4_native) 3 : 0x6005a80000389144 0xc2080e6405c200b6 0x960093d400000800 0x9eea007b9800019c (fletcher_4_native) 3 : 0xac044a6903d00163 0xa138c80034000046 0x3f2cd1e100b10009 0xa37af9b5ef166104 (fletcher_4_native) 3 : 0xbaddcafebaddcafe 0xc 0x0 0x0 (fletcher_4_native) 3 : 0xc4025608801500ff 0x1018500704528210 0x1901000003e50066 0xc34b90001238f900 (fletcher_4_native) 3 : 0xfe00fc01fc42fc42 0xfc42fc42fc42fc42 0xfffc42fc42fc42fc 0x42fc42fc42fc42fc (fletcher_4_native) 4 : 0x4b2a460a 0x0 0x4b2a460a 0x0 (fletcher_4_native) 4 : 0xc00589b159a00 0x543008a05b673 0x124b60078d5be 0xe3002b2a0b605fb3 (fletcher_4_native) 4 : 0x130e0101110000 0x32000b301080034 0x10166cb34125410 0xb30c19ca9e0c0860 (fletcher_4_native) 4 : 0x130e0101110000 0x3a0000201080038 0x104381285501102 0x418016996320408 (fletcher_4_native) 4 : 0x130e0101110000 0x3a0000201080038 0x1043812c5501102 0x81802325c080864 (fletcher_4_native) 4 : 0x130e0101110000 0x3a0001c01080038 0x1383812c550111c 0x818975698080864 (fletcher_4_native) 4 : 0x1f81442e9241000 0x2002560880154c00 0xff10185007528210 0x190100000003e566 (fletcher_4_native) 5 : 0xbab10c 0xf 0x53ae 0xdd549ae39aa1ba20 (fletcher_4_native) 5 : 0x130e0101110000 0x3a0000b01080038 0x1163812c550110b 0x8180a7793080864 (fletcher_4_native) 5 : 0x6162630000000000 0x0 0x0 0x0 (fletcher_4_native) 5 : 0x8000000000000003 0x3df0d6a1 0x0 0x0 (fletcher_4_native) 6 : 0xbab10c 0xf 0x5384 0xdd549ae39aa1ba20 (fletcher_4_native) 7 : 0xbab10c 0xf 0x0 0x9af5e5f61ca2e28e (fletcher_4_native) 7 : 0x130e0101110000 0x3a0000201080038 0x104381265501102 0xc18c7210c086006 (fletcher_4_native) 7 : 0x275c222074650a2e 0x5c222020436f7079 0x7269676874203139 0x38392041540a2e5c (fletcher_4_native) 8 : 0x130e0101110000 0x3a0003101080038 0x1623812c5501131 0x8187f66a4080864 (fletcher_4_native) 9 : 0x8a000801010c0682 0x2eed0809c1640513 0x70200ff00026424 0x18001d16101f0059 (fletcher_4_native) 12 : 0xbab10c 0xf 0x0 0x45a9e1fc57ca2aa8 (fletcher_4_native) 30 : 0xbaddcafebaddcafe 0xbaddcafebaddcafe 0xbaddcafebaddcafe 0xbaddcafebaddcafe (fletcher_4_native) 47 : 0x0 0x0 0x0 0x0 (fletcher_4_native) 92 : 0x130e010111000003 0x1010800000000 0x0 0x200 (fletcher_4_native) Since I had to guess at what the Solaris 10 source looks like, some extra eyeballs on the dtrace script is in order.
