      Description

      It appears that there are no "mdc.*.checksums,.checksum_type,.checksum_dump" parameters for MDC devices on the client. There are also no "mdd.*.checksum_t10pi_enforce,.checksum_dump" parameter on the MDS.

      However, looking at the "mdc.*.import" file shows a "cksum_type:" line, so it appears that the MDC and MDS are correctly negotiating the data checksum types:

      # lctl get_param *.*.import | egrep "c-f.*=|cksum_types:"
      mdc.testfs-MDT0000-mdc-ffff8b4c8502f000.import=
             cksum_types: 0xf7
      mdc.testfs-MDT0001-mdc-ffff8b4c8502f000.import=
             cksum_types: 0xf7
      osc.testfs-OST0000-osc-ffff8b4c8502f000.import=
             cksum_types: 0xf7
      osc.testfs-OST0001-osc-ffff8b4c8502f000.import=
             cksum_types: 0xf7
      osc.testfs-OST0002-osc-ffff8b4c8502f000.import=
             cksum_types: 0xf7
      osc.testfs-OST0003-osc-ffff8b4c8502f000.import=
             cksum_types: 0xf7
