    • Environment:
      A 216-way Thor overwriting a 312-part logical file hosted on a 312-way server

      Description

      Errantly ... though it seems like is should have worked (or failed) ... I specified "CLUSTER('thor_dev312')" when my 216-way Thor OUTPUT logical files which had the same logical name as logical files previously written locally by my 312-way Thor named thor_dev312.

      Though the operation appears to have succeeded, the logical files cannot be read ... and produce an error similar to the following when accessed:

      System error: 0: Graph[1], SLAVE #152 [172.31.25.201:6757]: Graph[1], diskread[2]: Failed to open block compressed file '//172.31.17.227:7100/var/lib/HPCCSystems/hpcc-data/thor/temp/did/disam_salt_v02/it1._220_of_312'
      

      The IP address specifies the 312-way system ... the file part exists, but is <zero> length. All file parts for slaves numbered beyond 216 are <zero> length. I'll attach a screen grab from one node. A number of files were output by this work unit with this pattern. None are readable afterwards. XREF displays some Warnings, but identifies no correctable errors.
