Invalid block size is used by zowe files create data-set-sequential

[plavjanik]

When I allocate a new dataset without specifying a block size is uses a default that is not a valid size and the allocated dataset is not usable.

zowe files create data-set-sequential DSN --recfm VB --lrecl 32756
Data set created successfully.

When I use the dataset in a JCL, it fails:

11.05.34 JOB98529  IEC141I 013-20,IGG0191A,PLAPECHW,,ZLDATA,8F26,WRKD22,  441

The explanation of the code is:

    S013-20
        An OPEN macro instruction was issued for a sequential data set using
        queued access. BLKSIZE is not a multiple of LRECL, or LRECL is 0 with
        RECFM=FB or RECFM=FBS, or BLKSIZE is not at least four bytes greater
        than LRECL with RECFM=V.

It is allocated as:

I would expect to do what ISPF allocates in this case (block size is 32760 which is record length + 4 because it is VB) :

Thank you for creating a bug report. If you haven't already, please ensure you have provided steps to reproduce it and as much context as possible.

Fixed in the v2.10 release.
