fdasd on resized DASD leads to BUG statement and fdasd can not fix this disk

[stefan-haberland]

When a DASD device gets resized and formatted using dasdfmt -M expand calling fdasd afterwards might lead to the following BUG statement:

BUG: specified free space extent for deleting not found in FMT5/7 DSCB!

Afterwards fdasd is not able to use the expanded portion of the disk.

Workflow to recreate:

1. resize DASD
2. call dasdfmt -M expand /dev/dasdX
3. call fdasd in interactive mode
   • r - re-create VTOC and delete all partitions
   • re create old partitions
     OR
   • u - re-create VTOC re-using existing partition sizes
4. try to create new partition
   -> BUG

NOTE:
It works if fdasd is only called in interactive mode to "r - re-create VTOC and delete all partitions" and the re-creation of the partition layout is done using fdasd -c CONFIGFILE.
