[parted-devel] [Parted-maintainers] Debian Bug #578097: No support for CMS-formatted disks

[Stephen Powell]

OK, I have LDL disks working with the DIAG driver in parted now.
The reason I was having trouble yesterday was that the LDL disk I
was using for testing was formatted by a very old version of dasdfmt.
Debian Squeeze currently uses version 1.6.2 of s390-tools.  I upgraded
to version 1.8.3 from Sid and reformatted the disk.  This version uses
the "version 2" format of an LDL disk label, which contains the number
of formatted blocks in the label.  Without this information in the label,
which the old version of dasdfmt did not supply, parted relies on
device geometry to calculate the size of the partition.  And device
geometry is all bogus when using the DIAG driver.  Upgrading to a
newer version of s390-tools and reformatting the disk solved the problem.

Now on to the final frontier: FBA DASD.
