[Bug 1595495] Re: DASD drives can only hold 3 partitions

[Launchpad Bug Tracker]

This bug was fixed in the package partman-base - 187ubuntu2.1

---------------
partman-base (187ubuntu2.1) xenial; urgency=medium

  * On s390[x], Prevent using extended partitions on DASD drives that can
    only hold 3 partitions. Parted doesn't have special knowledge about
    that and claims that msdos partition table on DASD drives can hold
    usual maximum number of partitions types. LP: #1595495.

Title:
  DASD drives can only hold 3 partitions

Status in partman-base package in Ubuntu:
  Fix Released
Status in partman-base source package in Xenial:
  Fix Released

Bug description:
  [Impact]

   * DASD drives have two types ECKD and FBA.
   * ECKD have been made to use dasd partition table by default, however can be used with msdos partition table
   * FBA devices use msdos partition table by default
   * Both types of drives can only hold 3 partitions
   * However parted/partman default to using logical partitions with default installation recipe, thus exploading instalations.

  [Test Case]

   * Start the installer, activate ECKD and/or FBA devices
   * In case of ECKD choose to use msdos partition table (label)
   * The installer should only create primary partitions, and not offer to create logical partitions in any way
