Adding a minor mention in the LP Bug, as we had a customer being affected by the issue while installing 20.04.1 on a z14, atop of z/VM 6.4, using unformatted 3390-M9s.
The workaround provided by Herr Heimes on LP Bug #1878596, Comment #21, has proven to be a workaround for the issue. I believe we should either check for the current format of the disk on z/VM (that's not filesystem formatting, as Heimes pointed out, but rather a low-level format of the ECKD to be used) using lszdev/lsdasd then use dasdfmt, or point out in the docs we should have someone run CPFMTXA in z/VM to add CDL to the DASD, enabling its usage by the Guest. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878596 Title: [Ubuntu 20.04] - Install - problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1878596/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
