I'll ask Heinz-Werner to attach the logs and the screenshots from that mail conversation.
So you are using a DASD ECKD - since it has about 50 GB I assume it's probably a 3390 Model54 - I'll try to find a spare one for test and re- creation. The storage configuration screen should look like this: ================================================================================ Storage configuration [ Help ] ================================================================================ To continue you need to: Mount a filesystem at / AVAILABLE DEVICES ^ DEVICE TY┌─────────────────────────┐ [ LX0200 lo│< (close) │ partition 1 existing, already formatted as ext2,│ Info >│ mounted │ Reformat >│ partition 2 existing, unused │ Add VTOC Partition >│ │ Format >│ [ Create software RAID (md) > ] │ Remove from RAID/LVM │ [ Create volume group (LVM) > ] └─────────────────────────┘ │ │ USED DEVICES v [ Done ] [ Reset ] [ Back ] Based on the selected DASD (ECKD), specified by it's device name (here LX0200), the installer provides options to 'Add VTOC' (wipe out disk, too) and to (re-)format. The suggestion about 1GB for /boot and a 4GB for root is indeed too limited, and this got already addressed here: https://bugs.launchpad.net/subiquity/+bug/1785321 and further more fixed here: https://github.com/CanonicalLtd/subiquity/pull/737 This happened a while ago and the modification got already rolled out with subiquity 20.05.1 (https://github.com/CanonicalLtd/subiquity/releases/tag/20.05.1). Hence with current installations (of course in non-air-gapped environments) the subiquity installer looks for updates at the beginning and in case there is one, it let's you know and offers to update itself. The update screen comes with a message like "Version 20.05.1 of the installer is now available (20.04.3 is currently running)." Doing so and accepting to update, you shouldn't run into that issue with the small LVs anymore. ** Changed in: ubuntu-z-systems Status: New => Triaged -- 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
