Public bug reported: Currently the guided methods of the Ubuntu installer only address single disk setup. When a user have several disks on his machine he has to use the manual partitioning which is prone to failure for inexperienced users.
It would be useful to understand how many disks are installed on a system and their size to determine how update the installer to best suit users' needs. This information is available from /sys/block/<device>/size . The information is in blocks. The block size is available from /sys/block/<device>/queue/{logical|physical}_block_size For example on my system $ cat /sys/block/sda/{size,queue/*_block_size} 125045424 512 512 ProblemType: Bug DistroRelease: Ubuntu 18.10 Package: ubuntu-report 1.2.0 ProcVersionSignature: Ubuntu 4.15.0-23.25-generic 4.15.18 Uname: Linux 4.15.0-23-generic x86_64 ApportVersion: 2.20.10-0ubuntu7 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Mon Jul 30 14:42:25 2018 Dependencies: gcc-8-base 8.2.0-1ubuntu2 libc6 2.27-3ubuntu1 libgcc1 1:8.2.0-1ubuntu2 InstallationDate: Installed on 2014-07-15 (1476 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Alpha amd64 (20140520) SourcePackage: ubuntu-report UpgradeStatus: Upgraded to cosmic on 2018-03-24 (127 days ago) ** Affects: ubuntu-report (Ubuntu) Importance: Undecided Assignee: Didier Roche (didrocks) Status: Triaged ** Tags: amd64 apport-bug cosmic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1784383 Title: Collect number of disks and disk size To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-report/+bug/1784383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
