I run the same steps as Christian did and observed the same symptoms. However
> [...] the installer properly detected the disk state. Only on actually going to deployment did it crash. Yes, it crashes but the state of the disks were not correctly detected during the second install. Instead of a single multipath disk, it detected two separate disks with the same label, offering to partition each disk separately. See the list of "USED DEVICES" in https://bugs.launchpad.net/subiquity/+bug/2080474/comments/48 compared to https://bugs.launchpad.net/subiquity/+bug/2080474/comments/47. The type "local disk" should also be "multipath device". The installation errors when we attempt to run `lvcreate`: Running command ['lvcreate', 'ubuntu-vg-1', '--name', 'ubuntu-lv', '--zero=y', '--wipesignatures=y', '--yes', '--size', '6706692096B'] with allowed codes [0] (capture=False) WARNING: Not using device /dev/sda3 for PV 5tXJHt-wdEZ-WBCP-BFQ6-GVGL-IyWe-UUH32z WARNING: PV 5tXJHt-wdEZ-WBCP-BFQ6-GVGL-IyWe-UUH32z prefers device /dev/sdb3 because device is used by LV. Cannot update volume group ubunt-vg-1 with duplicate PV devices. Now, the crash is different from what was originally reported (here's it's failing when installing vs the original report is about failure during detection). But I suspect that being unable to see the device has a multipath device is at least part of the problem in both scenarios. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2080474 Title: ubuntu installation failing for systems having SAN disk To manage notifications about this bug go to: https://bugs.launchpad.net/subiquity/+bug/2080474/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
