Is the NVMe drive with or without nvme-multipath support? Does it help to disable multipath?
Please see the below pullrequest from Canonical employee in efivar project that explains the issue a bit, and the various paths that the NVMe devices can have. https://github.com/rhboot/efivar/pull/158 This also affected efibootmgr project for the EFI platforms with newer kernels, as shipped in focal. You can also try booting with the following kernel cmdline option appended in the param file i.e. `nvme_core.multipath=N` to get the "non- multipath nvme0 nodes in the sysfs". BTW https://www.ibm.com/support/knowledgecenter/STSLR9_8.3.1/com.ibm.fs9100_831.doc/svc_fc_nvme_multipathconfighosts.html has an excellent summary of nvme multipath situation in various distros. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1902179 Title: [20.04 FEAT] Support/enhancement of NVMe IPL To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1902179/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
