[Bug 1906384] Re: [UBUNTU 18.04] lvm boot failure
Well, if multipath in configured in the right way, the initramfs can be rebuild for example with: sudo update-initramfs -k all -u But additional paths also means additional (FCP) devices needed. You need to make sure that these additional devices are in place and configured in a persistent way using chzdev and available in the early boot cycle. So if you call chzdev to activate the additional FCZ devices and you add the arguments "-p -r zdev:early", the initramfs rebuild is automatically triggered for you. On top make sure you have multipath-tools-boot installed (in add. to multipath-tools). But doing that during the installation is of course the more convenient (and less error prone) way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1906384 Title: [UBUNTU 18.04] lvm boot failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1906384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1906384] Re: [UBUNTU 18.04] lvm boot failure
Do you remember what happened just prior to the reboot - have you been upgrading the system with a new kernel and/or updated packages? (Btw. the kernel 4.15.0-91 is a bit outdated, current is 4.15.0-124.) There's maybe a file /etc/lvm/lvm.conf.dpkg-dist available from a previous upgrade. Or have you added more or changed FCP or iSCSI disks to the system, that may have let to a name clash or device (path) discovery order issues? And was the initramfs rebuild? Such an issue can also happen due to temporarily unavailable paths or devices, and there seem to be some of them in that system. Do you have LUN masking (zoning) in your SAN in place, so that the host can only see the LUNs it's supported to see? Btw. I think in your filter rule you also want to accept the sd* (SCSI/FCP) devices, so: filter = [ "a|/dev/sd*|", "a|/dev/mapper/mpath*|", "r|.*|" ] and you may add the same as global filter: global_filter = [ "a|/dev/sd*|", "a|/dev/mapper/mpath*|", "r|.*|" ] for system level scans. According to the logs the system seems to expect '/dev/mapper/ISVCL1--vg', so looks you have LVM on top of multipath? ** Changed in: ubuntu-z-systems Importance: Undecided => Medium ** Changed in: ubuntu-z-systems Assignee: (unassigned) => Skipper Bug Screeners (skipper-screen-team) ** Changed in: linux (Ubuntu) Assignee: Skipper Bug Screeners (skipper-screen-team) => (unassigned) ** 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/1906384 Title: [UBUNTU 18.04] lvm boot failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1906384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
