[Bug 1503286] Re: ISST-LTE: Boot of Ubuntu15.10 lpar fails: "mounting /dev/sdn2 on /root failed: Device or resource busy" [multipath]

[Launchpad Bug Tracker]

This bug was fixed in the package multipath-tools - 0.4.9-3ubuntu7.9

---------------
multipath-tools (0.4.9-3ubuntu7.9) trusty; urgency=medium

  * debian/patches/kpartx-support-device-names-with-spaces.patch: fix loopback
    files unmapping. (LP: #1543430)

multipath-tools (0.4.9-3ubuntu7.8) trusty; urgency=medium

  * debian/patches/kpartx-support-device-names-with-spaces.patch: deal with
    spaces in device names in kpartx too (LP: #1432062)
  * debian/initramfs/local-premount: wait for udev to settle before mounting
    so the by-uuid/ symlinks have a chance to be updated by udev rules.
    (LP: #1503286)
  * Allow device detection all through the initramfs: run multipathd instead
    of only scanning once for devices, so those that come up slower can still
    be used as a root device (LP: #1526984):
    - debian/patches/0050-readonly-bindings_prefix.patch,
      debian/patches/0051-readonly-bindings_multipath.patch,
      debian/patches/0052-readonly-bindings_multipathd.patch,
      debian/patches/0053-readonly-bindings_multipathd_prod.patch: support -B
      to allow multipathd to handle cases where the bindings file is read-only.
    - debian/initramfs/hooks: install multipathd and required directories.
    - debian/initramfs/local-premount: also reload all maps to make sure
      they're ready before we mount.
    - debian/initramfs/local-top: run multipathd rather than a one-off call to
      multipath so that new paths can be correctly added as detected while
      we're still in the initramfs.
    - debian/initramfs/local-bottom: remember to stop multipathd.
    - debian/initramfs/local-bottom, debian/rules: install local-bottom for
      initramfs.
  * debian/patches/lp1496210_add_IBM_XIV_defaults.patch: add support (default
    config values) for the IBM 2810XIV storage system. (LP: #1496210)
  * debian/patches/0054-kpartx-update-option.patch: run kpartx -u rather than
    kpartx -a, so as to remove old partition entries if the partition table
    has changed. (LP: #1473903)
  * debian/patches/multipath_enable_sync_support_1b8082c8.patch,
    debian/patches/kpartx_rely_on_udev_dev_creation_9a632fff.patch: synchronize
    udev, device-mapper and multipath, and let udev deal with creating device
    nodes and symlinks. (LP: #1486370)
  * debian/initramfs/local-top: drop scsi_wait_scan stanza, that module is no
    longer available. (LP: #1538775)
