[Bug 1004243] Re: multipath installs not working

[Adam Conrad]

Some investigation here shows that libmultipath is underlinked, which is
accidentally worked around on installed systems via a library
dependency, but not in the d-i initrd.  Uploading a fix.

** Package changed: debian-installer (Ubuntu) => multipath-tools
(Ubuntu)

** Changed in: multipath-tools (Ubuntu)
     Assignee: (unassigned) => Adam Conrad (adconrad)

** Also affects: multipath-tools (Ubuntu Precise)
   Importance: Undecided
       Status: New

** Also affects: multipath-tools (Ubuntu Trusty)
   Importance: Undecided
       Status: New

Title:
  multipath installs not working

Status in “multipath-tools” package in Ubuntu:
  Confirmed
Status in “multipath-tools” source package in Precise:
  New
Status in “multipath-tools” source package in Trusty:
  New

Bug description:
  I started up a precise/netboot install using debian-
  installer_20101020ubuntu136 and disk-detect/multipath/enable=true and
  found that multipath support didn't appear to be working. That is to
  say, both paths appeared as separate disks in the installer, and no
  device-mapper devices were instantiated.

  I dropped to a shell and discovered that /sbin/multipath fails to run:

  BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash)
  Enter 'help' for a list of built-in commands.

  ~ # multipath
  multipath: symbol lookup error: /lib/libmultipath.so.0: undefined symbol: dlopen

  Note: this also seems to be the case in oneiric, though oneiric also
  has a bug where it does not appear to have the dm-multipath module
  available at install time.
