OK. There are multiple problems here. 1) parted has stopped probing DM devices that aren't DM-RAID. partman-base needs it to support this. 2) partman parses the output of 'multipath -l' to decide whether a device is a multipath device. Foolishly, multipath prints errors to standard output, such as a complaint about dm-multipath not being loaded. 3) dmraid-udeb depends on multipath-udeb for kpartx. There is no kpartx-udeb.
For 1), I'm going to restore this support; it's part of parted's interface now and shouldn't be broken. For 2), mostly we avoid this because we only ever install multipath-udeb in code that modprobes dm-multipath, but dmraid-udeb just broke this assumption. Fixing this properly seems fiddly, not least because I can't test that I haven't broken multipath in the process, so I'm inclined to just restore this assumption by creating kpartx-udeb and having dmraid-udeb depend on that. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/922646 Title: precise alternate LVM failed to install: no root file system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dmraid/+bug/922646/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
