So, just to catch this bug up with where Oleg and I are. a.) curtin installs multipath-tools-boot into the target with /dev, /proc and /sys mounted. However, it has disabled services from starting through ChrootableTarget's allow_services=False [1]. That uses disable_services_in_root [2]. b.) the way /etc/multipath/bindings is normally created is through the multipath daemon running
So, since we've blocked 'b', we dont get the file created and it doesn't get collected into the initramfs. To solve this, we'll need to run a blocking command with no other side effects in the chroot that creates /etc/multipath/bindings. Oleg found that that can be accomplished with /multipath -r'. sudo sh -c 'rm -Rf /etc/multipath && multipath -r >/dev/null && ls -l /etc/multipath/bindings' Last thing, a minor point, there is a race condition in the normal install path that could lead to initramfs not collecting /etc/multipath/bindings. This is because the daemon is started in the background, and is not guaranteed to create /etc/multipath/bindings before update-initramfs is run by the trigger. -- [1] http://bazaar.launchpad.net/~curtin-dev/curtin/trunk/view/head:/curtin/util.py#L289 [2] http://bazaar.launchpad.net/~curtin-dev/curtin/trunk/view/head:/curtin/util.py#L257 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1462530 Title: multipath errors on vivid and wily kernel? Status in linux package in Ubuntu: Confirmed Bug description: Oleg and I got changes into curtin to fix bug 1371634. So that now we can boot into multipath iscsi devices on power. It seems to go well enough with trusty+hwe-u, but when trying vivid, I am seeing errors.
