[Touch-packages] [Bug 696435] Re: wait-for-root fails to detect nbd root
This bug was fixed in the package systemd - 229-4ubuntu21.2 --- systemd (229-4ubuntu21.2) xenial; urgency=medium [ Dimitri John Ledkov ] * udev: Mark ndb devices as inactive until connected. (LP: #696435) * networkd: in dhcp, change UseMTU default to true, to accept DHCP provided MTU by default. (LP: #1717471) * sysctl: apply parameters in-order, instead of randomly. (LP: #1718444) * networkd: apply promote_secondaries, to make DHCP lease changes work. (LP: #1721223) * shutdown: sync filesystems, before going into a killing spree. (LP: #1722481) * sysctl: do not fail, when cannot apply sysctl changes due to read-only sysfs in containers. (LP: #1734409) * networkd,wait-online: add RequiredForOnline to mark mandatory/optional links for boot. (LP: #1737570) [ David Glasser ] * journald: don't reduce BurstRateLimit on low disk space (LP: #1732803) -- Dimitri John Ledkov Wed, 21 Feb 2018 13:46:37 + ** Changed in: systemd (Ubuntu Xenial) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/696435 Title: wait-for-root fails to detect nbd root Status in linux package in Ubuntu: Fix Released Status in nbd package in Ubuntu: Invalid Status in systemd package in Ubuntu: Fix Released Status in linux source package in Xenial: Fix Released Status in systemd source package in Xenial: Fix Released Bug description: [Impact] Kernel does not generate any events when ndb-client connects /dev/nbd0 devices, therefore it is impossible to monitor/react to the state of /dev/nbd0.

Hello Alkis, or anyone else affected, Accepted systemd into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/229-4ubuntu21.2 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

Hello, I will retest this with the sru kernel. The udevadm monitor appears to monitor things that it knows about thus first one needs to load nbd module, start monitor, unload nbd module, then proceed with the test case.

[Touch-packages] [Bug 696435] Re: wait-for-root fails to detect nbd root
I'm the bug reporter, and I have a problem in doing the verification. a) The initial testcase that I reported happens in both 4.4 unpatched and 4.10. I.e. the bug that I reported is not yet fixed. b) Some Ubuntu developer wrote a new testcase as part of doing the SRU. I cannot reproduce that testcase neither in 4.4 unpatched nor in 4.10, i.e. `udevadm monitor` does show add/change events for nbd devices for me in both kernels. I.e. that sounds like a different bug that I never saw.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
