[SRU] bcache-tools to trusty and precise

Not currently a priority for ~canonical-server, but if someone else wants to drive this then that's fine.

We need this in trusty to support deploying Trusty with MAAS using Bcache storage configuration. Please backport bcache-tools.

This should actually be a priority for canonical-server. The support for bcache comes as a priority across all parts of the company and this is part of the features that curtin will support for this cycle.

This was a decision made in Annecy at the mid-cycle sprint!

Thanks

wily has bcache 1.0.8, there are no major changes to bcache itself [1] save fixes for working in systemd pre-boot environments, which for trusty won't matter; there are a number of package fixes[2] related to 1.0.8 intriduction of a bcache_register program introduced for systemd preboot support. I don't see any compelling reason to use 1.0.8 in trusty over what's already in vivid and tested (1.0.7);

    bcache-register: use register, not register_quiet

    register_quiet doesn't report errors correctly, the following kernel
    patch needs to be applied: https://lkml.org/lkml/2013/8/26/549

    See http://thread.gmane.org/gmane.linux.kernel.bcache.devel/2594
    for how this comes up in practice.

    Replace bcache-register with c, use builtin kmod

    In a pure systemd pre-boot environment, register-bcache can't be shell
    code as there is no shell available. Switch to loading the module with
    udev's builtin kmod support and introduce a small binary for registering
    devices.

    Gabriel: Changed errors to be verbose

Now that this is in trusty we also need this in Precise. Without this MAAS will not be able to deploy Precise at all, because of curtin needing bcache-tools.

Status changed to 'Confirmed' because the bug affects multiple users.

bcache-tools_1.0.7-1~12.04.1 (in my ppa) has been tested and is known to work. I'll be uploading that to precise-proposed shortly.

Hello Scott, or anyone else affected,

Accepted bcache-tools into precise-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/bcache-tools/1.0.7-1~12.04.1 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 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 to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Version 1.0.7-1~12.04.1 works on precise, with the needed (hwe-t) kernel.

This bug was fixed in the package bcache-tools - 1.0.7-1~12.04.1

The verification of the Stable Release Update for bcache-tools has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

curtin at revno 333 or better has support for bcache on 12.04.

This bug is believed to be fixed in curtin in 17.1. If this is still a problem for you, please make a comment and set the state back to New

Thank you.

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
