Public bug reported: We're using bcache under trusty HWE kernel (3.16.0-38-generic) with bcache-tools 1.0.7-0ubuntu1 (built from src).
As trusty has util-linux 2.20.1, udev rules for auto registering bcache devices are skipped: # blkid was run by the standard udev rules # It recognised bcache (util-linux 2.24+) ENV{ID_FS_TYPE}=="bcache", GOTO="bcache_backing_found" We're manually cowboy'ing the following line alongside above: KERNEL=="nvme*", GOTO="bcache_backing_found" , but it would be great if something like trying bcache-register on non rotational devices were added to the udev rules: ENV{DEVTYPE}=="disk", ATTR{queue/rotational}=="0", GOTO="bcache_backing_found" ** Affects: bcache-tools (Ubuntu) Importance: Undecided Status: New ** Tags: canonical-bootstack -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to bcache-tools in Ubuntu. https://bugs.launchpad.net/bugs/1462466 Title: bcache-tools udev rules on trusty lacking util-linux 2.24+ workaround To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1462466/+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
