The 'wait-for-root' command won't guard for the events that the BLKRRPART ioctl generates.
BLKRRPART generates the following: ubuntu@srv-hgww8:~$ sudo udevadm --debug monitor --udev run_command: calling: monitor monitor will print the received events for: UDEV - the event which udev sends out after rule processing UDEV [1303300813.480716] remove /devices/pci0000:00/0000:00:06.0/virtio3/block/vdb/vdb1 (block) UDEV [1303300813.538753] change /devices/pci0000:00/0000:00:06.0/virtio3/block/vdb (block) UDEV [1303300813.570692] add /devices/pci0000:00/0000:00:06.0/virtio3/block/vdb/vdb1 (block) The 'wait-for-root' command is written presuming that there is no device entry in the database and you're just waiting for it to arrive. If it runs before the kernel has queued or processed the 'remove'event, then it will succeed in any event. The mount will then fail if it runs after the 'remove' event but before the 'add' event completes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/765843 Title: Intermittent mount failure after growroot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
