Status in cloud-init: Expired Status in cloud-init package in Ubuntu: Triaged Bug description: for provisioning ubuntu trusty on baremetal, cloud-init fails to grow root partition, below is the error. physical server is HP bl460c blade , booting from SAN and using multipath , ==================================== - cc_growpart.py[DEBUG]: No 'growpart' entry in cfg. Using default: {'ignore_growroot_disabled': False, 'mode': 'auto', 'devices': ['/']} - util.py[DEBUG]: Running command ['growpart', '--help'] with allowed return codes [0] (shell=False, capture=True) - util.py[DEBUG]: Reading from /proc/1005/mountinfo (quiet=False) - util.py[DEBUG]: Read 1121 bytes from /proc/1005/mountinfo - util.py[DEBUG]: resize_devices took 0.003 seconds - cc_growpart.py[DEBUG]: '/' SKIPPED: device_part_info(/dev/disk/by-label/cloudimg-rootfs) failed: /dev/disk/by-label/cloudimg-rootfs not a partition ==================================== upon checking seems like cc_growpart.py script is relying on "/sys/class/block/device-name/partition" file to check number of partitions. but for dm multipath devices , there is no such "partition" attribute exists, hence script error out saying "not a partition". I do not have any solution for now, but trying to find how to map multipath device like /dev/dm-1 to it's real scsi disk /dev/sda1 .. if that's figured out then we can put some logic to say if base name is dm-x then find mapped sdx and use that device to find a partition etc. is this just me or someone else also has this issue with cloud-init failing on multipath disks.
