[Bug 1280881] Re: Does not detect hotplugged storage device (WD Elements 1TB)

[Adrian Frith]

As requested:

# blkid -p /dev/sdb1
/dev/sdb1: LABEL="ElementsSmall" UUID="6822170D55D13F29" TYPE="ntfs" USAGE="filesystem" PART_ENTRY_SCHEME="dos" PART_ENTRY_TYPE="0x7" PART_ENTRY_NUMBER="1" PART_ENTRY_OFFSET="2048" PART_ENTRY_SIZE="1953456128" PART_ENTRY_DISK="8:16"

There is definitely a partition and a filesystem there, since I can
manually mount the filesystem using 'mount' on the commandline. Here is
the partition table from 'fdisk':

# fdisk -l /dev/sdb
Disk /dev/sdb: 1000.2 GB, 1000170586112 bytes
38 heads, 40 sectors/track, 1285169 cylinders, total 1953458176 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Title:
  Does not detect hotplugged storage device (WD Elements 1TB)

Status in “systemd” package in Ubuntu:
  Incomplete

Bug description:
  My WD Elements 1TB drive does not automatically mount when connected,
  although I can mount it manually with 'mount'.

  Some things I have noticed:

  1. While the device /dev/sdb1 (for the only partition on the drive) is created, it is given permissions 600 and belongs to group root, whereas for other drives the device is given permissions 660 and belongs to group disk.
  2. The usual symlinks to the device are not created in /dev/disk/by-uuid/ or /dev/disk/by-label/.
  3. This problem appeared with the out-of-the-box partition table; I have blanked the first 100MB of the disk with dd, recreated the partition table and reformatted, but it still happens.
  4. 'udevadm info /dev/sdb1' gives very perfunctory output for this drive, compared to the copious output for other drives.
  5. 'udisksctl info -b /dev/sdb1' responds 'Error looking up object for device /dev/sdb1'.
