15.14. Troubleshooting USB Storage

15.14.1. Problem: Device nodes are not created.
15.14.2. Problem: The device is not automatically mounted.
15.14.3. Problem: The device is not automatically unmounted.

15.14.1. Problem: Device nodes are not created.

Check the log file /var/opt/SUNWut/log/utstoraged.log for a message about why device nodes were not created. Some mass storage device types are not supported.

15.14.2. Problem: The device is not automatically mounted.

Check the log file /var/opt/SUNWut/log/utmountd.log for an error message.

This condition occurs when the Sun Ray operating system does not recognize the storage devices's file system.

15.14.3. Problem: The device is not automatically unmounted.

This condition occurs when a user still has an open reference to the mount point at the time the storage device is unplugged or the user's session is disconnected. The mount point becomes a stale mount point and persists until the system is rebooted or until the administrator removes it.

15.14.3.1. How to Find and Remove Stale Mount Points

  1. Search for stale mount points:

    # utdiskadm -s
  2. For each stale mount point, close all references to the mount point.

  3. For each stale mount point, terminate all processes that refer to the mount point.

  4. Remove the mount point.

    # umount stale_mount_path
