Cause

This issue can occur if the permissions, owner, or both on the file /opt/vmware/vcloud-director/etc/cmt-logging.properties were modified.
The cell-management-tool runs using the vcloud user and this user must have access to the file for commands to complete.

Resolution

To resolve this issue, correct the ownership of the /opt/vmware/vcloud-director/etc/cmt-logging.properties file on the VCD Cell.

1. Change Directory to /opt/vmware/vcloud-director/etc/ where the cmt-logging.properties is located.

cd /opt/vmware/vcloud-director/etc/

2. Check the current permissions on the file.

ls -l cmt-logging.properties

An example of incorrect properties would be the following:
-r-------- 1 root root 2090 Apr  3 15:47 cmt-logging.properties

3. Change the owner to the vcloud user.

chown vcloud:vcloud cmt-logging.properties

4. Set the permissions on the file to the expected default.

chmod 640 cmt-logging.properties

5. Confirm that the owner and permissions are updated.

ls -l cmt-logging.properties

An example of incorrect properties would be the following:
-rw-r----- 1 vcloud vcloud 2090 Apr  3 15:47 cmt-logging.properties

6. Retry the cell-management-tool command which was previously failing, for example:

/opt/vmware/vcloud-director/bin/cell-management-tool -u administrator cell -t
