open(2) and mmap(2) that cannot be maintain the consistency of the data were issued to the same file.
Response
Please wait for the termination of the process running on the "node1" indicated this message, and execute again.
To determine the process using the i-number, act according to the following sequence:
determine the filename of the i-number, using find(1) with -inum option.
determine the process ID that uses the filename, using fuser(1).
determine the command name of the process ID, using ps(1).

Response
Take action according to the instructions in "C.3.1 Action for I/O errors."
Explanation
The size of the partition which constitutes the file system (fsid) might have been changed.
Response
Perform the procedure (from step 6 on) described on "C.3.2 Corrective action in the event of data inconsistency."
GFS Shared File System can not be expanded by size expansion of the partition which shares the GFS Shared File System. Perform the procedure above promptly.
Explanation
