1.8.9 Creating a regular file by mknod(2)

Do not perform the following operation in a GFS Shared File System.

If a regular file is created by mknod(2), the file open information cannot be managed normally. As a result, mmap(2) from other nodes to the file will fail, or the unused inode of the file will not be released when the file is deleted.

If the operation mentioned above is executed, mount again after unmounting the file system. It will resume the system operation.
