We have exported Lustre file system via NFS (let's say from n1).

The attached script 'repr.sh' creates the executable 'test.sh' on the Lustre folder, then connects to n1 by ssh and executes the created script 'test.sh' on n1.

The script 'repr.sh' always results with the error "bash: /folder_on_lustre/test.sh: Text file busy"

Reproducing script:
cd /folder_on_lustre
rm -rf test.sh
echo "ls -l" >> test.sh
chmod +x test.sh
echo "ls" >> test.sh
ssh -o 'StrictHostKeyChecking no' n1 '/folder_on_lustre/test.sh'
