How to reproduce: we have a executable file on a read only mounted client: [root@client mnt]# ls -l /mnt/ total 8 -rwxr-xr-x 1 root root 6439 Feb 1 14:51 test [root@client mnt]# ./test Hello World! Then we try to write to the file, which will fail with EROFS: [root@client mnt]# echo foo >> ./test -bash: ./test: Read-only file system Then run the file again: [root@client mnt]# ./test -bash: ./test: Text file busy Note the executable fails to run across the whole cluster from this point, even on the clients without read only mount option. |
