What does it mean when a GFS file system is withdrawn?
If a GFS file system detects corruption due to an operation it has just performed, it will withdraw itself. The idea of withdrawning from GFS is just slightly nicer than a kernel panic. It means that the node feels it can no longer operate safely on that file system because it found out that one of its assumptions is wrong. Instead of panicking the kernel, it gives you an opportunity to reboot the node “nicely”.
