Hi, the lustre manual says:
2.2.1.5 Stopping a Server To stop a server: $ umount -f /mnt/test/ost0 The '-f' flag means "force"; force the server to stop WITHOUT RECOVERY. Without the '-f' flag, "failover" is implied, meaning the next time the server is started it goes through the recovery procedure. So we were tempted to use "umount -f" when doing a failover of OSTs, but we see problems (I/O errors on clients) during the failover when doing this. Without the "-f" flag we get no I/O errors. Is there a recommended way of dealing with the umount at failover?
