[HPDD-discuss] Clean shutdown

Hi there, We are running a small lustre system (1MGS/MDS + 2 OSTs). I haven't found the information, so i ask you : What is the good order to shutdown the whole system (for electrical maintenance ...) when you run a combined MGT/MDT : - disconnect the clients - is there any way to check if there is a client still connected ? - unmount the MGT/MDT - unmount the OSTs - ... poweroff all the servers - mount the OSTs - then the MGT/MDT - then the clients ? or should I stop the ost first and mount them last ?
