+ | * changeDataDir_maintainRunNum <data dir> : keeps the Run number the same, for when we need to move physics experiment data collection to another disk | ||
+ | * changeDataDir_resetRunNum <data dir> : finds the lowest available Run number without any larger RunDir #s | ||

+ | * S800 is losing events. Check the network speed of spdaq45 by /sbin/ethtool eth0 and /sbin/ethtool eth1 , both should show speed as 1000Mb/s, if one shows 100Mb/s then the network is too slow and S800 cannot send data to GEB fast enough which will cause event loss happen. | ||
+ | * Check the ringbuffer status, $DAQBIN/ringbuffer status - -host=spdaq45 - -all , if the free colum becomes zero, DAQ related people needs to be notified for diagnostics. | ||
