-              * Drives lost connection, got stuck. Required a thorough reboot (reboot drives didn't work), reboot system then a 2min wait+[drives on]+operate+source=disable+antenna=open+antenna=operate worked ​(Lucas). +              * Drives lost connection, got stuck (Lucas). 
-              * Flexbuffke got into a nasty state and wasn't happy. ​The first sign was the data rate on Grafana went from the '​normal'​ smooth 3Gbps scans to ugly, spiky and somewhat random data rates. Another sign was the number of dropped packets in “mk5=evlbi?​” – maybe we should add this to katherine midob? +              * Flexbuffke got into a nasty state and wasn't happy (Lucas)
-              * The current fix is to (halt obviously), umount all the drives, remount them, restart jive5ab and re-setupsx. On flexbuffke there are two scripts in /tmp/. After logging in as su (ssh observer@flexbuffke then su in random terminal), run script /​tmp/​UMountAllFlexbuff.sh; wait make sure they all unmount, then run /​tmp/​MountAllFlexbuff.sh. After this you need to go to the flexbuffke jive5ab window (normally running on the vnc, with lots of “Reply: !”–type stuff) ​and ctl-C OR just pkill jive5ab from observer@flexbuffkeThen restart ​by up-arrowing or typing “/​opt/​jive5ab-2.9.0 -m2 &” or maybe …“-3.0.0” jury is out which one atm. Then setupsx in the field system ​and make sure the datarate is okay and “mk5=evlbi?​” looks happy and is increasing (Lucas).+              * The current fix is to (halt obviously), umount all the drives, remount them, restart jive5ab and re-setupsx (Lucas). 
 +                  * Due to wet season ​and power outagesHave to restart the connection ​and Fluxbuff.
