| The Flexbuff is our new data recorder, designed to handle VGOS data at 16+ Gbps recording rates. We're testing it out during AUSTRAL15 at 1 Gbps. It records to a large interal array of hard drives rather than a special diskpack as in the mark5b. | The Flexbuff is our new data recorder, designed to handle VGOS data at 16+ Gbps recording rates.

| - | The recorder is being controlled by a "spare" pcfs machine - pcfsho. It's running the a1501hb.snp snap file to get the correct scan names and recording times. There is a VNC session running on this machine which can be viewed with "vncviewer pcfsho:1". The FS output will likely be displaying a large number of errors which can be safely ignored. | + | The recorder is being controlled by a "spare" pcfs machine - pcfsho.

It will return "inactive" between scans and should return the word "active" and a recording pointer which is steadily increasing on repeated checks.

| - | * If you need to resynchronise the Hobart DBBC, please "halt" the schedule on pcfsho and issue the "disk_record=off" commands. You should not resume the flexbuff recordings until the flexbuff/flia10G resynchronisation is complete. There are some notes on this below, but it's probably best to contact Jamie M until a better solution is available. | + | * If you need to resynchronise the Hobart DBBC, please "halt" the schedule on pcfsho and issue the "disk_record=off" commands.
