[Planetlab-devel] Minimum disk size per MyPLC node

[Thierry Parmentelat]

Hi Brett

how did you turn off hardware check ? the recommended method is to have the node model field end with /minhw 

if that's what you did: my feeling is that there is a limit (I would say in the 16 Gb) that is - rather arbitrarily - used to decide whether a given device is a removable/usb unit or not; I know, that sounds a bit off, there should be better means to make this decision, but again I *think* this is how the code behaves. IIRC we came across somebody with a 16 Gb memory stick (yeah...) and made this change in a rush...

I'm afraid that turning off minimum hardware requirement check does not alter that, even if the error message does not fit this conjecture..


the following constants seem to be involved
./source/configuration:MINIMUM_DISK_SIZE=17
./source/configuration:TOTAL_MINIMUM_DISK_SIZE=50

If i'm right, reducing the first one might help you out
running 'service plc start bootmanager' should be all that's needed to ship the new constants to the node...

hope this helps
