ORBIT-USER: Imaging Entire Grid ???

[Ivan Seskar]

Hi Shivesh,

Unfortunately what you are observing are deteriorating power supplies
(or to be more specific problem with standby power);  there is not much
we can do about it until May 20th when we are supposed to get first
batch of replacement power supplies (manufacturer acknowledged the
problem and agreed to ship us new ones). Now how long it will take to
replace all of them is something we can't estimate at the moment; we
will start with the nodes with dead power supplies (red ones one the
status page) and slowly move to ones that are flaky (hint for the Orbit
users who are within driving distance: any help will be greatly
appreciated and will most certainly speed up replacement). Until then,
best advice we can offer is to try to build the list of reliable nodes
(i.e. ones that image properly) and restrict your experiments to that
subset. Towards that goal, how about if everybody starts reporting nodes
issues at:

Ivan.

Subject: ORBIT-USER: Imaging Entire Grid ???

Hi,

I had a query regarding imaging the entire grid. Probably people who
work on a lot of nodes might have some idea ..

Whenever I try imaging the entire grid, on average only an 100 ~ 150
nodes seem to get imaged. I also shut down all the nodes before running
imageNodes4 

Does anyone have some kind of tweak (like some sequence to follow) when
imaging the entire grid which might help in getting more nodes imaged.
The other problem is that which so many nodes not actually being imaged,
it is very difficult to make out which nodes have been imaged and which
nodes have not been imaged. 

(I land up spending the better half of my slot finding nodes which
actually have booted in the correct image :( )

Any suggestions would be greatly appreciated.

Thanks !

Shivesh
