I am replacing one of my crunchers with another machine (my new 32 core Big32). I tried to release all of my 300 tasks on KeplerBox by doing a project reset of SETI. This dumped all my tasks (I see 0 tasks on it now when I bring it up with no networking to prevent new tasks being downloaded). Yet, under my account, view computers, it says 300 tasks still in progress. Is that just a fluke of BOINC, or are my wingmen screwed until those tasks time out?

They are now "ghosts" and will have to time out. In future, you can abort the tasks then update the project and then they will be immediately reassigned.

(Edit: Ensure "No new tasks" is on when this is done of course!)

A lesson learned the hard way :-(

There is one way of moving a machine from one disk to another, but it may not have worked in your case.
Suspend all projects
Copy the "old" BOINC data folder onto a usb drive
Install BOINC on our new machine but do not let it run
Copy the BOINC data folder from the USB drive over the data folder on the "new" machine.
Restart BOINC on the new machine, it may work, but if the changes between "old" and "new" are considered by BOINC to be sufficiently significant it probably won't.

The use of rabbits feet, crossed fingers etc. is probably an aid, but no guarantee...

It is worth noting that your "new" machine now has a full payload of 300 tasks in progress, so there is no point in trying to recuse those orphaned tasks, they will time out and be resent to other users.

From what I understand, if it's an option and time allows, just set it to NNT and let them process out, and when you are done, shuterdown and move to the next computer. If you'd like to keep the same machine number, you can try following Robs advice after they have all crunched and reported, and that way best case your machine lives on, worst case, you have to create a new ID.

We advise a slightly different sequence.

Suspend all projects
Copy the "old" BOINC data folder onto a usb drive
Copy the BOINC data folder from the USB drive over the data folder on the "new" machine.
Install BOINC on our new machine
Start BOINC on the new machine.

Like the machine I'm typing on:

Thanks all for your help. Too bad there's no way of fixing it now. I didn't care about the new machine having a different number, but I STILL screwed up.

Does that fit me for working on the next (first?) revision of you-know-what?
