YooHoo!

I have a problem - a work computer died. I only saved the folder "projects" (I guess this was not enough)...

Now I have a fresh installation of BOINC, restored the projects folder, and patched manually the computer ID in files where I found it. But now I only can get new work units, but not the one that I'm supposed to finish.

Is there some way to fix this? Like 're-download work units' or some way to 'move work units to restart on another computer'? Or did I mess up too bad and I just have to let the work units expire?

Thanks in advance,
Mordrak

Do you still have, not just the projects folder, but the whole upper level BOINC Data folder? If you still have that, with all the sub-folders, you have a chance.

Set 'No new tasks' on your temporary re-installation, for all projects. Wait until all the replacement tasks finish, and allow them time to report (or you can hurry that up by manually updating a project, even if it's in the middle of a backoff).

Move your whole new data folder structure somewhere safe - it may be easier to stick with that, if the subsequent steps go pear-shaped.

Bring back your original data folder, but don't start BOINC just yet.

You mention that you had restored you computer IDs. You also need to make one more change.

In client_state.xml, in each <project> section, you will find the <hostid> - the original one. A couple of lines above that, you'll find <rpc_seqno>. Go to that project's website, look at your computer's detail page for that project, and see "Number of times client has contacted server". Set the <rpc_seqno> to one more than the website number. For example, this machine has contacted SETI 187547 times, and client_state has <rpc_seqno>187548</rpc_seqno>.

Be careful when editing client state.xml - don't change anything else. It's an important and fragile file.

Best of luck.

Thanks for your reply -- the whole data folder is no longer available unfortunately. Just the project folder :-(

The rpc_seqno is now +1 to what the web page shows, but it doesn't try to re-download anything or show anything in the tasks-tab.

I guess the only thing I can do is forget about that machine and let the work packages all expire... Next time (I hope there won't be a next time) I'll backup everything.

Kind regards,
Mordrak

And depending on how different the architecture of the new machine is from the dead one it may not have worked anyway.
