We just experienced an error with the BOINC filesystem. As a result, the operating system re-mounted it in read-only mounted. We are now in the process of taking it offline and running an fsck on the filesystem. While that runs BOINC will be offline and not able to send or receive files.

The fsck is likely to take many hours to run.

We have modified the server to return a 503 error with a one hour retry for all attempts to download files.

The fsck is likely to take a long while (many hours). We are still in phase 1 of fsck (out of 5).

We have brought the filesystem online but we aren't sure what condition it is in. Instead of making it available, we have made it read-only and we are copying the data to our new filesystem that we were in the process of creating. The copy is now occurring but it will still be a number of hours to be available.

Copy is 14% complete. I will update this count periodically.

32.3% copied.
We have two sets of copies running. One for the workunit input files (download files) and one for the result files (upload). The upload is running faster than the download. As a result, we might be able to bring the uploads online before the downloads are available. |

Uploads are back online and handling the surge easily.
Overall copying is at 61.2%. We are watching to see how fast this progresses now that the upload copies are done. |
