The final big stage of the database merge started this morning, which is why the assimilators and splitters are off. Basically, we are now merging the final bits of data that were collected in the last month (since we started the merge). This should take a couple of days - hopefully we have enough work to send to last that long.
Over the long weekend we had a couple of connectivity issues. Both the upload and download servers have some kind of automounter problem where, under heavy load, they suddenly lose a random subset of their mounts. When this happens they still function but in a somewhat degraded mode, and eventually need to be rebooted. We also still have that feeder bug which clogs its shared memory segment so it is unable to cache enough work to send out. Both of these problems are being diagnosed. There are also continuing issues with the lab firewall/routers which is being handled by the lab administrators. Things are much better now in general, but there may be a day or two of the usual "catch up".
On the plus side, since we turned off the classic data server, we freed up one of our precious few Cogent IP addresses. So we are working toward moving the scheduler onto our private Cogent link, which will keep the bandwidth off the lab routers and therefore protected from those problems. |
