Message 72259 - Posted: 27 Mar 2022, 19:35:06 UTC

Hey Everyone,

I will be turning off the mysql DB for the server at midnight UTC (8PM EDT) for 12 hours. Last time I kept some processes running, but turned off the WU generators in order to give things time to catch up from the drive failure (they are currently still off). I don't think that the server finished rebuilding then, so I will be turning all MW processes completely off for 12 hours, and then hopefully by the time I turn things back on again, the drive will have rebuilt.

If you only tune in to the BOINC notices, apologies for the massive drops in RAC lately. These are related to a hard drive failure that we are still in the process of recovering from.

Thanks for your patience. I know that this has been very frustrating for all of you, and it has been frustrating for me as well.

Best,
Tom

Hi Tom,

Thank you for this Info.

As my RAID6 rebuilt the last Time is took 4 Weeks.
My Setup was 8x8TB Drives.

Next Time I took all my Data off the Storage, exchanged the Drive and Intialized from Scratch and took my Data back on the Storage.
This took only 2 Days and was a little quicker ;-)

I hope things will come back running again...
<crossedfingers>

Kind regards

Good to know Atratus. I was under the impression that it wouldn't take that long, but that does reassure me that the problems we are experiencing are due to the RAID rebuild and not due to other server problems (knock on wood).

I've just been notified that the server rebuild has completed, so hopefully we can get things running as per normal soon! I'll be paying attention to things throughout the day in order to fix any weirdness that comes along.

The tasks ready to report still are waiting.

I'm not surprised things are not running at full speed, that is going to take some time. Seti@Home when it was active had weekly scheduled downtime for project/server maintenance, the recovery time was lengthy.

Huh, it looks like the feeder is running on our end, at least if you check the status page (https://milkyway.cs.rpi.edu/milkyway/server_status.php).

Let me try restarting all the processes and see if that helps at all. Otherwise, I might just restart the machine.

As of this time, Feeder is not running per Notices tab.

That might have been because I was rebooting the server and bringing things back up. When I look at the server status page, it is up now.

Tom,

It is still saying the feeder is not running, and it requests a delay of 400 seconds rather than the usual 91 seconds. (I don't now whether that is specific to that feeder error state or not...)

The status page I see is nearly 24 hours out of date - the numbers seem unchanged and the timestamp line at the bottom says
Task data as of 27 Mar 2022, 18:54:47 UTC
If you're seeing something different at that URL there's something amiss!

Any clues in the various logs??? I don't envy you having to try to sort this out...

Good luck - Al

@ Tom:

the up- and download servers were not stopped - they were green, while the other were red (as far as I saw).

I'm still getting server errorr: feeder not running.

the project status page ist dated from the 27.

ready to report task still not beeing called home

unable to get tasks

why weren't the up- and download servers restarted?

There might e a differential behaviour between a "re-start" and "cold-Start" - as in many situations this is a problem.
Maybe a complete power down inclusive pulling the wall-socket for 10 minutes would do it?

cheers

The download and upload servers don't usually get restarted when I restart all of the milkyway processes. However, I did restart the server, so they would have been restarted. The up and download servers come up automatically when the server turns on (which is why they were green), but the other processes have to be started manually (which is why they were red). I don't have physical access to the server, so I can't power cycle the machine.

So, just to confirm, you are not able to contact the server from your client? Does it say that the feeder is down, or what error does it report?

Okay, I am going to try restarting all the processes again. I'll let you know when I am done, and we can check if it is working then. If not, I can reboot the whole system again.

If that doesn't work, then there's a problem somewhere that's more serious.
