Server reboot - happening now
 
I'm about to reboot the Primenet server to make sure updates are installed. The ransomware outbreak going on today had me spooked and even though the server is firewalled these things make me nervous when the server hasn't been updated in a couple months.

As usual I'll say it'll only take 10 minutes but it will really take 20. So I'm saying it'll take 20 minutes (which means it might take 30?) :smile:

EDIT: And, back online after just 15 minutes or so. All done.

Primenet reboot coming up
 
I need to do some offline maintenance of Primenet... I did a little SQL shuffling of files and now I need to shut it down and make some changes on the virtualization layer.

I'm hoping it'll just be a quick process, maybe 10 minutes downtime max, but I can't really say how long one of the jobs will take.

Sorry for the interruption, but we'll have it back up and going before you know it.

EDIT: It finished pretty quick... back up and running.

Server maintenance - happening now
 
The Primenet server is going offline right now for about 30-60 minutes.

The plan is to make a clone of the system to create a testbed for work on PRP handling code (and we can also, in the future, use it for other system upgrades where we don't want to break the live system accidentally).

I'm not sure how long it'll take to make copies of the virtual drives so I can't be more specific... hopefully faster than an hour.

Back online... enjoy. :smile:

Maintenance starting soon
 
I'll be performing some server maintenance soon... a few minor updates but the big one will be updating SQL which will take longer.

I'm planning a downtime of 30-60 minutes but hopefully it'll be much less. Weekends are the time for doing such things. :smile:

Starting at approx 18:30 UTC (~ 5 minutes from now)

All done. I took a bit over an hour, but with a couple periods of uptime in between. Good to go.

Quick offline maintenance
 
The SQL upgrade revealed some horribly fragmented indexes... took the server offline real quick to rebuild a few that were slowing things down. Should only be a few minutes (knock on wood).

This would explain why I'm experiencing [CODE]Fatal error: Maximum execution time of 300 seconds exceeded in C:\inetpub\www\report_exponent\default.php on line 275[/CODE] and/or [CODE]500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.[/CODE] while searching for a single exponent. Hope it's transitory...

Yes, checking the exponent status on a single exponent can take a minute or more. Even if "Show full details" is turned off, it can take up to ten seconds.

Seems like some database indexes are not complete.

Yeah, I'm running into some horrible query plans. The log file also filled up overnight which was... unexpected. Probably my fault because of all the stuff I'd done and wasn't paying attention to it. Woke up to "out of space"... bleagh.

Fixed, and now I can troubleshoot the poor queries. :smile: To be honest, it actually seemed a little better because I nuked the cached query plans while I was at it. Maybe it got its head out of its butt. LOL

The [URL="https://mersenne.org/assignments/"]Active Assignments page[/URL] is empty (no assignments listed).

Exponent Status is still mostly much slower than before.
