Upgraded an Existing Server to 1.4.4 and Now Interface is Very Slow and Chromium Images are not working
-
@rstockham23 Lets try this, go to: FOG Configuration->FOG Settings->FOG Client->FOG_CLIENT_CHECKIN_TIME note the value and then set the value to 900. Wait what ever your checkin interval was and see if response is better.
-
@george1421 It was set to 30. I changed it to 900.
-
@rstockham23 OK so every 30 seconds all 500 systems “ping” the fog server looking for any new instructions. So wait 5 minutes and see what your load is like.
Now understand we’ve set the check in interval to 15 minutes. That means if you schedule a snapin deployment to these computers, It will take up to 15 minutes for the target computer to get the job.
-
@george1421 @Wayne-Workman Setting the Client Check In to 900 has definitely helped the performance. Interfaces are acting more normal now and cpu usage has dropped significantly. Strange that it didn’t have that problem before, but does now, but glad to see it working better.
Still no luck with the Chromium image though. I thought since performance was fixed, I’d go ahead and upload a new image again and then try to download it to another laptop. Again, upload shows that it’s successful, but when I go to deploy it on another computer, I’m getting this error: https://photos.app.goo.gl/I75ORDRoDZqf24OU2

@rstockham23 To me it sounds like the image doesn’t exist on the nodes at /images/2018CloudReady.
Can you verify that the storage nodes you require to have this image actually have it?
-
@tom-elliott Yes, I looked on the Node in the /images/2018CloudReady folder and it was filled with files that seemed similar to other images on the node. I just blew it away and trying it all from scratch again, now that our performance issues are better and will report back.

@rstockham23 I really dislike chasing two issues in the same thread, but back on the performance side.
Can you describe your fog server a bit?
- What OS is it running
- Is it virtual or physical
- Number of vCPUs/Cores
- What is your disk subsystem (raid, single hdd disk, ssd?)
-
@george1421 I do apologize for chasing multiple issues. I guess my original issue was just one issue that things broke after upgrading to a newer version, but it was definitely multiple things.
Fog Server is a VM running Ubuntu 16.04 I have 2 CPU’s dedicated to it and it’s a RAID configuration on the master VM Server which is a Dell Poweredge 2950 if I’m not mistaken.
I also have 8GB of Ram dedicated to it.
-
@tom-elliott Tried another Chromium image from scratch and still not working. However I also tried a new test Windows 10 image just to see what it would do and it worked fine. So the general process of imaging from creating to deployment is working, but not with any of the Chromium images.
-
@rstockham23 Good, I think you guys already found and partly fixed the performance issue. To keep things a bit sorted I’d ask you to open a new thread for the UUID issue as well. We’ll move the related posts to that new thread then. I’ll likely have a bit of time to look into this problem on the weekend.
