Upgrade from 1.5.7 to 1.5.8 issues
-
@george1421 While I agree and understand how it all works. I have found that we did get an increase in speed when we setup the aggregated adapter on the storage node. Even with just one client going. But perhaps that’s really just agreeing with your statements. As like on a highway if it was 1 lane, you often slowdown cause of the other slow drivers and perhaps I just opened up a metaphorical passing lane for fog images to go the full speed limit at. You do also have to consider all the switches it goes through and yada yada. And of course it’s all more complicated. Point being, I didn’t get a 2x boost when we aggregated the server link, but we did get a boost, so I wouldn’t deter anyone with the equipment capable of it from giving it a try.

After a test with the new init I am still having the issues of speed decrease. It is almost double what it used to take. My images being pushed out was around 2:30 minutes and now it is 4:17.
Ok, then we need to start looking at other things I suppose. Did you try going back to use the inits from 1.5.7 (only inits, not the kernel as a first try) as suggested by @george1421 yet? https://fogproject.org/binaries1.5.7.zip
What if there is something in your network that changed?
-
@Sebastian-Roth Nothing on the network has changed and I did try @george1421 suggestion as well. It was a 2 minute install/upgrade of 1.5.8 and the snapshot revert took about 2 minutes max. Sorry, I have been on vacation the last couple of days but I wanted to make sure and get back to you on those things.
-
@Chris-Whiteley So what’s the outcome of testing George’s suggestion? Sorry for nagging. Take your time…
-
@Sebastian-Roth it was the same as the new init
-
@Chris-Whiteley So that would leave us with an issue in the Linux kernel or FOG server. Kernel is easier to test. Leave the inits from 1.5.7 in place and grab the kernel binaries (
bzImage*) from the archive to use. See if it’s back to speed like this. -

-OR- something outside of FOG causing the delay.
-
@Sebastian-Roth I just tested with the old bzimage for 1.5.7 and the speed was much faster and what I am used to.
-
@Chris-Whiteley If you are testing the bzImage from 1.5.7 and 1.5.8 on different days, could you test the bzImage from 1.5.8 now? I’m just trying to rule out other variables, because what you’ve told us, should not be. I’m not saying it can’t happen, only its a bit strange in the same series (4.19.x)
-
@george1421 I am testing it now. I found the 1.5.8 binaries.
-
@Chris-Whiteley That was the 4.19.101 version.
But maybe now I’m confused. I’m trying to build a truth table and I thought we zeroed in on something
1.5.8:bzImage 4.19.101 1.5.8:init.xz == Slow (partclone 0.3.13)
1.5.8:bzImage 4.19.101 1.5.7:init.xz == Slow (partclone 0.3.13)
1.5.7:bzImage 4.19.65 1.5.7:init.xz == Fast (partclone 0.2.89)
1.5.8:bzImage 4.19.101 1.5.7:init.xz == ?? (partclone 0.2.89) -
@george1421 This is correct so far. This last test proved to be faster this time…hmmm…This has also been the most stable as far as not going from ridiculous speeds down to what it actually should be. Now it starts where it normally rests at.

Just as fast, or faster than last time?
Also this is why I wanted you to test the same day with the same set of circumstances. Just in case there was something in network land that was different than last week.
-
@george1421 Just as fast as when I had 1.5.7 and it was working. Both tests from normal SSD and NVMe worked as I think they should. How do I now get an output of what versions of things I have so that you guys can figure out what you need to?
-
@Chris-Whiteley well for bzImage that’s easy
file bzImagewill tell you the current version of bzImage.For init.xz its not as easy but not hard either. If we use md5sum utility we can get the fingerprint of init.xz file.
This is for 1.5.7
md5sum init.xz 913326f3317b577be3cb65a7bf332afb init.xzIf you have the chance, since something is different, can you test with the init.xz from 1.5.8? Its best to do all in one day if possible.
-
bzimage - 4.19.101
init.xz - 9133326 -
@george1421 just tested with the 1.5.8 init.xz and got the slowness again

Ok so what the developers (or myself) need to do is pluck out partclone from the 1.5.8 inits and install it in the 1.5.7 inits. This will point exactly to partclone.
The issue with 1.5.8 (not a problem just many things change) is that the system used to create the virtual hard drive (init.xz) was upgraded, this also upgraded a number of support modules inside the init.xz. So on the surface we don’t know if the latest version of gzip is doing this or partclone. At least in my head.
-
@george1421 Thanks for the update! Let me know what you guys find and if I can be of anymore help.
-
@Chris-Whiteley For now you have a path using the 1.5.7 inits. I might have time later tonight to unpack and repack the inits to copy over partclone. Once that is done we’ll have you test with the 1.5.7 inits with the patched in 0.3.13 partclone. Testing that will tell us about the next steps.
Thank you for your help til now to give us a clear picture of where the problem isn’t.
