Re: [Development] CI going down for update

Hi

Let me recap what we did last weekend.


  *   The Coin storage now has more storage space available. This should mean 
less rebooting the system for cleanup.
  *   We also noticed a VMware teak that increases the I/O from the storage. 
This could potentially make Coin more stable as the bandwidth doesn’t run out.
  *   We now have LVM installed, so further expansion of the storage is easier 
now.

Because we installed LVM, we had to redo the partitions. This required us to 
move data about a lot. We could have just deleted the logs and artifacts and 
let Coin rebuild them (we would have gotten the system up already on Friday 
evening), but by copying over all the data from a backup we enabled Coin to 
resume like nothing had happened (didn’t need to rebuild all the existing 
artifacts). It also enabled all the current logs to be visible for our company 
internal users that read the data straight from Coin instead of 
testresults.qt.io where they are published. With all the flaky autotests we 
had, we might have ended up trying to recover from lost artifacts until 
Saturday morning anyway. So the delay wasn’t bad if we think about it that way 😊

On an unrelated note. We’ve reverted some of the build hosts to Ubuntu 16.04 as 
the underlying platform. It looks like it’s just as stable if not more stable 
than the 17.xx ones. At least as of yet, not a single one has crashed! If this 
continues, this is _very_ good news for the CI. It will knock down a very 
annoying problem where the hosts that’s running all the virtual machines kept 
crashing and failing all the builds. Let’s hope this trend continues.

Happy building!

Hi



We have to do things the hard way, meaning copying over a lot of stuff instead 
of just converting stuff. No unexpected things have poped up during the hard 
way however, but the copy phase takes a lot of time. ETA (or nothing really 
arrives now… so EToC): in a few hours.

Hi



We’ll take the CI down for update for a short while. The web page won’t work at 
all during that time, since we’ll close the whole server.



Thanks for your patience.
