V18>V20 Upgrade - How long before I give up

[Lee Cramman]

I've set aside some time today for the upgrade and set it away.

I don't have a failure notification, but the upgrade has been running for over an hour. Observability on the GCE instance has gone a bit... odd..

Performance does not seem to be being reliably updated / relayed back to GCE from the instance. For instance the disk throughput has dropped back to about a third of its highest level now but consistently reports exactly the same speed.and has done for about 20 minutes - and I don't mean reports a similar speed, I mean exactly the same (5.02Mb/s).

Logging appears to have stopped.

CPU usage is <20% and network traffic is virtually zero.

How long do I give it before assuming this upgrade has died? Are there any reliable methods for checking if the upgrade is still in progress?

Did you check the system requirements? What kind of system do you use for pbx?

 

[Lee Cramman]

Within requirements - not expecting any issues. GCE instance with 2 VCPUs, 2Gb RAM and no third party stuff.

 

[Lee Cramman]

Time to give up and revert to snapshot... this has all the hallmarks of a hard fail.

 

[bitn2]

Than its to long... normaly the upgrade should not take more than 20-30 minutes. You could check by ssh if there is something still working

 

[Lee Cramman]

SSH won't connect even though GCE says instance still running - I think that says it all.

Looks like it crashed harder than Windows 95.

Not an easy one to troubleshoot (no failure logs) so I suspect a restore from backup out of hours is the way to go.

I am curious how the revert went. We have a pretty complex setup, and I would love to take a checkpoint, update and if there are issues revert. Are there issues with the 3cx license if you update to v20 and revert?

In those cases, it will be best to get SSH before you start and then tail -f the file that will show you the upgrade process, it should be in /var/lib/3cxpbx file called debian10to12.log

It went fine - no issues following revert from snapshot.

edit: Although it meant I lost the failed install log, I couldn't be bothered mounting the vdisk and messing about.

Thanks @OlegR_3CX, I'll give that a go if I decide to try again.

However, I'm tempted to redo this as a restore from backup to a clean install to head off any issues.

You are welcome. That log file will give you a heads-up to what is the cause of the upgrade not going though.
Check this guide before the upgrade, too.
