AltocumulusDSC is not coming up for LTM VEs after initial setup
AltocumulusI have also run into this caveat. I am running 13.1.1.4 on VMware Workstation 15 on Fedora 29 Linux kernel 5.0.4
I have managed to resolve the problem with the following db variables on the each of cluster members:
tmsh modify /sys db tm.tcplargereceiveoffload value disable
tmsh modify /sys db tm.tcpsegmentationoffload value disable
To be sure, I had to go through devicegroup trust reset and reconfiguration of DSC. Now everything is fine.
It appears VMware has issues with offloading mechanisms. In 12.1.x everything was running fine.
NimbostratusKrystian - this is genius, thank you. Worked for me (Windows 10, VMWare Workstation 14, BIG-IP 13.1.3). I was seeing exactly the same messages Oleksandr mentioned and your fix solved the issue. I did not need to reset trust, just made your recommended changes and was able to sync straight away. Thanks again, I had been banging my head against a wall!!
Out of interest, if you are able to share how you came upon the solution, I would be interested to hear the story - I had no idea those db variables even existed and would never have known to look for them
