Looking in /var/log/mythor/init_mythor_2017_09_12_14_00_09.log, I see the following error message:

ERROR: DFS cluster topology for 'mythor', does not match existing DFS group layout for group 'mythor'

How do I correct this problem?

Fixed problem. I had /var/lib/HPCCSystems as a symbolic link which pointed to another directory. I did the following to fix the problem:
Code: Select all
sudo /opt/HPCCSystems/sbin/hpcc-run.sh -a hpcc-init stop
sudo /opt/HPCCSystems/sbin/hpcc-run.sh -a dafilesrv stop
sudo rm /var/lib/HPCCSystems
sudo mkdir /var/lib/HPCCSystems
sudo chown hpcc:hpcc /var/lib/HPCCSystems
sudo /opt/HPCCSystems/sbin/hpcc-run.sh -a hpcc-init start

My last post said I had fixed the problem. But, the fix was removing contents of /var/lib/HPCCSystem. But, I really don't want to do that.

I get this error after starting the cluster's instances on AWS. Everytime. I can get rid of the problem by doing:
Code: Select all
sudo rm -r /var/lib/HPCCSystems/*
which deletes the contents of /var/lib/HPCCSystems.

But, that isn't the best solution because I need data that is stored there.

Anyone have any ideas???

It would help if I knew what the error message is telling me:
Code: Select all
DFS cluster topology for 'mythor', does not match existing DFS group layout for group


What I think it is telling me is that there is something in the Topology attribute of my environment.xml file that doesn't match with something about 'mythor' that is stored someplace on /var/lib/HPCCSystems.
