unable to start cloudera-scm-server-db.service on Linux in Azure

Question

hiI created a CentOS 7.7 Linux machine (but also happens with RHEL 7.4) on Azure.I installed the cloudera-manager RPM packages via yumWhen i try to start the cloudera-scm-server-db service I get "permission denied" on /var/lib/cloudera-scm-server-db/dataI added -x flag to the /usr/share/cmf/bin/initialize_embedded_db.sh, and added the "strace" command before the initdb command.I see that the command is running as cloudera-scm user (in the /var/log/messages file)and Is see in the strace output, that it fails on "chmod("/var/lib/cloudera-scm-server-db/data", 0700) = -1 EACCES (Permission denied)"When I run the command from Linux CLI as user cloudera-scm it runs OK.Does the Linux behave differently on Azure (i.e. more security features)I don't think it relates to firewallI see in the /var/log/messages the following messages:Oct 22 12:53:14 cdh-doxi-1 systemd: Created slice User Slice of cloudera-scm.Oct 22 12:53:14 cdh-doxi-1 systemd: Started Session c1 of user cloudera-scm.Oct 22 12:53:16 cdh-doxi-1 systemd: Removed slice User Slice of cloudera-scm.could this slices are doing the damage?I see it relates to cgroups (but I'm not sure what it actually means) - can I turn this off somewhere?do i need to reinstall the Linux with different flags?TIADoron

Can you verify the proper ownership of the cloudera-scm-server-db folder by running below commands :

chown -R cloudera-scm:cloudera-scm /var/lib/cloudera-scm-server-db/
chmod 700 /var/lib/cloudera-scm-server-db/
chmod 700 /var/lib/cloudera-scm-server-db/data
service cloudera-scm-server-db start

Also verify the selinux status by running

sestatus
