we running vsphere essentials plus 6.5 with 3 hosts at build 8935087 and upgraded vcenter via webinterface on port 5480 to the latest one (6.5.0-23200).
the three hosts are in a cluster.
after successful upgrading the HA fails and i disabled it temporarily.
i tried several solutions like this:
disconnect/reconnect hosts
disable/enable ha
restart mgmt services on hosts
restart vcenter appliance
checked network settings of hosts
NOT DONE: restart host(s) / reinstall fdm service
similar problems described here:
vmware esxi - vSphere 6.5 HA agent cannot be correctly installed or configured - Server Fault
fdm logs checked, there are messages like this on all hosts:
>> error fdm[38F7940] [Originator@6876 sub=Cluster] [ClusterPersistence::DoFetchDataSync] Open of file /etc/opt/vmware/fdm/kvstore failed: No such file or directory
only on one host:
>> error fdm[3FB5B70] [Originator@6876 sub=Cluster opID=SWI-427c3c55] [ClusterManagerImpl::RemovePowerOffFile] Couldn't find datastore /vmfs/volumes/5XXXXX8 so file not removed
--> but the datastore is accessable within normal operations (ui and ssh)
any ideas,hints, solutions for this issue?
