Greetings,

I need to remove 3 datastores. One has an HA folder in it with 'host-33-hb, host-33-poweron, host-10-hb, and host-10-poweron'. The other two have an HA folder but it only contains a 'protectedlist' file.

How should I remove these datastores since they contain these HA files?

Thanks a lot.

HA requires a minimum of 2 datastores to function. Edit cluster settings and then ensure that you select another set of datastores so that they can be used as "Heartbeat Datastores" and these may be removed.

You will also need to remove or Stop the FDM Agents on each Host, because there will be locks on files on the datastores.

thanks Arun. I have a few other datastores available for HA.

May I do this to the hosts during production hours? I do have ten or so VMs running on these hosts, on another storage device than the one I am removing of course.

I found this

http://arritdor.e-wilkin.com/2012/03/removing-vmfs-datastore.html

which I believe addresses my issue with screenshots and directions. Does it look correct?

Thanks again

thanks Andrew. I looked into that and found this

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2013249

do you have directions you can quickly share on how to properly do what you stated?

thanks again

Yes, that looks correct, but you may get issues

with

1. HA Agent (FDM)
2. Storage I/O control!

if it fails to unmount or delete the issues will be 1 or 2, or both!

Well, you can put the host in maintenance mode, remove them from the cluster and their entries will be removed from the heartbeat datastore respectively.

that's hot to stop the FDM Agents.

Arun - I need them to stay live if possible during this.

Andrew - I am looking into stopping the agents on each host, not the service. Also, Storage I/O is not configfured, so hopefully only issue 1 may arise, but I am looking into stopping the agent so it shouldn't.

thank you both. any info on stopping the agent on each host is appreciated. Thought this was going to be a simple process - then I found HA -poweron and -hb. Ugh.

The FDM agent is the one which initiates the communication. Stopping the FDM service will stop the HA agent. Check the /etc/init.d path for FDM service.

thanks Arun. Still worried about failover attempts if I stop the service.

Can I just disable HA on the cluster and then re-enable after removing the datastores? Don't laugh at that question ;-)

If you do that, it will re-configure HA all over again, although that would surely help.

Stopping HA Agent (FDM) Agent will not do anything, or affect VMs!

VMware HA is troublesome enough we have to stop weekly for clients!

1. Disable HA
2. Try unmount datastore (if it gives an error)
3. Stop FDM Agent.

That may be a good method. I'm adding a new host, moving vm's to it, and would like it to be master anyway.

Can I disable  / re-enable without issue during production hours?
Thanks.

Yes, you can disable/re-enable without issues.

But we would advise all good Service Practioners in the IT Service Industry, to always completed changes out of core hours.

I was thinking that myself and decided to hold out until this tonight or this weekend.

Thanks
