Hi,
Am in the process of unmounting a number of datastores from vcsa 6.0 (all VMs migrated from them) but this is failing for a small number of hosts due to "File system is busy" message.
I am going to follow the steps shown in this link VMware Knowledge Base but not sure what is the impact on the hosts if the dumpfiles are removed? (Will it automatically create a new one on a new random datastore next time)
How can I check if the datastore is used as an HA heartbeat as when I checked the HA configuration the "Use datastores from the specified list and complement automatically if needed" but none of the datastores is ticked. Would this prevent me from un-mounting the datastore or would HA pick up another datastore automatically without any impact?
The datastore is not part of a Datastore Cluster and Storage I/O Control is disabled for the datastore, let me know if you have other suggestions as suspect that there are files on the datastore that are still actively used/locked by one or more ESXi hosts. Want to avoid rebooting the hosts which cannot have the datastore unmounted from.
Thanks
