VMDK Troubleshooting

Symptom Possible Cause
ESXi host registration fails ESXi host registration may fail with “No usable version of libssl was found” error on RHEL9 and its derivatives.

Cause: The library that PowerShell depends on is not installed on the system.

Action: Install the package compat-openssl11 provided by the OS.
Mount point is not included in the selection when creating resources Possible causes are as follows:
  • PowerShell/PowerCLI is not installed
  • An ESXi host is not registered
  • disk.enableUUID parameter is not set
  • The virtual hard disk is on a datastore that is not shared
  • SCSI controller sharing is configured as “virtual” or “physical”

Error details are recorded in /var/log/lifekeeper.log. Check the log and review the settings.
It takes longer to bring the VMDK resource in service Cause: The processing performed during bringing the resource in service takes more time in proportion to the number of virtual machines running on the ESXi host.

Action: A fundamental fix is under consideration for a future release. As an immediate workaround for this issue, please consider the following:
  • Reduce the number of VMDK resources
    Since the process is performed for each VMDK resource, the time required for the process increases in proportion to the number of VMDK resources. If multiple partitions or file systems are required for a single resource hierarchy, create multiple partitions or file systems on a single VMDK resource rather than using multiple VMDK resources.
  • If ESXi hosts that are not related to the cluster node are registered with the VMDK resource, unregister them.
