  • Virtual machine (VM) fails to start
  • VM files fail to delete on datastore
  • Virtual desktop infrastructure (VDI) Machine BSOD
  • In the vmkernel.log, you see entries similar to:

  • In the vmware.log, you see similar to:

Environment

VMware vSphere ESXi 6.0

Cause

Data corruption during reclaim disk space of linked clone with sesparse vmdk.

Resolution



Workaround:
To workaround this issue for VDI VMs in ESXi 6.0, use any of the below workarounds

Workaround 1

Check and attempt to repair the disk.

  1. SSH to the ESXi host where the VM resides
  2. Check the file location:
vmkfstools -x check /vmfs/volumes/<datastorepath>/<vm name>/<vm name main base disk>.vmdk
  1. Repair the file path:
vmkfstools -x repair /vmfs/volumes/<datastorepath>/<vm name>/<vm name main base disk>.vmdk



Workaround 2

Disable ATS heartbeat for all hosts.

Refer the article for Disabling ATS heartbeat, ESXi host loses connectivity to a VMFS3 and VMFS5 datastore (2113956)

Workaround 3
Reclaim Disk Space in Horizon
