Issue/Introduction

Symptoms:
  • Cannot take a snapshot of the virtual machine
  • Taking a snapshot of the virtual machine fails
  • The vSphere Client, you see the error:

    Error occurred while saving "snapshot_name"


Cause

This issue occurs if there are any problems with the underlying datastore on which the snapshot is being stored. These datastores can either be NFS or VMFS. VMFS datastores are backed by LUNs accessed through FC/iSCSI/Local SCSI controllers. This error is reported if the ESXi host encounters any storage I/O errors while writing the snapshot to the datastore.

I/O to the datastores can fail for multiple reasons, such as:
  • Datastore has reached its maximum capacity.
  • I/Os timing out because the underlying storage is overloaded.
  • Storage connectivity issues between the ESXi host and storage arrays in case of FC.
  • Network connectivity issues between the ESXi host and storage in case of iSCSI and NFS.

Resolution

To resolve this issue, check these options:

If the issue persists even after trying these options, file a Support Request with VMware Support. For more information, see Filing a Support Request in Customer Connect (2006985).
