Description

Error Message

The Restore job will fail with Error ; 

0xe00095a4 - Operation failed because the vCenter or ESX server reported a problem creating or accessing one or more necessary files

 

The beremote_AlwaysOnLog.log at the Media Server will record ;

[fsys\vmvcb] - VM_VCBPROXY_FS::CreateVirtualMachine: vmcCreateVirtualMachineEx reported: Insufficient disk space on datastore 'VMW_VOL_04'., <0X123>

Cause

As part of the Restore job, a check is made on the amount of free space available in the target location, to confirm whether the restore data will fit. The calculation used is based on the size of the complete VM server, not just the partial data that has been selected for restore.

Example:
You select to restore a single 500Gb VMDK disk from a VM guest server that has a total size of 2Tb (multiple disks). The Destination you are restoring to only has 1.5Tb space available

In this scenario, the restore will fail, even though there is enough space to store the single 500Gb disk.
You will need to have at least 2Tb of free space available on the Destination.

 

Resolution

Provide additional free space to the restore destination, so that there is enough space available to store the complete VM server the restore is for. 

Note:
Veritas recommends that you always have enough free space available to be able to restore the largest VM completely.
