[Cause analysis]

Check the CNA logs. It is found that the pvsvm information of the id disk on the CNA fails to be set when the InsertRagionInfo task is executed.

The directory creation failure is rare. Unless the disk space is used up or the file link on the data store is full, the directory cannot be created if the I/O pressure is too high.

The disk I/O pressure is high due to the batch delivery. At the same time, 10 concurrent writing operations are being performed at the same time.

The iostat command can also be used to check the disk performance. Therefore, it is suspected that the problem is caused by the concurrent disk performance. As a result, the system command fails to be executed.

[Solution]

1. Do not provision VMs in batches.


2. If some VMs fail to be provisioned, provision VMs again.


3. VMs are provisioned in small batches and in multiple batches.
