can not clone or create a virtual machine to vsandatastore

[robinni]

Hi, All

     I try to clone a virtual machine to vsandatastore. But I see the follow error:

     -->The policy requires 2 replicas with 1 disks each with 0 bytes free each. Only found 0 such disks.

      -->Failed to create object:

   The hardware configuration is as follows:

    I/O Controller :LSI SAS9271-8i

    HDD: ST91000640SS

    SSD:Intel SSSDSC2BA400G3

     10GE: Intel 82599

   When I create a virtual machine or create  a file to vsandatestore on web client. I also see the same error.

  Could some one give me some suggestions? I don't know how to resolve this problem.

    Thanks!

And you have a minimum of 3 hosts in your cluster?

Hi depping

          Yes. There are 3 ESXi hosts in my cluster.

          When can not clone a VM to the vsanDatastore. I am thinking if I  can create a file or document to the vsanDatastore?

          I have try to test if I can create a file or document to the vsanDatastore in vSphere web client. But popup a windows and show the same information.

          -->The policy requires 2 replicas with 1 disks each with 0 bytes free each. Only found 0 such disks.

           -->Failed to create object:

        (1) After that, I try to use "/usr/lib/vmware/osfs/bin/osfs-mkdir" command to create a document in vsanDatastore. It is success. I don't know why the vsanDatastore can not be created a file or document  in vSphere web client.

          (2) I can not use "mkdir " command to create a document in vsanDatastore. But after I use ""/usr/lib/vmware/osfs/bin/osfs-mkdir" command to create a document "test" in vsanDatastore. Now I can use "mkdir" to create a document in /vmfs/volumes/vsanDatastore/test/ path. I was confuse.

Not sure why you are runnning those commands?

> The policy requires 2 replicas with 1 disks each with 0 bytes free each. Only found 0 such disks

This means that all the three nodes in the cluster are not participating in Storage. check whether all 3 nodes have atleast 1 diskgroup and contributing in storage

default vsan policy is 1 failure to tolerate which creates two replicas. so you can either make sure all 3 nodes have atleast 1 diskgroup or create a vm storage policy overriding the defaults

Thanks,
