flexgroup-msid missing in REST API?

[PoINT_dg]

Hi,

REST API returns "msid" for each reported volume, but how do I get the "flexgroup-msid" which can be displayed via CLI? My goal is to find the flexgroup volume for a given "flexgroup-msid" and I would expect that the "flexgroup-msid" is the same as the "msid" of the flexgroup itself, but this seems not to be the case. 

Thanks,

dg.

Hi,

I did some more testing with ONTAP 9.14.1 simulator and found that this seems to be an issue in REST API: The "msid" returned for flexgroup volumes is the one of the first constituent and not that of the flexgroup itself. My above expectation is correct, that "msid" and "flexgroup-msid" are the same for flexgroup volumes which can be confirmed via CLI:

cluster::volume*> show -fields flexgroup-msid, msid -volume-style-extended flexgroup
vserver volume msid       flexgroup-msid
------- ------ ---------- --------------
svm0    flex1  2150247878 2150247878

But the msid returned by REST API for this same volume is 2150247879, which is the first constituent in my case:

    {
      "uuid": "387a6e6e-174c-11ef-8b43-000c2966c17d",
      "name": "flex1",
      "style": "flexgroup",
      "type": "rw",
      "msid": 2150247879,
      "_links": {
        "self": {
          "href": "/api/storage/volumes/387a6e6e-174c-11ef-8b43-000c2966c17d"
        }
      }
    }

The legacy ONTAPI returns correct information on the same system.

Can someone from NetApp confirm my observation or tell me where I am wrong?

More input from my side. This only happens when using SVM tunneling. The returned msid is incorrect:

curl -X GET "https://192.168.202.190/api/storage/volumes?fields=name,style,type,msid" -H "X-Dot-SVM-Name: svm0"
{
  "records": [
    {
    },
    {
      "uuid": "387a6e6e-174c-11ef-8b43-000c2966c17d",
      "name": "flex1",
      "style": "flexgroup",
      "type": "rw",
      "msid": 2150247879,
      "_links": {
        "self": {
          "href": "/api/storage/volumes/387a6e6e-174c-11ef-8b43-000c2966c17d"
        }
      }
    }
  ],
  "num_records": 2,
  "_links": {
    "self": {
      "href": "/api/storage/volumes?fields=name,style,type,msid"
    }
  }
}

 Without tunneling, the msid is correct:

curl -X GET "https://192.168.202.190/api/storage/volumes?fields=name,style,type,msid"
{
  "records": [
    {
    },
    {
      "uuid": "387a6e6e-174c-11ef-8b43-000c2966c17d",
      "name": "flex1",
      "style": "flexgroup",
      "type": "rw",
      "msid": 2150247878,
      "_links": {
        "self": {
          "href": "/api/storage/volumes/387a6e6e-174c-11ef-8b43-000c2966c17d"
        }
      }
    }
  ],
  "num_records": 2,
  "_links": {
    "self": {
      "href": "/api/storage/volumes?fields=name,style,type,msid"
    }
  }
}

Additionally, there seems to be some caching causing inconsistent results.
