Get Volumes Rest API not returning all volumes

kramar — Wed, 04 Jun 2025 10:11:21 GMT

We are facing one strange issue. For some reason, we are not getting volume’s details through REST API.

For example, we have these 2 volumes in the cluster running 9.7P10:

us01cmsgrid::> vol show VG_ARCHIVE*

Vserver Volume Aggregate State Type Size Available Used%

--------- ------------ ------------ ---------- ---- ---------- ---------- -----

us01cmsgridvs1 VG_ARCHIVE - online RW 100TB 15.74TB 84%

us01cmsgridvs1 VG_ARCHIVE2 - online RW 100TB 69.79TB 30%

2 entries were displayed.

They are set up identically.

But when we make API call, only VG_ARCHIVE2 is showing up:

$ curl --location --request GET 'https://us01cmsgrid/api/storage/volumes' -k | grep -i "VG_ARCHIVE"

"name": "VG_ARCHIVE2",

$ curl --location --request GET 'https://us01cmsgrid/api/storage/volumes?name=VG*' -k

{

"records": [

{

"uuid": "63f910f4-e7db-11ea-badf-d039ea14ccfe",

"name": "VG_ARCHIVE2",

"_links": {

"self": {

"href": "/api/storage/volumes/63f910f4-e7db-11ea-badf-d039ea14ccfe"

}

"num_records": 1,

"_links": {

"self": {

"href": "/api/storage/volumes?name=VG*"

}

Am I missing something?

It might be having problems with the underscore "_" in the volume name. I did a few tests and depending on where I add the "*" I get different results - though it's either no volumes or all of them. Why you would get only 1 volume is still a bit odd. I found that if I add the wildcard on both sides of the underscore it works (ie. VG*_*). Still - you'd think it would 'just work' 🤔 The NetappPub Slack channel (netapppub.slack.com #api) would be a good place to ask about this one.

Hi,

Thanks but it still did not work even when I used "VG*_*". Also, we are calling "https://clustername/api/storage/volumes" in our scripts to get output for all volumes at once. We are trying to understand why that specific volume is not showing up there.

Do you get the same result when using Swagger?

Also, I've posted the question in the slack api channel.
