If it is your cdot environment , you have to try " vol modify " command with vserver name as your node name and use option "-policy " to export it.
Policy option could be your "default" or user create policy . Once you export it through that policy, try mounting it on the servers mentioned in the rule of export policy.
First, try this command to check the export policy value ( vol show -vserver NODENAME -volume vol0 ), whiich should be something like this .
Volume Name: vol0
Aggregate Name: aggr_root_nodename_01
Volume Size: 442.4GB
Volume Data Set ID: -
Volume Master Data Set ID: -
Volume State: online
Volume Type: RW
Volume Style: flex
Is Cluster-Mode Volume: false
Is Constituent Volume: false
Export Policy: -
User ID: -
Group ID: -
Security Style: -
After this, decide if you want to export it to default export policy or user defined policy . Use that to bind it to the "vol0"
Let me know your result

You do not mount vol0 via NFS in cDOT. In fact, it's not possible at all.
Vol0 in cDOT is the "mroot" volume. That collects system logs, contains the replicated database, etc.
What is the use case for needing to access the root volume?

I am running cDOT simulator in local system. The vol0 is getting full daily, I dont have any storage space to increase volume size and I have disabled Autosupport, Audit log.. etc.. I am bored of deleting indivudual files manually in /etc/log. Instead I want to mount the vol0 of node in any unix host and delete the logs regularly by running script.

Mounting vol0 is not advisable, but there is a possibly to mount it.
I understand that we have all critical files in there, but still if you need it you can mount it using the commands that I gave.

It's not supported on 7-mode style volumes:
::*> vol modify -vserver node1 -volume vol0 -policy default
Error: command failed: This operation is not supported on 7-mode volume "vol0".
Perhaps in engineering builds it is, but not in customer-facing builds.
