Oracle Linux: Fail to Create Directory on Bucket Mount Using OCIFS

Applies to:   

Oracle Cloud Infrastructure

Oracle Linux - all versions

Symptoms 

Fail to create a directory on an OCI Bucket mounted using OCIFS 

$ sudo mount -t fuse.ocifs <bucket_name> /mnt -o allow_other 
$ sudo mkdir /mnt/data 
mkdir: cannot create directory ‘/mnt/data’: Input/output error 

 
 
Cause 

The policies don’t allow the dynamic group to manage Objects Storage. 

Solution 

As described on : 

To use instance principal authentication, a compute instance must be part of a dynamic group, and a policy must allow the dynamic group to manage Object Storage. You can use the manage object-family verb and resource type to define a policy that allows managing of Object Storage objects.
