3.9.6.4 Remove an ACFS File System on Exascale

Exascale contains integrated support for Oracle Advanced Cluster File System (ACFS) on Exascale block storage using Exascale Direct Volumes (EDV).

To delete and remove an existing Exascale-managed ACFS file system, use the ESCLI rmacfsfilesystem command and specify the identifier for the file system that is being removed. For example:

@> rmacfsfilesystem acfs-id

You can use the lsacfsfilesystem command to find the identifier for each Exascale-managed ACFS file system.

If the underlying EDV attachment is a node-specific attachment, the ACFS file system is dismounted and removed from the node containing the attachment. If the EDV attachment is a cluster-wide attachment, the file system is dismounted on every node in the Oracle Grid Infrastructure (GI) cluster. In all cases, the GI cluster registration is removed. Furthermore, the file system is removed from the underlying volume, effectively deleting the files in the file system. The command does not alter the underlying volume or volume attachment in any other way.
