3.9.7.4 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 acfs0001_2fb06f13cddd4a8d8d636d1f794046cb

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

The ACFS file system is dismounted and the mount point directory is removed on every node in the Oracle Grid Infrastructure (GI) cluster. The command also removes the ACFS file system registration in the GI cluster. 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.
