Table 16-97 Options for the acfsutil snap convert command

Option	Description
`-r`	Converts snapshot to read-only snapshot.
`-w`	Converts snapshot to read-write snapshot.
`snapshot`	Specifies the name of the snapshot to be converted.
`mount_point`	Specifies the directory where the file system is mounted.

acfsutil snap convert converts the type of an existing snapshot image from a read-only snapshot image to a read-write snapshot image, or from a read-write snapshot image to a read-only snapshot image.

The type option (-r or -w) is required for the convert operation. Specifying a type parameter that matches the type of the existing snapshot image results in no conversion and no failure. An 11.2 read-only snapshot image can be converted to a read-write snapshot image, but this conversion results in an update of the Oracle ACFS on-disk structure version. After the Oracle ACFS on-disk structure version has been updated, the updated version is not compatible with previous Oracle ACFS 11.2 versions.

Administrator privileges are required to use this command or you must be a member of the Oracle ASM administrator group.
