Dataset properties

Property
Type & Description
state
string (DatasetState)

The state of the dataset:

  • attached - the dataset is coupled with its root file/directory, which means that the file/directory is treated as a dataset and offers some additional features (e.g. protection flags). The root file/directory contents are directly the dataset contents.

  • detached - the dataset is decoupled from its root file/directory and serves only archival purposes. The dataset does not correspond to any physical content in the file tree and changes to the original root file/directory contents are not reflected in the dataset.

    A detached dataset can be reattached, but only to the original file/directory and only if it still exists. Once a dataset has been established, its root file/directory can no longer be changed.

Enum:
attached detached
setProtectionFlags
array of strings

Dataset protection flags:

  • data_protection - causes all dataset's files and directories to be protected from modifying their content.

  • metadata_protection - causes all dataset's files and directories to be protected from modifying their metadata (custom metadata, ACL, etc.). Can be enabled only when data_protection is enabled.

NOTE: the file/directory can be deleted if data_protection flag is disabled, or when the flag is enabled but is inherited through one of its hard links.

Requests to modify the data/metadata when protection is enabled will be rejected with the EPERM POSIX error.

The protection flags are ignored when the dataset is in detached state.

Changing the protection flags may not have an immediate effect, especially for files that were already opened before the change.

Note however that some basic readonly file attributes (such as e.g. atime updated when a file is read) will be modified regardless.

unsetProtectionFlags
array of strings

Dataset protection flags:

  • data_protection - causes all dataset's files and directories to be protected from modifying their content.

  • metadata_protection - causes all dataset's files and directories to be protected from modifying their metadata (custom metadata, ACL, etc.). Can be enabled only when data_protection is enabled.

NOTE: the file/directory can be deleted if data_protection flag is disabled, or when the flag is enabled but is inherited through one of its hard links.

Requests to modify the data/metadata when protection is enabled will be rejected with the EPERM POSIX error.

The protection flags are ignored when the dataset is in detached state.

Changing the protection flags may not have an immediate effect, especially for files that were already opened before the change.
