-
class HNASSSHBackend(backend_opts)
Bases: object
-
check_snapshot_parent(volume_path, snap_name, fs_label)
Check if a volume is the snapshot source
Parameters: |
- volume_path – path of the volume
- snap_name – name of the snapshot
- fs_label – filesystem label
|
Returns: | True if the volume is the snapshot’s source or False otherwise
|
-
file_clone(fs_label, src, name)
Clones NFS files to a new one named ‘name’.
Clone primitive used to support all NFS snapshot/cloning functions.
Parameters: |
- fs_label – file system label of the new file
- src – source file
- name – target path of the new created file
|
-
get_cloned_file_relatives(file_path, fs_label, raise_except=False)
Gets the files related to a clone
Parameters: |
- file_path – path of the cloned file
- fs_label – filesystem of the cloned file
- raise_except – If True exception will be raised for files that
|
aren’t clones. If False, only an error message is logged.
:returns: list with names of the related files
-
get_evs(fs_label)
Gets the EVS ID for the named filesystem.
Parameters: | fs_label – The filesystem label related to the EVS required |
Returns: | EVS ID of the filesystem |
-
get_evs_info()
Gets the IP addresses of all EVSs in HNAS.
Returns: | dictionary with EVS information |
- evs_info={
- <IP1>: {evs_number: number identifying the EVS1 on HNAS},
<IP2>: {evs_number: number identifying the EVS2 on HNAS},
...
}
-
get_export_list()
Gets information on each NFS export.
Returns: | a list of the exports configured on HNAS |
-
get_export_path(export, fs_label)
Gets the path of an export on HNAS
Parameters: |
- export – the export’s name
- fs_label – the filesystem name
|
Returns: | string of the export’s path
|
-
get_fs_info(fs_label)
Gets the information of a given FS.
Parameters: | fs_label – Label of the filesystem |
Returns: | dictionary with FS information |
- fs_info={
- ‘id’: a Logical Unit ID,
‘label’: a Logical Unit name,
‘evs_id’: the ID of the EVS in which the filesystem is created
(not present if there is a single EVS),
‘total_size’: the total size of the FS (in GB),
‘used_size’: the size that is already used (in GB),
‘available_size’: the free space (in GB)
}
-
get_version()
Gets version information from the storage unit.
Returns: | dictionary with HNAS information |
- storage_version={
- ‘mac’: HNAS MAC ID,
‘model’: HNAS model,
‘version’: the software version,
‘hardware’: the hardware version,
‘serial’: HNAS serial number}
