_UpdateMasterClientCert(lu, master_uuid, cluster, feedback_fn, client_cert=pathutils.NODED_CLIENT_CERT_FILE, client_cert_tmp=pathutils.NODED_CLIENT_CERT_FILE_TMP)

source code

Renews the master's client certificate and propagates the config.

Parameters:

lu (LogicalUnit) - the logical unit holding the config
master_uuid (string) - the master node's UUID
cluster (objects.Cluster) - the cluster's configuration
feedback_fn (function) - feedback functions for config updates
client_cert (string) - the path of the client certificate
client_cert_tmp (string) - the temporary path of the client certificate

Returns: string

the digest of the newly created client certificate

_ValidateNetmask(cfg, netmask)

source code

Checks if a netmask is valid.

Parameters:

cfg (config.ConfigWriter) - The cluster configuration
netmask (int) - the netmask to be verified

Raises:

errors.OpPrereqError - if the validation fails

CheckFileBasedStoragePathVsEnabledDiskTemplates(logging_warn_fn, file_storage_dir, enabled_disk_templates, file_disk_template)

source code

Checks whether the given file-based storage directory is acceptable.

Note: This function is public, because it is also used in bootstrap.py.

Parameters:

logging_warn_fn (function) - function which accepts a string and logs it
file_storage_dir (string) - the directory to be used for file-based instances
enabled_disk_templates (list of string) - the list of enabled disk templates
file_disk_template (string) - the file-based disk template for which the path should be checked

CheckFileStoragePathVsEnabledDiskTemplates(logging_warn_fn, file_storage_dir, enabled_disk_templates)

source code

Checks whether the given file storage directory is acceptable.

See Also: CheckFileBasedStoragePathVsEnabledDiskTemplates

CheckSharedFileStoragePathVsEnabledDiskTemplates(logging_warn_fn, file_storage_dir, enabled_disk_templates)

source code

Checks whether the given shared file storage directory is acceptable.

_GetAllHypervisorParameters(cluster, instances)

source code

Compute the set of all hypervisor parameters.

Parameters:

cluster (objects.Cluster) - the cluster object
instances - list of objects.Instance
instances - additional instances from which to obtain parameters

Returns: list of (origin, hypervisor, parameters)

a list with all parameters found, indicating the hypervisor they apply to, and the origin (can be "cluster", "os X", or "instance Y")
