lrs_sched: ordered grouped read The grouped read scheduler is now able to order the request by following their COS and priority, ie: the ctime of the corresponding copy. This patch integrates the github pull request #55. Change-Id: I362785693fd685f08330f699ecd2db8f0d1f25a1 Signed-off-by: Patrice LUCAS <patrice.lucas@ayudata.fr>

proto: add qos and priority to request These new qos and priority fields will offer scheduling opportunities.

DSS: adding library columns These columns will allow us to manage a multi-library configuration. Library is added to device, media and extent tables. Name column is no more UNIQUE as we consider we can have media with the same label in two different libraries. The library column must have a value. The phobos configuration file must contain the default value per family : tape, dir, rados pool. The library is added to the pho_id structure. The grouped_read queue key changes from medium name to complete medium_id. The lrs media cache functions to hash and test equality are mutualized with grouped read to take into account the whole pho_id structure and not only the field name.

lrs: avoid already allocated drive selection In case a client try to allocate a second drive but there is only one available, the scheduler will consider the first drive as selectable and wait for its release, which provokes a deadlock. Now, a drive allocated by the same client cannot be considered selectable if both are needed for the same operation. A boolean is also added to the communication protocol with the LRS to distinguish client which requests multiple allocations for one operation (repack) or for multiple operations (mput). The boolean `prevent_duplicate` will be set to `true` if allocations are bound to the same operation and `false` otherwise.

refactor: move dss "drive add" code to the admin module Now that admin operations require to notify the daemon if it is online, we want to remove all dss-related code from the CLI to add it in the admin module and let the CLI only be a command line interpreter.

phobosd: allow the utilization of multiple schedulers Until now, the daemon could only manage one family of resources (tape or directory) at a time. This family was defined using the PHOBOS_LRS_default_family env variable. Instead of setting only one scheduler, the daemon can now initialize a scheduler per family, depending on those requested using the PHOBOS_LRS_families env variable. Users can now indicate to which family they send their data using the PHOBOS_STORE_default_family env variable. This piece of information is now a part of the write alloc request protocol.

admin: new module to launch admin phobos commands (format, device_add) Because of LRS daemonization, a format or notify request needs to be sent to the LRS via the transfer protocol. Also, as they are not issued from user commands (format and device_add), they can not be a part of phobos_store. The phobos_admin module will be in charge to connect to the LRS socket and send the format/notify request to it. Before the daemonization is done, it will also intialize a temporary LRS to communicate with. The notify request is for now used to notify the LRS that a device was added to the DSS, and that it needs to load its state. This request can then be used to inform the LRS about various state changes: like lock, unlock, rm, etc. Change-Id: I6c217cb701e99236e09676b53a62adff3a5691ad Signed-off-by: Sebastien Gougeaud <sebastien.gougeaud@cea.fr> Reviewed-on: https://cws-fleury.labs.ocre.cea.fr/gerrit/5157 Reviewed-by: Linter Tested-by: Jenkins s8open_nr <s8open_nr@ccc.ocre.cea.fr> Reviewed-by: Patrice LUCAS <patrice.lucas@cea.fr> Reviewed-by: Thomas Leibovici <thomas.leibovici@cea.fr>
