| + | |||
| + | Pour les systèmes qui utilisent le micrologiciel UEFI (Unified Extensible Firmware Interface), GPT est la norme pour le partitionnement des disques et répond aux limites du schéma MBR. GPT offre un maximum de 128 partitions au maximum. Le schéma GPT alloue 64 bits pour les adresses de blocs logiques, afin de prendre en charge des partitions et des disques allant jusqu' | ||

| + | Le partitionnement GPT offre des fonctionnalités et des avantages supplémentaires par rapport au MBR. GPT utilise un identifiant unique (GUID) pour identifier chaque disque et chaque partition. GPT rend la table de partition redondante avec le GPT primaire en tête de disque et un GPT secondaire de sauvegarde à la fin du disque.

| + | =====RAID Logiciel===== | ||
| + | |||
| + | =====Concepts RAID===== | ||
| + | |||
| + | Les solutions RAID ou //Redundant Array of Independent Disks// ou encore //Redundant Array of Inexpensive Disks// permettent la combinaison de plusieurs disques de façon à ce que ceux-ci soient vu comme un seul disque logique. | ||
| + | |||
| + | Les solutions RAID sont issues du travail fourni par l' | ||
| + | |||
| + | * Addition des capacités, | ||
| + | * Amélioration des performances, | ||
| + | * Apporter la tolérance de panne. | ||
| + | |||
| + | Deux concepts sont fondamentaux à la compréhension des solutions RAID. | ||
| + | |||
| + | ====Disques en miroir==== | ||
| + | |||
| + | La technique des disques en miroir consiste à dupliquer l' | ||
| + | |||
| + | ====Bandes de données==== | ||
| + | |||
| + | La technique des bandes de données, autrement appelée //data striping// consiste à couper les données à enregistrer en segments séquentiels et contigus pour les enregistrer sur plusieurs disques physiques. L' | ||
| + | |||
| + | =====Types de RAID===== | ||
| + | |||
| + | ====RAID 0 - Concaténation==== | ||
| + | |||
| + | Création de volume par récupération de l' | ||
| + | |||
| + | {{: | ||
| + | |||
| + | ===Avantages=== | ||
| + | |||
| + | * Récupération de l' | ||
| + | |||
| + | ===Inconvénients=== | ||
| + | |||
| + | * Pas de protection des données, | ||
| + | * Pas d' | ||
| + | |||
| + | ====RAID 0 - Striping==== | ||
| + | |||
| + | Création de volume sur plusieurs disques afin d' | ||
| + | |||
| + | {{: | ||
| + | |||
| + | ===Avantages=== | ||
| + | |||
| + | * Augmentation des performances d'E/S par écriture en parallèle sur les disques. | ||
| + | |||
| + | ===Inconvénients=== | ||
| + | |||
| + | * Pas de protection des données. | ||
| + | |||
| + | ====RAID 1 - Miroir==== | ||
| + | |||
| + | Création d'un volume où les disques sont en miroir. Quand les deux disques sont connectés à des contrôleurs de disques différents, | ||
| + | |||
| + | {{: | ||
| + | |||
| + | ===Avantages=== | ||

| + | |||
| + | * Coûteux à cause de l' | ||
| + | |||
| + | ====RAID 1+0 - Striping en Miroir==== | ||
| + | |||
| + | Le RAID 1+0 ou encore 0+1 est une technique qui réunit le RAID 0 et le RAID 1. On l' | ||

| + | |||
| + | Le RAID 2 est une technique de miroir avec contrôle de correction d' | ||
| + | |||
| + | ====RAID 3 et 4 - Striping avec Parité==== | ||
| + | |||
| + | Les RAID 3 et 4 sont des technologies avec bandes de parité distribuées sur un seul disque : | ||
| + | |||
| + | {{: | ||
| + | |||
| + | En RAID 3, la taille des segments n’est pas modifiable et est fixée à 512 octets (en RAID 3 : un segment = un secteur de disque dur = 512 octets). | ||
| + | |||
| + | En RAID 4, la taille des segments est variable et se modifie en temps réel. Cela implique que les informations de parité doivent être mise à jour à chaque écriture afin de vérifier si la taille des segments a été modifiée. | ||
| + | |||
| + | ===Avantages=== | ||
| + | |||
| + | * Protection des données contre une défaillance d'un disque. | ||
| + | |||
| + | ===Inconvénients=== | ||

| + | * Création d'un goulot d' | ||
| + | |||

| + | |||
| + | Le RAID 5 est une technologie avec bandes de parité distribuées sur plusieurs disques : | ||
| + | |||
| + | {{: | ||
| + | |||
| + | ===Avantages=== | ||
| + | |||
| + | * Protection des données contre une défaillance d'un disque, | ||
| + | * Evite le goulot d' | ||

| + | ===Inconvénients=== | ||
| + | |||
| + | * Lecture moins performante qu' | ||
| + | |||
| + | ====Au délà de RAID 5==== | ||
| + | |||
| + | Il existe aussi deux autres technologies RAID, toute deux issues de la technologie RAID 5 : | ||
| + | |||
| + | * RAID 6 | ||
| + | * //Disk Striping with Double Distributed Parity// | ||
| + | * RAID TP | ||
| + | * //Disk Striping with Triple Distributed Parity// | ||

| + | =====LAB #12 - Stratis===== | ||
| + | |||
| + | ====12.1 - Présentation==== | ||
| + | |||
| + | **Stratis** est une solution de gestion de volumes et de stockage pour Linux, développée par Red Hat, qui combine des technologies comme **LVM (Logical Volume Manager)** et **XFS** pour fournir une gestion simplifiée des volumes de stockage. Il est conçu pour offrir une solution robuste et facile à utiliser, tout en offrant une gestion avancée du stockage comme la gestion des snapshots, le thin provisioning, | ||
| + | |||
| + | Voici un aperçu de la gestion du stockage avec Stratis : | ||
| + | |||
| + | ===Concepts clés de Stratis=== | ||
| + | |||
| + | * **Pool de stockage** : Un pool est une collection de disques physiques (ou d' | ||
| + | * **Volumes logiques** : Une fois que vous avez un pool, vous pouvez créer des volumes logiques (ou systèmes de fichiers). Ces volumes logiques peuvent être utilisés comme tout autre système de fichiers dans Linux. Ils peuvent être agrandis ou réduits dynamiquement, | ||
| + | * **Thin provisioning** : Stratis permet de créer des volumes logiques "thin provisioned", | ||
| + | * **Snapshots** : Stratis permet de créer des snapshots, qui sont des copies instantanées des volumes à un moment donné. Ces snapshots peuvent être utilisés pour des sauvegardes ou pour restaurer un état précédent du système de fichiers. | ||
| + | |||
| + | ===Gestion simplifiée=== | ||
| + | |||
| + | L’un des principaux objectifs de Stratis est de simplifier la gestion des volumes. Il combine plusieurs technologies complexes (comme LVM, D-Bus, et XFS) sous une interface de gestion unique, accessible via des commandes simples. | ||
| + | |||
| + | ===Avantages de Stratis=== | ||
| + | |||
| + | * **Facilité d' | ||
| + | * **Thin provisioning** et **snapshots** intégrés, | ||
| + | * **Gestion dynamique** des disques et des volumes, sans avoir besoin de redémarrer le système, | ||
| + | * **Snapshots** rapides pour des sauvegardes ou restaurations faciles. | ||
| + | |||
| + | ===Stratis vs ZFS/ | ||
| + | |||
| + | Stratis est parfois comparé à d' | ||
| + | |||
| + | En résumé, Stratis simplifie la gestion du stockage en regroupant plusieurs fonctionnalités avancées dans un cadre simple et accessible pour les administrateurs Linux, tout en utilisant des technologies éprouvées. | ||
| + | |||
| + | ====12.2 - Travailler avec Stratis==== | ||
| + | |||
| + | ===Installation=== | ||
| + | |||
| + | Le support de Stratis peut être obtenu en installant les paquets **stratisd** et **stratis-cli** : | ||
| + | |||
| + | < | ||
| + | [root@redhat9 ~]# dnf install stratisd stratis-cli -y | ||
| + | </ | ||
| + | |||
| + | Activez et démarrez le service stratis : | ||
| + | |||
| + | < | ||
| + | [root@redhat9 ~]# systemctl enable --now stratisd | ||
| + | |||
| + | [root@redhat9 ~]# systemctl status stratisd | ||
