Un article pour vous montrer comment corriger et/ou supprimer les objets inaccessibles dans un cluster vSAN. Ce genre de problèmes arrivent lorsqu’on maltraite son cluster vSAN 🙁 mais étant en LAB rien de bien grave, mais il est important d’être vigilant si vous êtes en environnement de production pour ne pas reproduire ce genre de problématiques qui peuvent causer beaucoup de dégâts comme la perte de fichiers ou des VM qui passent en “inaccessible”.
Dans mon cas, le problème est apparu lors d’un changement de policy de stockage vSAN et en même temps j’ai éteint de façon très “sauvage” un de mes ESXi (pendant une longue durée) sans au préalable le mettre en mode maintenance….
La correction / suppression se fera en 4 étapes
- étape 1 : Scan complet du cluster à la recherche des “inaccessible vSAN objects”
- étape 2 : Purge des “inaccessible vswp objects”
- étape 3 : Nouveau scan complet du cluster
- étape 4 : Suppression des objets restants
étape 1
Se connecter en SSH sur le vCenter et lancer une console RVC

1 2 3 4 5 6 7 8 9 10 11 12 13 |
VMware vCenter Server Appliance 6.7.0.20000 Type: vCenter Server with an embedded Platform Services Controller Connected to service * List APIs: "help api list" * List Plugins: "help pi list" * Launch BASH: "shell" Command> shell Shell access is granted to root |
- Une fois le mot de passe renseigné vous devriez avoir :

1 2 3 |
0 / 1 localhost/ > |
- Dans RVC on se balade dans l’inventaire du vCenter avec les commandes “ls” et “cd“
|
1 |
cd localhost/LABDC/computers/ |
- Faire “ls” pour afficher les clusters disponibles

Lancez un check avec la commande vsan.check_state suivie du nom du cluster vSAN

/localhost/LABDC/computers> vsan.check_state CL-CMPT01 |
Vous devriez avoir un retour semblable à celui en dessous (Dans mon cas : Detected 50 objects to be inaccessible)

VM vswp file is used for memory swapping for running VMs by ESX. In VMware virtual SAN a vswp file is stored as a separate virtual SAN object. When a vswp object goes inaccessible, memory swapping will not be possible and the VM may crash when next time ESX tries to swap the memory for the VM. Deleting the inaccessible vswp object will not make thing worse, but it will eliminate the possibility for the object to regain accessibility in future time if this is just a temporary issue (e.g. due to network failure or planned maintenance). Due to a known issue in vSphere 5.5, it is possible for vSAN to have done incomplete deletions of vswp objects. In such cases, the majority of components of such objects were deleted while a minority of components were left unavailable (e.g. due to one host being temporarily down at the time of deletion). It is then possible for the minority to resurface and present itself as an inaccessible object because a minority can never gain quorum. Such objects waste space and cause issues for any operations involving data evacuations from hosts or disks. This command employs heuristics to detect this kind of left-over vswp objects in order to delete them. It will not cause data loss by deleting the vswp object. The vswp object will be regenerated when the VM is powered on next time.

Comme vous pouvez le voir tous les objets se trouvent dans le même ESXi qui est le esxi01a
étape 4
Dans cette étape, nous allons dans un premier temps nous connecter en ssh sur l’esxi qui contient les objets inaccessibles.
|
1 |
ssh root@esxi01a.mchelgham.lab |
Ensuite nous allons supprimer les objets 1 par 1 avec la commande ci dessous
|
1 |
/usr/lib/vmware/osfs/bin/objtool delete -u UUID -f -v 10 |
Vous devriez remplacer UUID par celui de votre objet
|
1 |
/usr/lib/vmware/osfs/bin/objtool delete -u 2be5725c-0584-c514-2d93-002655db0344 -f -v 10 |
Faire de même pour tous vos UUID inaccessibles…
Une fois terminé, refaire un scan du cluster avec la commande vsan.check_state suivie du nom du cluster et vous devriez avoir
