증상

Lors du montage d’une exportation NFS sur un client, le chemin d’accès au fichier s’affiche comme introuvable.

À partir du client NFS, lors de la tentative de montage de l’exportation :
Commande :
# sudo mount -t nfs -o vers=3,sec=sys,proto=tcp <ECS IP>:<Remote Export Path> <Local Mount Point>
Exemple :
admin@client~>$ sudo mount -t nfs -o vers=3,sec=sys,proto=tcp x.x.x.x:/NS1/NFS_Bucket/Bos1 /ecs_share
mount.nfs: mounting x.x.x.x:/NS1/NFS_Bucket/Bos1 failed, reason given by server: No such file or directory
Problème confirmé à partir des journaux ECS :
Commande :
# egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log
Exemple :
admin@node1~> egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log

원인

Cela est normal. Guide de l’administrateur d’ECS :

accès multiprotocole NFS S3 aux répertoires et fichiers

ECS supports writing objects using the S3 protocol and accessing them as files using NFS and, conversely, writing files using 
NFS and accessing the files as objects using the S3 protocol. You must understand how directories are managed when you use 
multi-protocol access.

The S3 protocol does not make provision for the creation of folders or directories.

To enable multi-protocol operation, ECS support for the S3 protocol formalizes the use of / and creates directory objects for all 
intermediate paths in an object name. An object named /a/b/c.txt results in the creation of a file object named c.txt and 
directory objects for a and b. The directory objects are not exposed to users through the S3 protocol, and are maintained only 
to provide multi-protocol access and compatibility with file system-based APIs. 

Cela signifie que /NS1/NFS_Bucket/Bos1 n’est pas un annuaire en ce qui concerne NFS. 

/NS1/NFS_Bucket/Bos1 est considéré comme un répertoire lorsqu’il existe un objet ou un fichier sous /Bos1/.

해결

Créer un :

  • Namespace = NS1
  • Bucket = NFS_Bucket
  • Répertoire = Bos1 
  • WRITE/UPLOAD an Object (Any Object) sous bos1 avant d’essayer le montage /NS1/NFS_Bucket/Bos1.

Cela traite Bos1 comme un répertoire et /NS1/NFS_Bucket/Bos1 peut être monté.
