Symptoms

Quando si esegue il mounting di un'esportazione NFS su un client, il percorso del file viene visualizzato come non trovato.

Dal client NFS, quando si tenta di eseguire il mount dell'esportazione:
Comando:
# sudo mount -t nfs -o vers=3,sec=sys,proto=tcp <ECS IP>:<Remote Export Path> <Local Mount Point>
Esempio:
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
Problema confermato dai registri ECS:
Comando:
# egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log
Esempio:
admin@node1~> egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log

Cause

Si tratta del funzionamento previsto per progettazione. Guida dell'amministratore ECS indicata:

Accesso multiprotocollo NFS S3 a directory e file

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. 

Ciò significa che /NS1/NFS_Bucket/Bos1 non è una directory per quanto riguarda NFS. 

/NS1/NFS_Bucket/Bos1 è considerata come directory quando è presente un oggetto o un file in /Bos1/.

Resolution

Creare un:

  • Namespace = NS1
  • Secchio = NFS_Bucket
  • Directory = Bos1 
  • SCRIVERE/CARICARE un oggetto (qualsiasi oggetto) in Bos1 prima di tentare il mount /NS1/NFS_Bucket/Bos1.

In questo modo Bos1 viene trattato come una directory e /NS1/NFS_Bucket/Bos1 può essere montato.
