Symptoms

Ao montar uma exportação NFS para um client, o caminho do arquivo é exibido como não encontrado.

No client NFS, ao tentar montar a exportação:
Comando: 
# sudo mount -t nfs -o vers=3,sec=sys,proto=tcp <ECS IP>:<Remote Export Path> <Local Mount Point>
Exemplo: 
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 confirmado nos registros do ECS:
Comando: 
# egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log
Exemplo: 
admin@node1~> egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log

Cause

Isto é previsto. Guia do administrador do ECS destacado:

Acesso multiprotocolo NFS S3 a diretórios e arquivos

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.

Isso significa que /NS1/NFS_Bucket/Bos1 não é um diretório no que diz respeito ao NFS. 

/NS1/NFS_Bucket/Bos1 é considerado como diretório quando há um objeto ou arquivo em /Bos1/.

Resolution

Crie um:

  • Namespace = NS1
  • Bucket = NFS_Bucket
  • Diretório = Bos1 
  • ESCREVA/CARREGUE UM objeto (qualquer objeto) em Bos1 antes de tentar montar /NS1/NFS_Bucket/Bos1.

Isso trata Bos1 como um diretório e /NS1/NFS_Bucket/Bos1 Pode ser montado.
