Symptoms

Når du monterer en NFS-eksport til en klient, vises filstien som ikke fundet.

Når du forsøger at starte eksporten fra NFS-klienten:
Kommando: 
# sudo mount -t nfs -o vers=3,sec=sys,proto=tcp <ECS IP>:<Remote Export Path> <Local Mount Point>
Eksempel: 
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
Bekræftet problem fra ECS-logfilerne:
Kommando: 
# egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log
Eksempel: 
admin@node1~> egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log

Cause

Det er udviklet til at fungere på denne måde. ECS-administratorvejledning skitseret:

S3 NFS-multiprotokoladgang til mapper og filer

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.

Det betyder, at /NS1/NFS_Bucket/Bos1 er ikke en fortegnelse for så vidt angår NFS. 

/NS1/NFS_Bucket/Bos1 betragtes som mappe, når der er et objekt eller en fil under /Bos1/.

Resolution

Opret en:

  • Navneområde = NS1
  • Spand = NFS_Bucket
  • Mappe = Bos1 
  • SKRIV/UPLOAD et objekt (ethvert objekt) under Bos1, før du prøver at montere /NS1/NFS_Bucket/Bos1.

Dette behandler Bos1 som en mappe og /NS1/NFS_Bucket/Bos1 kan monteres.
