Symptoms

Podczas montowania eksportu NFS na kliencie ścieżka pliku jest wyświetlana jako Nie znaleziono.

Z poziomu klienta NFS, podczas próby zamontowania eksportu:
Polecenie:
# sudo mount -t nfs -o vers=3,sec=sys,proto=tcp <ECS IP>:<Remote Export Path> <Local Mount Point>
Przykład:
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
Potwierdzono problem z dzienników ECS:
Polecenie:
# egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log
Przykład:
admin@node1~> egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log

Cause

Jest to zamierzone. Podręcznik administratora ECS:

wieloprotokołowy dostęp NFS S3 do katalogów i plików

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. 

Oznacza to, że /NS1/NFS_Bucket/Bos1 nie jest katalogiem w rozumieniu NFS. 

/NS1/NFS_Bucket/Bos1 jest uznawany za katalog, gdy w obszarze znajduje się obiekt lub plik /Bos1/.

Resolution

Utwórz:

  • Przestrzeń nazw = NS1
  • Łyżka = NFS_Bucket
  • Katalog = Bos1 
  • ZAPISZ/PRZEŚLIJ obiekt (dowolny obiekt) w Bos1 przed próbą zamontowania /NS1/NFS_Bucket/Bos1.

To traktuje Bos1 jako katalog i /NS1/NFS_Bucket/Bos1 można zamontować.
