증상

Beim Mounten eines NFS-Exports auf einem Client wird der Dateipfad als nicht gefunden angezeigt.

Gehen Sie auf dem NFS-Client beim Versuch, den Export zu mounten, wie folgt vor:
Befehl:
# sudo mount -t nfs -o vers=3,sec=sys,proto=tcp <ECS IP>:<Remote Export Path> <Local Mount Point>
Beispiel:
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
Bestätigtes Problem aus den ECS-Protokollen:
Befehl:
# egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log
Beispiel:
admin@node1~> egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log

원인

Dies ist beabsichtigt. ECS-Administratorhandbuch:

S3-NFS-Multiprotokollzugriff auf Verzeichnisse und Dateien

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. 

Das bedeutet, dass /NS1/NFS_Bucket/Bos1 ist kein Verzeichnis, soweit es NFS betrifft. 

/NS1/NFS_Bucket/Bos1 wird als Verzeichnis betrachtet, wenn sich ein Objekt oder eine Datei unter /Bos1/.

해결

Erstellen Sie eine:

  • Namespace = NS1
  • Bucket = NFS_Bucket
  • Verzeichnis = Bos1 
  • SCHREIBEN/HOCHLADEN eines Objekts (beliebiges Objekt) unter Bos1, bevor Sie versuchen, zu mounten /NS1/NFS_Bucket/Bos1.

Dadurch wird Bos1 als Verzeichnis behandelt und /NS1/NFS_Bucket/Bos1 montiert werden.
