Symptoms

När du monterar en NFS-export till en klient visas filsökvägen som att den inte hittades.

Från NFS-klienten när du försöker montera exporten:
Kommando: 
# sudo mount -t nfs -o vers=3,sec=sys,proto=tcp <ECS IP>:<Remote Export Path> <Local Mount Point>
Exempel: 
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
Bekräftat problem från ECS-loggarna:
Kommando: 
# egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log
Exempel: 
admin@node1~> egrep 'ERROR_OBJECT_NOT_FOUND|nfsProcessOperation' /opt/emc/caspian/fabric/agent/services/object/main/log/dataheadsvc.log

S3 NFS-multiprotokollåtkomst till kataloger och 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.

Detta innebär att /NS1/NFS_Bucket/Bos1 är inte en katalog när det gäller NFS. 

/NS1/NFS_Bucket/Bos1 betraktas som katalog när det finns ett objekt eller en fil under /Bos1/.

Resolution

Skapa en:

  • Namnrymd = NS1
  • Hink = NFS_Bucket
  • Katalog = Bos1 
  • SKRIV / LADDA upp ett objekt (valfritt objekt) under Bos1 innan du försöker montera /NS1/NFS_Bucket/Bos1.

Detta behandlar Bos1 som en katalog och /NS1/NFS_Bucket/Bos1 kan monteras.
