Symptoms

The system displays duplicate NFS aliases with the same name, which reference the same ifs directory path.

Cause

The root cause of the issue is the creation of an additional alias with the same name plus a space suffix. This additional alias results in the display of "duplicate" lines on the aliases list.

Resolution

The recommended solution is to remove the "duplicate" alias name with the space suffix. This is purely a display issue and there is nothing wrong from the NFS perspective.

Here are the steps to identify the duplicates:
  1. Run:
isi --debug nfs aliases list
2024-03-06 10:29:15,982 DEBUG rest.py:72: >>>GET ['protocols', 'nfs', 'aliases']
 2024-03-06 10:29:15,982 DEBUG rest.py:74:   args={}
  body={}
 2024-03-06 10:29:16,160 DEBUG rest.py:96: <<<(200, {'status': '200 Ok', 'content-type': 'application/json', 'allow': 'GET, POST, HEAD'}, '\n{\n"aliases" : \n[\n\n{\n"health" : "unknown",\n"id" : "/Test",\n"name" : "/Test",\n"path" : "/ifs/data",\n"zone" : "System"\n},\n\n{\n"health" : "unknown",\n"id" : "/Test ",\n"name" : "/Test ",\n"path" : "/ifs/data",\n"zone" : "System"\n}\n],\n"resume" : null,\n"total" : 2\n}\n')
 Zone  Name      Path
 ---------------------------
 System /Test/ifs/data
 System /Test /ifs/data
 ---------------------------
Notice the differences in the /Test paths with and without space: 
With Space:    "/Test ",\n"name" : "/Test ",\n"path"
Without Space: "/Test",\n"name" : "/Test",\n"path"
