Issue

  • User cannot access files when 'nobody' is the owner
-rw-r--r--. 1 nobody groupname01 0 Aug 25 09:53 22222222222222222222222
-rw-r--r--. 1 nobody groupname01 0 Aug 25 09:53 222222222222222222222222
  • Issue occurs intermittently
  • The user id, uid, gid show the expected result:
[username01@machine01~]$ id
uid=1234(username01) gid=5678(groupname01)

  • getent passwd <uid> and getent group <gid>

    root@machine01[/root]#getent passwd 1234
    username01:PBIS:1234:5678::/share/home/username01:/bin/csh

    root@machine01[/root]#getent group 5678
    groupname01:PBIS:5678:username01

  • nfsidmap -d shows the correct domain ID:
root@machine01[/root]# nfsidmap -d
domain.com
  • On the cluster we find the same domain ID:
DKN_CLUS::> vserver nfs show -fields v4-id-domain
vserver   v4-id-domain
--------- ---------------------
SVM1      domain.com
  • The contents of /etc/idmapd.conf are also correct
  • Attempted to clear the current ID Domain and check /etc/idmapd.conf for a new value
root@machine01[/root]#nfsidmap -c
root@machine01[/root]#
