Experienced the same issue here and found a solution: Server A: 12.04.1, 3.2.0-34-generic, NFSv4 exports to sub-net Client B: 12.04.2, 3.6.0-030600rc4-generic Client C: 12.04.2, 3.6.0-030600-generic
All systems have the same user accounts with identical IDs. Client B would see the correct file ownership: $ ls -al /home/all/Library/ total 40 drwxrwxr-x 10 tj users 4096 Jan 22 13:33 . drwxrwxr-x 9 tj users 4096 Sep 19 14:59 .. drwxrwxr-x 8 tj users 4096 Mar 8 2012 Backup drwxrwxr-x 7 tj users 4096 Nov 22 22:40 BLOB drwxrwxr-x 3 tj users 4096 Jan 22 14:29 Downloads drwxrwxr-x 10 tj users 4096 Sep 29 20:56 iso-image drwxrwxr-x 12 tj users 4096 Jul 24 2012 Media drwxrwxr-x 5 tj users 4096 Jan 26 15:10 Projects drwxrwxr-x 16 tj users 4096 Jan 30 22:35 SourceCode drwxrwxr-x 3 tj users 4096 Aug 18 07:49 VirtualMachines Client C would not: $ ls -al /home/all/Library/ total 40 drwxrwxr-x 10 nobody users 4096 Jan 22 13:33 . drwxrwxr-x 9 tj users 4096 Sep 19 14:59 .. drwxrwxr-x 8 nobody users 4096 Mar 8 2012 Backup drwxrwxr-x 7 nobody users 4096 Nov 22 22:40 BLOB drwxrwxr-x 3 nobody users 4096 Jan 22 14:29 Downloads drwxrwxr-x 10 nobody users 4096 Sep 29 20:56 iso-image drwxrwxr-x 12 nobody users 4096 Jul 24 2012 Media drwxrwxr-x 5 nobody users 4096 Jan 26 15:10 Projects drwxrwxr-x 16 nobody users 4096 Jan 30 22:35 SourceCode drwxrwxr-x 3 nobody users 4096 Aug 18 07:49 VirtualMachines Server A has several LVs that are rbind-mounted to the NFS root via /etc/fstab: /home/all/Library /srv/Library none defaults,rbind,noauto 0 0 and exported: /srv 10.254.0.0/16(rw,sync,no_subtree_check,crossmnt,fsid=0) /srv/Library 10.254.0.0/16(rw,sync,no_subtree_check,crossmnt) /srv/Library/Backup 10.254.0.0/16(rw,sync,no_subtree_check) /srv/Library/BLOB 10.254.0.0/16(rw,sync,no_subtree_check) /srv/Library/Media 10.254.0.0/16(rw,sync,no_subtree_check,crossmnt) /srv/Library/iso-image 10.254.0.0/16(rw,sync,no_subtree_check) /srv/Library/VirtualMachines 10.254.0.0/16(rw,sync,no_subtree_check) /srv/Library/SourceCode 10.254.0.0/16(rw,sync,no_subtree_check) /srv/Library/Projects 10.254.0.0/16(rw,sync,no_subtree_check) Clients B and C have identical /etc/fstab entries: 10.254.251.1:/Library /home/all/Library nfs4 _netdev,auto,exec 0 0 and /etc/idmapd.conf: [General] Verbosity = 0 Pipefs-Directory = /run/rpc_pipefs Domain = lan.eddie.tj [Mapping] Nobody-User = nobody Nobody-Group = nogroup Server A has the same idmapd.conf with the addition of: [Translation] Method = nsswitch I found the solution here was to add the [Translation] stanza to client C's configuration (and restart the idmapd service). I don't understand why client B can correctly translate the user IDs without having the [Translation] stanza, though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/976632 Title: nfs4 mounts are not mapping userids, uses nobody/nogroup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/976632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
