  1. Exporting NFS File Systems to UNIX/ESXi Upon completion of this module, you should be able to: Export a file system to UNIX Describe exporting file systems to ESXi Exporting NFS File Systems to UNIX/ESXi

  2. Exporting NFS File Systems to UNIX/ESXi Lesson 1: Exporting a Mounted File System to UNIX This lesson covers the following topics: NFS Client mounts NFS user authentication Exporting NFS File Systems to UNIX/ESXi

  3. NFS Export • Network File System (NFS) protocol • Client or server distributed file service • Provides file sharing in network environments • VNX Data Mover or VDM is configured as an NFS server • Provides file system access for clients of NFS versions 2, 3 and 4 Data Mover Data File System Linux Client LAN NFS Server NFS Export VMware vSphere ESXi server and VMs Unix Client Exporting NFS File Systems to UNIX/ESXi

  4. Access Control • Client access to NFS Exports defined by • Hostname • Netgroup • Subnet • IP address • Authentication methods • Unix Security or AUTH_SYS security • Secure NFS • Authentication Daemon • All versions support UNIX security / PC authentication daemon • Only versions 3 and 4 support Secure NFS by using either UNIX/Linux or Windows Kerberos KDC Exporting NFS File Systems to UNIX/ESXi

  5. Mounting a File System to a Mountpoint • Storage > Storage Configuration • File Systems tab, right-click file system > Mounts > Create Mount • Mounts tab > Create • By default a file system is mounted when it is created Exporting NFS File Systems to UNIX/ESXi

  6. Mounting a File System to a Mountpoint: Configuration Exporting NFS File Systems to UNIX/ESXi

  7. Creating an NFS Export of a File System • Storage • Storage Configuration > File Systems • Right-click file system > NFS Exports > Create NFS Export • Shared Folders > NFS > Create Exporting NFS File Systems to UNIX/ESXi

  8. Creating an NFS Export of a File System: Configuration • Select the File System to export, define the path and access level Exporting NFS File Systems to UNIX/ESXi

  9. Mounting the File System from Clients (NFS) • NFS mount from client • Manual • Automatic (automounter) • Typical Procedure • Create or use an empty local directory as a mount point for the exported file system • NFS mount the local directory to the exported File System • mount <NFS server IP address or FQDN>:/<exported fs> /<mount point> • Example • # mount 192.168.1.106:/fs1 /studentX • View the file systems mounted on the client • mount • df –h Exporting NFS File Systems to UNIX/ESXi

  10. Permissions on the Created Directory • chmod command is used to set up permissions • chmod775 directory • rwx - owner • rwx - group • r-x - others Exporting NFS File Systems to UNIX/ESXi

  11. Export a File System Directory • Root of file system contains .etc and lost&founddirectories • Network users are unaware of the purpose of these directories • Best practice • Mount the file system at subdirectory level, export at that level and hide .etcand lost&found [root@linux-1 fs1]# ls –al drwxr-xr-x 5 root root 1024 Apr 6 09:05 . drwxr-xr-x 28 root root 4096 Apr 6 10:14 .. dr-xr-xr-x 2 root bin 80 Apr 6 09:05 .etc drwxr-xr-x 2 root root 8192 Apr 6 09:05 lost+found [root@linux-1 fs1]# Exporting NFS File Systems to UNIX/ESXi

  12. Create an Administrative Export to File System Root • Shared Folders > NFS • Create an NFS export • Select NFS Export and click Properties • Export file system with root permissions to client • Root Hosts option Create an NFS export to the file system top-level and assign root permissions to an administrative client Exporting NFS File Systems to UNIX/ESXi

  13. Creating a Directory Below the Exported File System • Create a directory below the exported file system • Set permissions for the newly created directory [root@linux-1 /]# mount 192.168.65.6:/fs01 /fs1 [root@linux-1 /]# cd /fs1 [root@linux-1 fs1]# mkdirengineering [root@linux-1 fs1]# chmod 775 engineering [root@linux-1 fs1]# chown -R epallisengineering [root@linux-1 fs1]# chgrp -R engpropengineering Mount export and create subdirectory with desired permissions for export [root@linux-1 fs1]# ls -l total 8 drwxr-xr-x 5 root root 1024 Apr 6 09:05 . drwxr-xr-x 28 root root 4096 Apr 6 10:14 .. dr-xr-xr-x 2 root bin 80 Apr 6 09:05 .etc drwxrwxr-x 2 epallisengprop80 Apr 6 10:35 engineering drwxr-xr-x 2 root root 8192 Apr 6 09:05 lost+found Exporting NFS File Systems to UNIX/ESXi

  14. Export the Subdirectory of File System • Create an export to the subdirectory of the file system • Grant the proper access rights to the NFS client Export subdirectory of file system to user community hosts Exporting NFS File Systems to UNIX/ESXi

  15. Mount the File System Sub-directory on NFS Client [root@linux-1 ~]# mkdir /engdir [root@linux-1 ~]# mount 192.168.65.6:/fs01/engineering /engdir Mount the subdirectory export on user community host and access the export [root@linux-1 ~]# cd /engdir [root@linux-1 engdir]# ls-l total 8 drwxrwxr-x 2 epallisengprop 80 Sep 18 08:06 . drwxr-xr-x 29 root root 4096 Sep 18 09:03 .. Exporting NFS File Systems to UNIX/ESXi

  16. Define NIS Using Unisphere • Settings > Network > Settings for File > Wizards > Edit DM DNS/NIS Exporting NFS File Systems to UNIX/ESXi

  17. Unexporting File Systems for NFS • Storage > Shared Folders > NFS • Right click the NFS export and select Delete • Or select the NFS Export from the list and click the Delete button • Confirm the operation on the dialog box Exporting NFS File Systems to UNIX/ESXi

  26. View: NFS Datastore on ESXi Host • To see the newly provisioned storage on the vCenter server • Click Summary tab > Resources or Configuration tab > Datastores Resources page on Summary tab Datastores page on Configuration tab Exporting NFS File Systems to UNIX/ESXi

  27. View: Provisioned Storage on the VNX Storage System • Unisphere connected to VNX • Properties of new file system that was NFS exported Exporting NFS File Systems to UNIX/ESXi

  28. View: ESXi and VMs on the VNX storage system • Hosts > Virtualization • Right-click existing ESXi or select Add vCenter server Exporting NFS File Systems to UNIX/ESXi

  29. Exporting NFS File Systems to UNIX/ESXi Lesson 2: Summary During this lesson the following topics were covered: VNX and ESXi interoperability Provisioning Storage for an NFS Share on a VNX Storage System Exporting NFS File Systems to UNIX/ESXi
