Veritas Storage Foundation 5.1 SP1 Cluster File System Administrator"s Guide (5900-1738, April 2011)

Configuring Common Internet File System in user
mode
This section describes how to configure CIFS in user mode.
In this mode, user authentication happens on the cluster nodes itself.
You must have NIS or some other mechanism configured on the cluster nodes to
ensure the same users/groups have the same user/groups IDs on all cluster nodes.
A shared file system needs to be specified during the config operation. This file
system is used to store the smbpasswd file, which contains the encrypted passwords
for users. This way, users for whom passwords have been created on one cluster
node, can authenticate themselves against other cluster nodes as well.
You must backup your existing smb.conf file and ensure that the /var/log/samba
file exists on all cluster nodes, before running the cfsshare config command.
Note: If CNFS is already configured on the cluster, then specify the same
shared_volume and mount_point for configuration of CIFS.
cfsshare config [-n] -p cifs -l samba_lockdir -c \
samba_config_file -t samba_topdir -m user \
shared_disk_group shared_volume mount_point
For example:
# cfsshare config -p cifs -m user -l /var/run \
-c /etc/samba/smb.conf -t /usr lockdg vollocks /locks
Note: Check the path of the Samba lock directory and PID directory using the smdb
-b command. Use the path of the PID directory for the -l samba_lock option.
Note: The cfsshare config command fails if the shared_volume specified is
already registered with VCS. Verify that the shared_volume is not registered with
VCS by examining the output from the following command:
# /opt/VRTS/bin/cfsmntadm display
If the -n option is specified when using the cfsshare config command, you must
follow the steps to complete the CIFS configuration:
