Using SAMBA Toolkit in a Serviceguard Cluster README Revision: B.06.00

* Print Jobs
If a failover occurs when a print job is in process, the job may be
printed twice or not at all, depending on the job state at the time of
the failover.
* Symbolic Links
Symbolic links in the shared directory trees may point to files
outside of any shared directory. If symbolic links point to files
that are not on shared file systems, after a failover occurs, the
symbolic links may point to different files or to no file. Keeping
the targets of all shared symbolic links synchronized with all nodes
at all times could be difficult in this situation.
Alternatives would either be to set wide links to "no", or to be sure
that every file or directory pointed to is on a shared file system.
* Security Files and Encrypted Passwords
Authentication is dependent on several entries in different security
files. An important security file is the user password file,
smbpasswd. If your CIFS Server is configured with encrypt passwords
set to "yes", use an smbpasswd file. By default, this file is located
in the path /var/opt/samba/private but a different path may be
specified via the 'smb passwd file' parameter.
Another important security file is secrets.tdb. Machine account
information is among the important contents of this file. Since this
file will be updated periodically (as defined in smb.conf by 'machine
password timeout', 604800 seconds by default), HP recommends that you
locate secrets.tdb on a shared storage. As with the smbpasswd
file, discussed above, the location of this file is defined by the
smb.conf parameter 'smb passwd file'. For example, 'smb passwd file =
/var/opt/samba/shared_vol_1/private/smbpasswd' will result in the file
/var/opt/samba/shared_vol_1/private/secrets.tdb.
To summarize, both the machine account file (secrets.tdb) and the
password file (smbpasswd) should be put on shared storage.
* Username Mapping File
If the HP CIFS Server configuration is set to use a username mapping
file, it should be located on a shared file system. This way, if
changes are made, all the nodes will always be up-to-date. The
username mapping file location is defined in smb.conf by the parameter
'username map',
example, 'username map = /var/opt/samba/shared_vol_1/username.map'.
There is no username map file by default.
* HP CIFS Server as a WINS Server
If HP CIFS Server is configured as a WINS server (that is, the wins
