Dell DX6000G Setup And Configuration Manual

Syslog facility. If the syslog option was selected, enter the facility to log to. The default

value is local4. Configuration of a remote syslog host must be done in the syslogd

configuration file.

Log level. Enter the minimum level of log messages to record. The default value is info. Debug

is not recommended unless explicitly requested as part of a support investigation due to the

amount of disk space consumed that will not then be available for core processes. Each log

level includes the following:

• info: errors, warnings and information messages like system start up and stop

• verbose: errors, warnings, and info messages plus high-level operational functions

• debug: errors, warnings, info and verbose messages plus lower level operational functions

• trace: all possible log messages

Note

Debug or trace logging are not recommended unless explicitly requested as part

of a support investigation due to the amount of disk space consumed. If debug

logging is required for any length of time, administrators must monitor space

availability carefully and are strongly encouraged to allocate a dedicated partition

for logging to protect other system services.

CNS Host: The IP address or hostname of the name space server that will store the filesystem

metadata for the mount you are configuring. The default is localhost (127.0.0.1), which will

configure the share to use a name space on the local server. To use a name space configured

on a remote server, enter the external IP address for the previously created name space.

Note

If configuring a multi-server environment where more than one CFS server is sharing

a single CNS instance, you must enter the same CNS host information that was

entered in the cns-admin utility for each share. cfs-admin will generate a world

unique serial number for every created CFS share for internal use when requesting

exclusive file locks across all servers in the name space. This serial number is

stored with the CFS configuration files so they must not be copied from one server to

another to ensure the CFS share serial number is not duplicated.

CFS Time Horizon (Default=0d means no Timescapes): The time that deleted file system

objects will be kept in order to be available for a timescape mount of the file system at a time

in the past. Times are accepted in hours (i.e. 2h), days (i.e. 1d), months (i.e. 2m), or years (i.e.

1y). After the time horizon, deleted files are garbage collected from DX Storage and can no

longer be accessed.

10. Use Zeroconf for DX Storage configuration?. This option allows you to specify whether

or not Zeroconf should be used to discover the list of nodes in the DX Storage cluster. The

CFS server must be in the same subnet with DX Storage in order to use Zeroconf. CFS 2.6 is

compatible with DX Storage versions 3.0.5 and later.

If 'No' is selected:

Version 2.6
