Cluster Configuration Check

Checking the cluster filer configuration

Matching filer configurations

When configuring filers as partners in a clustered environment, parameters, configuration files, licenses, and network interfaces must match. In this way, when a partner filer takes over for the failed filer, it appears the same as the failed filer.

After you have configured both filers, use the following tables to ensure that both filers match in their configuration.

Parameter matching

Compare the output of the options command for both filers in the cluster to ensure that each option has the same value in both filers.


options command options that must match
cifs.show_snapshot	dns.domainname
dns.enable	http.admin.enable
httpd.timeout	httpd.timewait.enable
vol.copy.throttle	ip.path_mtu_discovery.enable
nfs.per_client_stats.enable	nfs.v2.df.2gb.lim
nfs.v3.enable	nis.domainname
nis.enable	pcnfsd.enable
raid.reconstruct_speed	raid.timeout
wafl.maxdirsize	wafl.root_only_chown
cf.timed.enable
Other parameters that must match
Parameter	Command
ARP table	arp
date	date, rdate
NDMP on or off	ndmpd {on\|off}
NFS enabled	nfs {enable\|disable}
route table published	route
routed enabled	routed {on\|off}
time zone	timezone name

Configuration file matching

The following files must have identical contents:

/etc/resolv.conf
/etc/httpd.mimetypes
/etc/dgateways
/etc/nsswitch.conf

License matching

Licenses must match on both filers. For each feature you want, you must purchase a separate license for each filer. Fill in the license codes for your filers in the following table.


Feature	Filer 1 license code	File 2 license code
CIFS
Cluster
HTTP
NFS
