Parameters
- –? | –h | –help
- Displays a detailed description of this command, including syntax, parameter
descriptions, and examples. If you specify a help option, all other command
options are ignored.
- –quiet
- Turns off confirmation messages for this command.
- –nwhbthresh number
- Specifies the maximum number of missed network heartbeats before the metadata server declares a possible
path-failure problem with another metadata server in
the cluster. If this threshold is reached or exceeded and
the metadata server is running, the metadata server goes
into the not-running state, and stays in that state until it is repaired.
If the metadata server was not running, the ejected metadata server abnormally ends, restarts, and rejoins the cluster.
You
can specify a value from 1 to 100. The default value is 40.
- –nwhbinterval time
- Specifies the network heartbeat interval, in milliseconds, for periodic
pings among metadata servers in
the cluster. You can specify a value from 200 to 10 000. The default value
is 500.
- –clientretry number
- Specifies the maximum number of times a send can be attempted from the metadata server to the client before
declaring the client's session lease to be expired. You can specify a value
from 1 to 100. The default value is 5.
- –clientlease time
- Specifies the amount of time, in seconds, that a lock is leased to a client
when the metadata server grants
a lock. The metadata server applies
the client-lease-period multiplier to this value before ending the lease.
You can specify a value from 10 to 120. The default value is 20.
- –clientmultiplier number
- Specifies the client-lease-period multiplier. This multiplier accommodates
possible networking delays between the time a message gets sent from the client
until it is received by the metadata server.
You can specify a value from 0 to 4. A value of 0 prevents this multiplier
from affecting the client-lease period. The default value is 2.
- –diskhbthresh number
- Specifies the maximum number of missed disk heartbeats before the metadata server is dropped from the
cluster. You can specify a value from 1 to 100. The default value is 4.
- –diskhbinterval time
- Specifies the disk heartbeat interval, in milliseconds, for periodic pings
among metadata servers in the cluster.
You can specify a value from 200 to 10 000. The default value is 500.
- –lang
- Specifies the language that the metadata server runs. You can specify
one of these values:
- en_us
- United States English UTF8
- ja_jp
- Japanese UTF8
Note: This is a disruptive setting. If you change the language,
you must restart the cluster.
Prerequisites
This task must be performed only by trained service personnel.
You must have Administrator privileges to use the command.
You must be logged in to the operating system
on the engine hosting the master metadata server to
run this command.
Description
Note: Modifying
these settings requires you to reboot the cluster before changes will apply.
After
you run this command, you cannot run the chadvclusterconfig or chclusterconfig command
until you restart the cluster.
After you modify any of these disruptive
cluster settings, you cannot modify any cluster settings (using the chadvclusterconfigor chclusterconfig command) until you restart the cluster.
Restriction: This
command cannot be used when the cluster is quiesced.
Example
Changes the network heartbeat threshold The
following example changes the network heartbeat threshold to 10 missed heartbeats.
sfscli> chadvclusterconfig -nwhbthresh 10
Are you sure you want to change advanced cluster configuration settings,
which will require a immediate cluster restart for changes to apply? [y/n] Y
Cluster successfully modified. Restart the cluster for all changes to apply.
