3.5.1 Matrix Server Release Notes

PolyServe Release Notes 5

MxFS-Linux 3.5.1

This release adds support for the following operating systems:

• SuSE Linux Enterprise Server 9, SP 3 (64-bit only)

• Red Hat Enterprise Linux AS/ES 4.0, Update 4 (64-bit only)

This release includes the following implementation changes:

• When MxFS-Linux is installed, it now increases the values of several

tunable parameters:

– The number of NFS Server threads (specified by

RPCNFSDCOUNT

on Red Hat or USE_KERNEL_NFSD_NUMBER on SLES9) is increased

to 32.

– The maximum number of outstanding

NFS RPC requests for the

TCP network transport (specified by sunrpc.tcp_slot_table_entries)

is increased to 128.

– The maximum number of outstanding

NFS RPC

requests for the

UDP

network transport (specified by sunrpc.udp_slot_table_entries) is

increased to 128.

The new values are set in the /etc/sysconf/nfs file. If a larger value is

already configured, the existing value will not be changed.

• A new global NFS monitor is now used to check the health of the NFS

service and vital MxFS-Linux processes on each node. These tests

were previously done by the Export Group monitor. Because the tests

are for system conditions and do not need to be checked by more than

one monitor, they have been moved to the global NFS monitor. You

can configure the probe settings for the global NFS monitor as

necessary via the Management Console. See the PolyServe

Administration Guide for more information.

A new command, mx nfsprobe, is also available to configure the

global NFS monitor and to view its settings. The mx exportgroup

--timeout option is no longer used, as the timeout function has been

moved to the global NFS monitor. However, the command has not

been removed for compatibility with any user scripts that include it. If
