Ask Linux.com: Historical Linux, hardware for tomorrow
11-08-2008 07:00 AM
It's all about bipartisanship and unity in this week's roll call for the Linux.com forums. Old distro and new distro coming together, peripheral and computer learning how to work as one, and, just as the framers intended, a run-off between several distinguished "absentee answer" questions.
Hello,
I am working on a Perl script to run from an AIX Nim server to extract hardware errors from our Linux server using various forms of grep statements -

We have run software on Dell Servers w/ Windows and seen the performance degrade overtime. We switched to an IBM server w/ AIX and have not seen the same performance degradation over time. In fact, the IBM servers are at least five years old and continue to preform well at the same level.

Before posting questions about Linux hardware, it is a good idea to check the Linux Hardware HOWTO guide (Last Update: 2007-05-22)
However, this HOWTO has not been maintained since 2007 and it out-of-date. (0 Replies)
I'm really new to this and I want to learn UNIX/LINUX and saw the post about setting up a server to use everyday to practice. I have an old 386 PC and a 486 PC sitting around. Can they be reformatted and used to run UNIX/LINUX on as a network. (4 Replies)
OCF_HEARTBEAT_NFSSER(7) OCF resource agents OCF_HEARTBEAT_NFSSER(7)NAME
ocf_heartbeat_nfsserver - Manages an NFS server
SYNOPSIS
nfsserver [start | stop | monitor | meta-data | validate-all]
DESCRIPTION
Nfsserver helps to manage the Linux nfs server as a failover-able resource in Linux-HA. It depends on Linux specific NFS implementation
details, so is considered not portable to other platforms yet.
SUPPORTED PARAMETERS
nfs_init_script
The default init script shipped with the Linux distro. The nfsserver resource agent offloads the start/stop/monitor work to the init
script because the procedure to start/stop/monitor nfsserver varies on different Linux distro. In the event that this option is not
set, this agent will attempt to use an init script at this location, /etc/init.d/nfsserver, or detect a systemd unit-file to use in the
event that no init script is detected.
(optional, string, default "auto detected")
nfs_notify_cmd
The tool to send out NSM reboot notification; it should be either sm-notify or rpc.statd. Failover of nfsserver can be considered as
rebooting to different machines. The nfsserver resource agent use this command to notify all clients about the occurrence of failover.
(optional, string, default "/sbin/sm-notify")
nfs_notify_foreground
Keeps the notify tool attached to its controlling terminal and running in the foreground.
(optional, boolean, default false)
nfs_smnotify_retry_time
Specifies the length of sm-notify retry time, in minutes, to continue retrying notifications to unresponsive hosts. If this option is
not specified, sm-notify attempts to send notifications for 15 minutes. Specifying a value of 0 causes sm-notify to continue sending
notifications to unresponsive peers until it is manually killed.
(optional, integer, no default)
nfs_shared_infodir
The nfsserver resource agent will save nfs related information in this specific directory. And this directory must be able to fail-over
before nfsserver itself.
(required, string, no default)
nfs_ip
Comma separated list of floating IP addresses used to access the nfs service
(required, string, no default)
rpcpipefs_dir
The mount point for the sunrpc file system. Default is /var/lib/nfs/rpc_pipefs. This script will mount (bind) nfs_shared_infodir on
/var/lib/nfs/ (cannot be changed), and this script will mount the sunrpc file system on /var/lib/nfs/rpc_pipefs (default, can be
changed by this parameter). If you want to move only rpc_pipefs/ (e.g. to keep rpc_pipefs/ local) from default, please set this value.
(optional, string, default "/var/lib/nfs/rpc_pipefs")
SUPPORTED ACTIONS
This resource agent supports the following actions (operations):
start
Starts the resource. Suggested minimum timeout: 40.
stop
Stops the resource. Suggested minimum timeout: 20s.
monitor
Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 10.
meta-data
Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.
validate-all
Performs a validation of the resource configuration. Suggested minimum timeout: 30.
EXAMPLE
The following is an example configuration for a nfsserver resource using the crm(8) shell:
primitive p_nfsserver ocf:heartbeat:nfsserver
params
nfs_shared_infodir=string
nfs_ip=string
op monitor depth="0" timeout="20s" interval="10"
