Operating Systems Linux Red Hat Cloning an empty sever (except OS) onto a smaller drive? Post 302990880 by hicksd8 on Thursday 2nd of February 2017 06:02:10 AM

I would question why they wish to 'clone' the server in the first place. Do they have another identical hardware platform to put it on? If they clone the disk(s) I would say that they need to fully test that clone elsewhere in order to have confidence in it.

I would be inclined to research the correct disaster recovery (DR) from backup procedure for that OS. What format of backup media would be required. If the box is to become a production system then they MUST have a backup device (eg, tape drive) or a remote NFS volume to backup to. That backup (of which multiple copies could be taken e.g. for off-site storage too) could be kept indefinitely. The point you are making is that the system is the data NOT the hardware. Indeed, by definition, the DR would be designed to work on completely different hardware in case the computer room caught fire, the hardware was destroyed, and the same model hardware is no longer available. With a DR backup it would be possible to recover the system even if it took a little time. The data would be available to restore the system.

Usually, it is also important to have hardcopy of the disk layout, partition sizes, filesystem sizes, cylinder numbers, swap space, etc. That combined with a DR backup provides everything for recovery. By comparison, if you clone the system to a second drive and that drive fails (or somebody drops it on the floor) you are stuffed.

I'm not a CentOS expert but those are my thoughts in generic terms.

ypset(1M)						  System Administration Commands						 ypset(1M)

NAME
ypset - point ypbind at a particular server SYNOPSIS
/usr/sbin/ypset [-d ypdomain] [-h host] server DESCRIPTION
In order to run ypset, ypbind must be initiated with the -ypset or -ypsetme options. See ypbind(1M). ypset tells ypbind to get NIS services for the specified ypdomain from the ypserv process running on server. If server is down, or is not running ypserv, this might not be dis- covered until an NIS client process tries to obtain a binding for the domain. At this point, the binding set by ypset is tested by ypbind. If the binding is invalid, ypbind attempts to rebind for the same domain. ypset is useful for binding a client node that is not on a broadcast net, or is on a broadcast net that is not running an NIS server host. It is also useful for debugging NIS client applications, for instance, where an NIS map exists only at a single NIS server host. Where several hosts on the local net are supplying NIS services, ypbind can rebind to another host, even while you attempt to find out if the ypset operation succeeded. For example, if you enter the ypset command below, you might get the subsequent response from ypwhich: example% ypset host1 example% ypwhich host2 The sequence shown above is a function of the NIS subsystem's attempt to load-balance among the available NIS servers, and occurs when host1 does not respond to ypbind because it is not running ypserv (or is overloaded), and host2, running ypserv, obtains the binding. server indicates which NIS server to bind to, and must be specified as a name or an IP address. This works only if the node has a current valid binding for the domain in question and ypbind has been set to allow use of ypset. In most cases, server should be specified as an IP address. ypset tries to bind over a connectionless transport. The NIS library call, yp_all(), uses connection-oriented transport and derives the NIS server's address based on the connectionless address supplied by ypset. Refer to ypfiles(4) for an overview of the NIS name service. OPTIONS
-d ypdomain Use ypdomain, instead of the default domain. -h host Set ypbind's binding on host, instead of locally. Specify host as a name. ATTRIBUTES
