Full Discussion: Increase disk size on OS side on the fly
Operating Systems SCO Increase disk size on OS side on the fly Post 302985038 by rbatte1 on Friday 4th of November 2016 05:30:35 AM

If you used tar to backup the entire system, you would need to put it back the data on a system with appropriate filesystems already mounted, that way tar will write them to the correct slice of disk.

If you are planning to restore everything and the backup was made with tar -cvf device / then you can only restore to the exact path. You will also need to make sure you don't overwrite OS critical files or your machine may not boot or fail to work properly.

Can you elaborate more on how you did the copy?

Again, Storix would be an excellent tool here (if it supports your OS version) and it would allow you to take a backup of your physical server that you can use to create a virtual server and update the disk allocations at the same time. It will help you go P2P, P2V, V2V & V2P.

I have to confirm that I have no financial interest in it, I just think it's a very good product. There are others available, but this one seems to do far more in a far more useful way. To be honest it exceeds what HP-UX's Ignite and AIX's mysysb do by adding in the ability to adjust various things (storage, network etc.) when you start the recovery. Take the free trial, watch the videos and choose for yourself.

Also have a look at the IBM view of it IBM - Storix System Backup Administrator (SBAdmin) for AIX



Kind regards,

quotaon

QUOTAON(8)						      System Manager's Manual							QUOTAON(8)

NAME

       quotaon, quotaoff - turn filesystem quotas on and off

SYNOPSIS

       quotaon [-v] filesystem ...
       quotaon [-v] -a
       quotaoff [-v] filesystem ...
       quotaoff [-v] -a

DESCRIPTION

       Quotaon	announces  to the system that disk quotas should be enabled on one or more filesystems.  Quotaoff announces to the system that the
       specified filesystems should have any disk quotas diskquotas turned off.  The filesystems specified must have entries in /etc/fstab and	be
       mounted.   Quotaon  expects  each  filesystem  to  have a quota file named quotas located at the root of the associated file system.  These
       defaults may be overridden in /etc/fstab.

       Available options:

       -a	      If the -a flag is supplied in place of any filesystem names, quotaon/quotaoff will enable/disable all the filesystems  indi-
		      cated in /etc/fstab to be read-write with disk quotas.

       -v	      Causes quotaon and quotaoff to print a message for each filesystem where quotas are turned on or off.

FILES

       quotas	      at the filesystem root with user quotas

       /etc/fstab     filesystem table

SEE ALSO

       quota(1), setquota(2), fstab(5), edquota(8), quotacheck(8), repquota(8)

HISTORY

       The quotaon command appeared in 4.2BSD.

4.2 Berkeley Distribution					 January 21, 1996							QUOTAON(8)
