copying a large filesystem
Hi there

In my organisation we have a solaris network with /home being automounted from /export/home on a central file server (usual stuff) however, the guy who originally set this up only allocated 3gb to /export/home and now we are really struggling for space. I have a new 18gb disk installed on the same box, it has been formatted and is ready to go. My problem is once i make sure everyone is out of their home directory, what would be the best procedure to copy all the data over to the new disk whilst retaining all folder and file permissions and then of course making it live !. I presume that I dont have to worry about it being called /export/home on the file server as i could share it out even if it was called /newhome ?. What changes to NIS would i need to make ? (automount files etc)

Apologies if this sounds dumb, its just that I have to make sure i dont mess it up, as we have production systems running from /home and it HAS to work in the morning

Cheers
Gary

createhomedir

createhomedir(1)					    BSD General Commands Manual 					  createhomedir(1)

NAME

     createhomedir -- create and populate home directories on the local computer.

SYNOPSIS

     createhomedir [-scbalh] [-n directoryDomainName] [-u username]

DESCRIPTION

     createhomedir provides several options for creating and populating home directories.

OPTIONS

     -s       creates home directories for server home paths only (default).

     -c       creates home directories for local home paths only.

     -b       creates home directories for both server and local home paths.

     -a       creates home directories for users defined in all directory domains of the server's search path.

     -l       creates home directories for users defined in the local directory domain.

     -L       causes the created home directory to be localized.

     -n directoryDomainName
	      creates home directories for users defined in a specific directory domain in the server's search path.

     -u username
	      creates a home directory for a specific user defined in the domain(s) identified in the -a, -l, or -n parameter. If you omit the -a,
	      -l, and -n parameters when you use the -u parameter, -a is assumed.

     -i       reads username list from standard input and creates specified home directories. Each username should be on its own line.

     -h       usage help.

FILES

     /usr/sbin/createhomedir			   location of tool

CAVEATS

     When using the -a option, search limits of various directory servers (such as Open Directory or Active Directory) can prevent all possible
     home directories from being created. In this case, you may need to specify the usernames explicitly.
