=head3 sfsSLconfig
Does statelite setup when using a shared file system
The snmove cmd changes the xcatmaster value for the nodes
This means, that since we won't be running mkdsklsnode again,
we need to take care of the ststelite file changes here
- update statelite tables in DB
- run dolitesetup to re-create the statelite files stored
in the shared_root directories
- copy the new statelite files to the shared_root directory
on the target service node (only one since this is a
shared filesystem
- note: not copying the persistent directory on the MN
Arguments:
Returns:
0 - OK
1 - error
Usage: $ret = &sfsSLconfig(\@nodelist, \%nhash, \%sn_hash, $nimprime,
$callback, $sub_req);
