- I think you should have in mind that wherever NFS is used, "the right UID" is always the major concern - and THAT's why NIS was invented in the first place (then NIS+ and now we use LDAP) ;

- if you have a legacy environment where NFS was deployed without taking the various UID into account - then ... sorry - you're doomed. Smilie

- but if you have a chance to do a fresh setup, then REMEMBER :

1) every username MUST have the same UID on ALL servers suitable to NFS perusal ;
2) it does not matter if you will accomplish this task 'manually' or thru NIS/NIS+/LDAP - the choice will only change the amount of work to see it done ;

It's all I have to say about that Smilie

HTH

good luck, and success !

vgsync

vgsync(1M)																vgsync(1M)

NAME

       vgsync - synchronize stale logical volume mirrors in LVM volume groups

SYNOPSIS

       vg_name ...

   Remarks
       This  command  requires	the  installation of the optional HP MirrorDisk/UX software, which is not included in the standard HP-UX operating
       system.

       If the volume group input arguments belong to a combination of volume groups version 1.0 and 2.0 or higher, the arguments may not  be  pro-
       cessed in the order they are listed on the command line.

DESCRIPTION

       The  command synchronizes the physical extents of each mirrored logical volume in the volume group specified by vg_name	....  Synchroniza-
       tion occurs only on the physical extents that are stale mirrors of the original logical extent.

       The synchronization process can be time consuming, depending on the hardware characteristics and the amount of data.  Unless disabled,  the
       mirrors within a volume group are synchronized automatically when the volume group is activated by the command.

   Arguments
       recognizes the following argument:

	      vg_name	     The path name of a volume group.

EXTERNAL INFLUENCES

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is null, it defaults to "C" (see lang(5)).

       If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).

EXAMPLES

       Synchronize the mirrors on volume group

WARNINGS

       It is not advisable to interrupt a process.
