Solaris live upgrade - how to check if a fs is shared or not

Hi all,

1) how do i check which FS(filesystems) in the current active PBE are shared and not shared with the ABE (alternate boot env) ?

is doing lufslist and comparing between the 2 BEs the only option ?

2) when doing a luactivate -s (synchronize), does the synchronization go both way or 1 way only ? (e.g. from the current BE to the ABE only)

Regards,
Noob

NAME

       lutab - list of boot environments

SYNOPSIS

       /etc/lutab

DESCRIPTION

       The  file /etc/lutab is a list of the boot environments (BEs) configured on a system. There are two entries for each BE. These entries have
       the following form:

       BE_id:BE_name:completion_flag:0
       BE_id:root_slice:root_device:1

       The fields in the lutab entries are described as follows:

       BE_id	       A unique, internally generated id for a BE.

       BE_name	       The user-assigned name of a BE.

       completion_flag Indicates whether the BE is complete (C) or incomplete (NC). A complete BE is one that is  not  involved  in  any  copy	or
		       upgrade operation. A BE can be activated or compared only when it is complete.

       0	       Indicates first of two lines.

       BE_id	       As described above.

       root_slice      Designation of the root slice.

       root_device     Device on which the root slice is mounted.

       1	       Indicates second of two lines.

       The lutab file must not be edited by hand. Any user modification to this file will result in the incorrect operation of live upgrade.
