We do that across several lpars. We run with a shared directory (DIRMAINT). We have put code in place to verify that the Linux guest is not running on another lpar.

All DASD is defined as shared. All of the linux guests have been defined as TCPIP Layer 2; so that we can easily move guests between lpars for performance/maintenance reasons. Each guests has unique mini-disks for the linux 191 and DASD swap spaces. Is it advisable to share the full volumes that these mini-disks reside on, across VM lpars; assuming of course, that a linux guest is completely shutdown and logged off of one lpar before it is restarted on another ?
