Nedd some help undersdtanding vdisk

[Bauer, Bobby (NIH/CIT) [E]]

I'm really struggling with these displays and definitions. For VM 5.4:

1) The manual says v-disk are shareable, created by the first user and deleted 
after the last user.
   If in user direct I have v-disk defined for 3 user:
        User1 has MDISK 700 FB-512    V-DISK 524288 
        User2 has MDISK 700 FB-512    V-DISK 524288 
        User3 has MDISK 700 FB-512    V-DISK 131072
   How are they shared?


2) I currently have: 
q vdisk u                                                     
VDISK USER   LIMIT IS     144000 BLK                         
Ready; T=0.01/0.01 09:39:02                                  
q vdisk s                                                     
VDISK SYSTEM LIMIT IS    3605040 BLK,    3145728 BLK IN USE  
Ready; T=0.01/0.01 09:39:13                                  

q vdisk
VDISK FAWKES   0701   131072 BLK    1 LINKS 
FAWKES   0700 R/W                                                     
                                             
VDISK NCIALPHA 0701   524288 BLK    1 LINKS 
NCIALPHA 0701 R/W                           
                                            
VDISK NCIALPHA 0700   524288 BLK    1 LINKS 
NCIALPHA 0700 R/W                           

If the user limit is 144,000 blocks, how can VDISK NCIALPHA have 524,288 
blocks, twice.

Thanks
