No, there's no vchanger, bconsole or other bacula binary running, apart the
SD (and a fd).

Vchanger is version 1.0.3, and effectively no, there's no link to the loaded
media, that seems coherent anyway:
root@sdpve2:~# df | grep vchanger
/dev/sdc1 1921798404 222569068 1601537480 13%
/mnt/vchanger/49a2d36c-d620-426c-90de-de8c009aeeeb
root@sdpve2:~# ls -la /var/spool/vchanger/SDPVE2RDX/

If i try on 'drive 0' i got:
*mount storage=SDPVE2RDX
Automatically selected Catalog: BaculaLNF
Using Catalog "BaculaLNF"
Enter autochanger drive[0]:
Enter autochanger slot:
3001 Device ""RDXStorage0" (/var/spool/vchanger/SDPVE2RDX/0)" is doing acquire.
on drive 1:
*mount storage=SDPVE2RDX
Automatically selected Catalog: BaculaLNF
Using Catalog "BaculaLNF"
Enter autochanger drive[0]: 1
Enter autochanger slot:
3906 File device ""RDXStorage1" (/var/spool/vchanger/SDPVE2RDX/1)" is always
mounted.
*
*umount storage=SDPVE2RDX
Enter autochanger drive[0]: 1
3901 Device ""RDXStorage1" (/var/spool/vchanger/SDPVE2RDX/1)" is already
unmounted.
*
*mount storage=SDPVE2RDX
Enter autochanger drive[0]: 1
Enter autochanger slot:
3906 File device ""RDXStorage1" (/var/spool/vchanger/SDPVE2RDX/1)" is always
mounted.
Now i need to restart the SD...
