i think this happens because bacula releases the USB device
after the job.
after the job i have this device state:
Device "BB-USB1" (/media/USB) is not open.
Configured device capabilities:
EOF BSR BSF FSR FSF EOM REM RACCESS !AUTOMOUNT LABEL !ANONVOLS ALWAYSOPEN
Device state:
!OPENED !TAPE !LABEL !MALLOC !APPEND !READ !EOT !WEOT !EOF !NEXTVOL !SHORT
!MOUNTED
so it is !MOUNTED, thats why the unmount do nothing.
first i have to mount the device again:
*mount storage=USBStorageBB1
*status sd=JBBB
Device "BB-USB1" (/media/USB) is not open.
Configured device capabilities:
EOF BSR BSF FSR FSF EOM REM RACCESS !AUTOMOUNT LABEL !ANONVOLS ALWAYSOPEN
Device state:
!OPENED !TAPE !LABEL !MALLOC !APPEND !READ !EOT !WEOT !EOF !NEXTVOL !SHORT
MOUNTED
now i can successfully execute the unmount and remove the usb stick .....
why is the device released after the job?
is there any way to avoid this?
