Hello,
I try to replace full backups by virtualfull backups.
I use a virtual autocharger( disk changer, also tried vchanger)Â with 10 slots
and 2 drives
the second virtuallfull hangs waiting for a volume that is already mounted (
idle) in another drive
This behaviour is 100% reproducible ( bacula 5.02 ).
i test my setup with the following sequence:
A/ incremental ( transformed to full )Â OK stored in pool incr and volume1
B/ Virtuall full OK stored in volume2 and pool vfull
C/ incremental OK appended to Volume1 pool incr
DEVICE STATUS return the folluwing result:
Device status:
Autochanger "usb-changer" with devices:
"usb-changer-drive-0" (/tmp/bacula/drive0)
"usb-changer-drive-1" (/tmp/bacula/drive1)
Device "FileStorage1" (/tmp/t1) is not open.
Device "usb-changer-drive-0" (/tmp/bacula/drive0) is mounted with:
Volume:Â Â Â Vol1
Pool:Â Â Â Â Incr
Media type:Â File
Slot 1 is loaded in drive 0.
Total Bytes=967,680 Blocks=14 Bytes/block=69,120
Positioned at File=3 Block=0
Device "usb-changer-drive-1" (/tmp/bacula/drive1) is mounted with:
Volume:Â Â Â Vol2
Pool:Â Â Â Â vfull
Media type:Â File
Slot 2 is loaded in drive 1.
Total Bytes=838,656 Blocks=12 Bytes/block=69,888
Positioned at File=1 Block=0
====
Used Volume status:
Vol1 on device "usb-changer-drive-0" (/tmp/bacula/drive0)
Reader=0 writers=0 devres=0 volinuse=0
Vol2 on device "usb-changer-drive-1" (/tmp/bacula/drive1)
Reader=0 writers=0 devres=0 volinuse=0
====
D /run a virtual full
bacula chooses a new volume for that backup ( volume 3 )
for whatever reason bacula wants to load volume2 ( the previous virtual full )
in drive 0 but the volume is already sitting idle in drive 1
then the backup hangs and bacula asks the opetrator to mount volume2 on drive0
how can i tell bacula to check if a volume is already mounted before trying
to load it in another drive ??
