I've been working on this for a bit now and have made no progress. I'm
thinking this may be a bug. I loaded a drive (Not drive 0) through the
library interface and bacula shows the drive mounted (I'm stuck
waiting for a valid tape):
====
Device status:
Autochanger "T200-1" with devices:
"Drive 1" (/dev/nst0)
"Drive 2" (/dev/nst1)
Device "Drive 1" (/dev/nst0) is not open.
Device is BLOCKED waiting to create a volume for:
Pool: Default
Media type: LTO-4
Slot 5 is loaded in drive 0.
Device "Drive 2" (/dev/nst1) is mounted with:
Volume: 041772L4
Pool: *unknown*
Media type: LTO-4
Slot 2 is loaded in drive 1.
Total Bytes Read=0 Blocks Read=0 Bytes/block=0
Positioned at File=0 Block=0
====
Used Volume status:
041772L4 on device "Drive 2" (/dev/nst1)
Reader=0 writers=0 devres=0 volinuse=0
====
====
But a mount command ignores the input for which drive:
====
*mount
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
The defined Storage resources are:
1: File
2: T200-1
Select Storage resource (1-2): 2
Enter autochanger drive[0]: 1
Enter autochanger slot: 10
3001 OK mount. Device="Drive 1" (/dev/nst0)
<---------------------------- Drive 1 is index 0 - not what I
entered.
In fact, if I enter a totally invalid drive name, it still goes to drive 0:
*mount
The defined Storage resources are:
1: File
2: T200-1
Select Storage resource (1-2): 2
Enter autochanger drive[0]: fred
Enter autochanger slot: 10
3001 OK mount. Device="Drive 1" (/dev/nst0) <------------------ Still
drive index 0.
Has anyone else seen this?
I've even reconfigured the storage daemon to only use 2 drive and
eliminate a possible hardware incompatibility.
