Thanks Brian, I added this and it seems to indicate things are working
OK without adding any sleep, so I need to keep looking.
The following is the sequence as I attempt to label a tape after having
deleted the Volume record, manually rewound the tape and done an "mt -f
/dev/nst0 weof" and placed it back in Slot 1.
Start bacula.
Do a "status" on the SD:
Device status:
Autochanger "HP_MSL2024" with devices:
"Drive-1" (/dev/nst0)
Device "Drive-1" (/dev/nst0) is not open.
Drive 0 status unknown.
Do an "automount off"
Do a "label":
Connecting to Storage daemon HP_MSL2024 at library1.sauce.co.nz:9103 ...
Sending label command for Volume "GQJ800L4" Slot 1 ...
3301 Issuing autochanger "loaded? drive 0" command.
3302 Autochanger "loaded? drive 0", result: nothing loaded.
3304 Issuing autochanger "load slot 1, drive 0" command.
3305 Autochanger "load slot 1, drive 0", status is OK.
block.c:1010 Read error on fd=5 at file:blk 0:0 on device "Drive-1"
(/dev/nst0). ERR=Device or resource busy.
3000 OK label. VolBytes=1024 DVD=0 Volume="GQJ800L4" Device="Drive-1"
(/dev/nst0)
Catalog record for Volume "GQJ800L4", Slot 1 successfully created.
Do not forget to mount the drive!!!
Tailing the mtx.log showed the "Device /dev/nst0 - READY!" up at the
same time as "3305" above then there was a pause of a few seconds,
presumably as the tape threads up and then the "Read error...."
At this point another "status" on the SD:
Device status:
Autochanger "HP_MSL2024" with devices:
"Drive-1" (/dev/nst0)
Device "Drive-1" (/dev/nst0) is not open.
Slot 1 is loaded in drive 0.
I run "mt -f /dev/nst0 status" at this point with bacula still running:
SCSI 2 tape drive:
File number=1, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x46 (LTO-4).
Soft error count since last status=0
General status bits on (81010000):
EOF ONLINE IM_REP_EN
Do a "mount" and after about 20 seconds:
block.c:1010 Read error on fd=5 at file:blk 0:0 on device "Drive-1"
(/dev/nst0). ERR=Device or resource busy.
3902 Cannot mount Volume on Storage Device "Drive-1" (/dev/nst0) because:
Requested Volume "" on "Drive-1" (/dev/nst0) is not a Bacula labeled
Volume, because: ERR=block.c:1010 Read error on fd=5 at file:blk 0:0 on
device "Drive-1" (/dev/nst0). ERR=Device or resource busy.
3905 Device "Drive-1" (/dev/nst0) open but no Bacula volume is mounted.
If this is not a blank tape, try unmounting and remounting the Volume.
Do a "status" on SD:
Device status:
Autochanger "HP_MSL2024" with devices:
"Drive-1" (/dev/nst0)
Device "Drive-1" (/dev/nst0) open but no Bacula volume is currently mounted.
Slot 1 is loaded in drive 0.
Total Bytes Read=0 Blocks Read=0 Bytes/block=0
Positioned at File=0 Block=0
Do an "mt -f /dev/nst0 status":
/dev/nst0: Device or resource busy
Which is fair, as bacula now has the device open.
So I really do not know what the drive's problem is during the "label" -
why is it busy?
Regards,
Richard
