Hi All, I successfully bcopied a tape to disk. Then, during a subsequent bcopy from disk to tape, I got the following output:
[EMAIL PROTECTED] ~]# bcopy -c /etc/bacula/bacula-sd.conf -i FILE0002 -o MSR131L3 -v -w /var/bacula/spool VG1-LV0 Drive-1 bcopy: butil.c:283 Using device: "VG1-LV0" for reading. 30-Apr 13:36 bcopy: Ready to read from volume "FILE0002" on device "VG1-LV0" (/var/bacula/spool). bcopy: butil.c:286 Using device: "Drive-1" for writing. 30-Apr 13:36 bcopy: 3301 Issuing autochanger "loaded? drive 0" command. 30-Apr 13:36 bcopy: 3302 Autochanger "loaded? drive 0", result is Slot 28. 30-Apr 13:36 bcopy: 3301 Issuing autochanger "loaded? drive 0" command. 30-Apr 13:36 bcopy: 3302 Autochanger "loaded? drive 0", result is Slot 28. 30-Apr 13:36 bcopy: Invalid slot=0 defined, cannot autoload Volume. 30-Apr 13:36 bcopy: Wrote label to prelabeled Volume "MSR131L3" on device "Drive-1" (/dev/nst0) bcopy: bcopy.c:242 Volume label not copied. 30-Apr 16:26 bcopy: End of Volume "" at 523:8456 on device "Drive-1" (/dev/nst0). Write of 64512 bytes got -1. 30-Apr 16:26 bcopy: Re-read of last block succeeded. 30-Apr 16:26 bcopy: End of medium on Volume "" Bytes=523,512,105,984 Blocks=8,114,956 at 30-Apr-2007 16:26. 30-Apr 16:26 bcopy: Invalid slot=0 defined, cannot autoload Volume. Mount Volume "" on device "Drive-1" (/dev/nst0) and press return when ready: What does this mean? I am inclined to thing that bcopy is done. My paranoid self thinks that I forgot to rewind tape volume "MSR131L3", which caused this error. Please advise what to do next.
