Hi all,
I have an issue when changing between tapes, which provides the following message:
> Error: Re-read last block at EOT failed. ERR=block.c:1029 Read zero
> bytes at 818:0 on device "LTO5" (/dev/nst0).
I tried btape
*test : all tests succeeded
*autochanger : all tests succeeded
* fill :
I get a labelling error
Error: 08-Oct 20:16 btape JobId 0: Wrote label to prelabeled Volume "TestVolume2" on device "LTO5" (/dev/nst0)
Something that makes no sense
Error: 08-Oct 20:18 btape JobId 0: Ready to
read from volume "TestVolume1" on device "LTO5" (/dev/nst0).
but more importantly I still get
Error: block.c:1029 Read zero bytes at 0:0 on device "LTO5" (/dev/nst0).
However, the test seems happy:
The last block on the second tape matches. Test succeeded.
Could you please suggest some troubleshooting ideas ?
Best,
Gnewbee
P.S.:
end of full btape fill output:
