Hi all,
I am using IBM DAT 160 media with bacula, and I always get a tape error after a successful backup job. There were a lot of times that the tapes snapped as well. At first I thought the tapes are just defect, but the error occured so frequent that I started to doubt my bacula configuration.
I used to get this error in the logs, but couldn't find similar error in recent logs:
05-May 15:54 hpsf-sd JobId 130: Volume "set1-w" previously written, moving to end of data.
05-May 15:54 hpsf-sd JobId 130: Error: Unable to position to end of data on device "ibm-dds6" (/dev/nst0): ERR=dev.c:776 ioct
l MTEOM error on "ibm-dds6" (/dev/nst0). ERR=Input/output error.
05-May 15:54 hpsf-sd JobId 130: Marking Volume "set1-w" in Error in Catalog.
Whenever this occured, I can only relabel the tape in order to reuse it. I hope anyone can have a look on the information of the tape settings and bacula configuration provided below, and advise if there is anything that is not right.
