"mt tell" is working properly again in kernel 2.6.10-1.737_FC3. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20041020 Description of problem: Under this kernel, the MTIOCPOS ioctl to a scsi tape device fails, returning ENODEV. This was working in the 681_FC3 kernel. Version-Release number of selected component (if applicable): kernel-2.6.9-1.724_FC3 How reproducible: Always Steps to Reproduce: 1. On a system with a scsi tape device that supports the scsi READ POSITION command, and with a tape loaded in the drive, run "mt tell". Actual Results: The command reports "/dev/tape: No such device" and exits with a failure return. Expected Results: The command should print "At block nnnn." and return success. Additional info: mt-st-0.8-1 Drive is: Host: scsi0 Channel: 00 Id: 04 Lun: 00 Vendor: ARCHIVE Model: Python 04106-XXX Rev: 7350 Type: Sequential-Access ANSI SCSI revision: 02 Under kernel 2.6.9-1.681_FC3, "mt tell" works properly. I can't use 'strace' or a debugger to verify what is happening because the 724_FC3 kernel also breaks process tracing (bug 144070). I had to recompile 'mt' with some debugging printf()s to help identify the problem.
