mtx's Introduction

This is a clone of the original MTX project as found on https://sourceforge.net/projects/mtx/

The project appears to be abandoned, the home page is down, and the latest changes stem from almost a decade ago (as of November 2019).

The mtx folder contains the actual build files, while mtxweb contains an archive of their webpage.

I'll be holding onto this repo for the time being. Any future bug reports or issues should be logged here. I'll do my best to make the necessary changes, but I make no promises.

If you'd like to help out, reach out.

mtx's Issues

Wrong slots / barcodes

Hi,

I have a strange behavior when running the status command. I got a Quantum Scalar i3 with 25 LTO-8 tapes in ascending order in slots 1-25. While the web-interface of the library reports the barcodes correctly mtx -f /dev/sg2 status sees tape 16 in slot 24, tape 24 in slot 25 and tape 25 in slot 16. If I remove tapes 24 and 25, tape 16 still in slot 24 and slot 16 is empty. If I only remove tape 25, tape 16 is in slot 24 and tape 24 in slot 16. Maybe a small table is more descriptive:

Inserted tapes slots
16, 24, 25 25, 16, 24
16, 24 24, 16
16 24
24 16
24, 25 16, 24
25 16

All other slots are not affected at all.

Here's the output with full loading

$ sudo mtx -f /dev/sg2  status
  Storage Changer /dev/sg2:1 Drives, 25 Slots ( 0 Import/Export )

      Storage Element 25:Full :VolumeTag=BAR024L8

When I activate the DEBUG_BARCODE and increase the output of the DataBuffer I can also see the mixed up allocation.

Probably this is not a problem of mtx but a bug in the scalar i3 firmware. I just wanted to report this here and maybe you already know about that.
