I'm not convinced that using a rewinding tapedevice makes the tape label invalid. Anyone proof of this solution? On the other hand, a wrong blocksize (32 bytes instead of 32k bytes) can result in an invalid label. -- Paul.bijnens 11:36, 5 December 2005 (PST)

Problem

An error message from Amanda:

... not an amanda tape

Solution

Amanda requires you to label tapes before it uses them. Run amlabel(8) in order to label a tape.

You may also be able to use label_new_tapes (autolabel as of version 3.1) in amanda.conf(5) to automatically label tapes.

If, even after labeling a tape, amcheck(8) still complains about it, make sure the regular expression specified via labelstr in amanda.conf(5) matches the label you have specified, and check whether you have configured non-rewinding tape devices for Amanda to use. For example, on Linux use /dev/nrst0 instead of /dev/rst0, or /dev/rmt/0bn instead of /dev/rmt/0b. The `n' stands for non-rewinding.

If you have labeled any tapes using the rewinding device configuration, you may have to label them again (see Discussion).
