Multi-Tape error

[S�bastien GALLET]

I'm trying to backup my mp3 collection (a little more than 60 Gb) on my onstream DI-30 tape (15 Gb). The 2 first tapes work fine but when backing up on the third, amdump stops and report this :   shining    /var/datacentre/mp3 lev 0 FAILED [too many taper retries]   NOTES:   taper: tape Mp3Set1 kb 14752480 fm 1 writing file: No space left on device   taper: retrying shining:/var/datacentre/mp3.0 on new tape: [writing file: No space left on device]   taper: tape Mp3Set2 kb 14754112 fm 1 writing file: No space left on device   taper: retrying shining:/var/datacentre/mp3.0 on new tape: [writing file: No space left on device]   taper: tape Mp3Set3 kb 0 fm 0 [OK]   What does it mean ??? TIA
