Tape driver is a Quantum DLT7000, with DLT IV media. Native capacity should be 35Gb, and I'm running Amanda with host based compression, and compression switched off on the drive. The tapetype definition is:-
define tapetype DLT-7000 { comment "Quantum Bluedisc Digital Linear Tape 7000" length 35000 mbytes filemark 8 kbytes speed 1250 kbytes }
A listing of the output size to tape:-
Output Size (meg) 31855.4 31855.4 0.0 Original Size (meg) 66922.0 66922.0 0.0 Avg Compressed Size (%) 47.6 47.6 --
It would be nice if you showed a few lines further in the report where the drive bumped into end of tape. IN the Notes secion you see something like:
NOTES:
taper: tape ARCHIVE-079 kb 33504128 fm 31 writing file: No space left on device
taper: tape ARCHIVE-080 kb 34156192 fm 20 writing file: No space left on device
(From my report, writing on "35 Gbyte AIT-1 tapes"). It shows my tapes are not really 35 Gbyte the 35 Gbyte is usually measured in marketing terms where K=1000 and M=1000*1000 and G=1000*1000*1000. Amanda uses the K=1024, M=1024*1024, G=1024*1024*1024.
If you hit consistently into eot at about 70-80% of the normal capacity, I strongly believe you still have compression enabled. If it's only now and then, and at different capacities, maybe cleaning the tapedrive helps.
Running amtapetype takes about 5 hours if you, give it a realistic estimated tapesize:
amtapetype -e 35g
(and amtapetype will tell you too, if you still have compression enabled).
