Hello, after performing testing of my HP Ultrium 448 drive with:
amtapetype -f /dev/nst0 I got the following result: Checking for FSF_AFTER_FILEMARK requirement Applying heuristic check for compression. Wrote random (uncompressible) data at 21864712.2580645 bytes/sec Wrote fixed (compressible) data at 50207857.7777778 bytes/sec Compression: enabled Writing one file to fill the volume. Wrote 203994431488 bytes at 22522 kb/sec Got LEOM indication, so drive and kernel together support LEOM Writing smaller files (2039939072 bytes) to determine filemark. define tapetype unknown-tapetype { comment "Created by amtapetype; compression enabled" length 199213312 kbytes filemark 207 kbytes speed 22522 kps blocksize 32 kbytes } # for this drive and kernel, LEOM is supported; add # device-property "LEOM" "TRUE" # for this device. However, when comparing the above result with the entries at http://wiki.zmanda.com/index.php/Tapetype_definitions#Hewlett-Packard_Ultrium_448 I see that all of 'em have: "filemark 0 kybtes", while I got "filemark 207 kbytes" What do you think, iow. shall I use the one arrived after amtapetype testing?
