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?
Sincerely,
Gour
