Hi,
one more thing to try is raising the readahead setting for your raid0
device, if you haven't done that yet. If this happens to be a linux
server you could do this by echo 8192
/sys/block/md0/queue/readahead_kb for a software raid. If it's a
hardware raid, use the device name of that
Hey Frank,

thank you all for your replies. I did some testing and set Maximum File
Size to 30GB now instead of the 1GB default. Now the drive sounds much
healthier.
from what i remember the manual recommends something like 2GB Maximum
File Size for LTO2-3,

Hi Jesper,
Well, if you are sending uncompressible data, then above picture
looks like a fully saturated LTO5-drive operating at optimal speed
since the 140MB/s are for compressible data to the drive.
thanks for your quick answer. So the sound of the drive

Hello
from what i remember the manual recommends something like 2GB Maximum
File Size for LTO2-3, so i guess LTO5 would be served well with 4GB.
You can check a performance of different tape file size (EOF marks) using a
btape utility. I found 8GB

Hi, no, it is not normal. Except that you have too small Maximum File Size
setting. I have 8 GB, which means atleast one file per

Hello,
maybe a beginners question from me. I setup bacula and I'm very
impressed about it. I have a LTO-5 drive and use data spooling to a
6x1TB RAID0 array before streaming to disk. But thoughput is maybe low.
The drive writes while reading at 140MB from disk for 7-8 seconds, stops
for 4-5
