Hi,
We are trying here to make backups of a Linux File Server on a DLT 8000
tapedrive, but we can not get it to streaming mode. We tried everything we
could think of, but it only streams when running 'dd if=/dev/zero
of=/dev/st0 bs=64k'. It also streams with other block sizes, but as soon as
we replace /dev/zero by anything else, it will not stream. Strange thing is
that if we dd to disk and then to tape, it streams... But if we
dd /dev/urandom to disk and then to tape, it doesn't. It's really baffling.
Since I see a lot of you are running Amanda with DLT drives, does someone
have any idea how to get the drive streaming with real data ?
Our configuration:
- Siemens F200F server, 1Ghz PIII
- Adaptec I2O SCSI Raid controller with Raid-5 set and a seperate disk with
its own filesystem
- Symbios SYM53c1010-66 SCSI controller, with only the DLT attached.
- Linux RedHat 7.1 with 2.4.18 kernel
- All filesystems are still ext2
Does anyone have a clue ?
Thanx in advance
Elmar Kolkman
