Bug#401934: st.o module does not allow 1MB blocks
Package: linux-image-2.6.18-3-amd64
Version: 2.6.18-7
This same issue also applied to kernels 2.6.16-2-amd64-k8-smp and
2.6.17-1-amd64-k8-smp, I believe as well.
When trying to read or write a tape with blocks of 2048*512 bytes using
the st module, the application (either dd using bs=1048576 or tar
using "--blocking-factor=2048) quits with an error that says that the
device is "busy". If you try reading/writing with smaller blocks
things work fine.
The problem is that I have hundreds of tapes written (using earlier
kernels) using 2048x512B blocks....
Was there a Debian-specific patch that limited the block size in order
to conserve memory usage, for example? If so, could that please be
removed or else tweaked to allow at least 1MB blocks? Most of the
tapes that I have, have been written using recent versions of RHEL.
Here is my uname string:
Linux uller 2.6.18-3-amd64 #1 SMP Mon Dec 4 17:04:37 CET 2006 x86_64
GNU/Linux
I'm running Debian unstable as of 05 Dec 2006
libc = 2.3.6.ds1-8
Thanks a bunch,
Scott
PS: I submitted this previously with incorrect package/version names.
Sorry about that....
