I'm not sure I understand what you are saying here (I often read
things the wrong way).
Are you saying that after you've done a number of tape writes
each of a certain buffer size (which would be ?), that
when you have in total written out around 1 to 2 Gb that you
get this error ?
[I initially was thinking you were referring to the problem of
large tape block writes of 1-2Mb and you might need to change
max_sg_segs for the st module as described in
cmd/xfsdump/doc/README.xfsdump]
Are there any messages in the system logs from the st driver ?
Were you using xfsdump ?
