I an running kernel 2.0.30 with the BusLogic BT-958 driver (as a module)...
my backup cron job loads st.o and then removes it after the backup program
(bru) excited... the above messages occur about 5 minutes after removing
st.o ... i tend to disregard them but if anyone has some explanation as to
what they mean, please let me know!
BTW, i insert and remove the module manually rather than using kerneld (i
have 'alias char-major-9 off' in /etc/conf.modules) to make sure kerneld
does not remove the module while the tape is left unrewound for some time
(more than a minute) due to pre-backup file searches for instance... I
heard removing the module of a non-rewind tape device could possibly lead
to data loss... at least for ftape... is this still true with st? any
precision would be appreciated. thank you.
