We are having recuring problems with shoeshining. Our tape is a iomega
ditto max, and it runs off and on. It has been working for months, but now
it will not. We get errors from cron that say the drive, as /dev/nqft0, is
in use. Sometimes this is becuase a tar thread will not properly exit for
days. Sometimes the modules will not unload (even when the tape is rewound
and ejected) and a system reboot will fix it (this is a server, reboots
are hell). Right now, if I issue a 'ftmt -f /dev/nqft0 status' it will
shoeshine until I kill the process. It has gone overnight like this.
In conf.modules, I have this:
alias char-major-27 zftape
options ftape -f ft_fdc_driver=ftape-internal,none,none,none \
ft_tracings=3,3,3,3,3
options zftape -f ft_major_device_number=27
options ftape-internal -f ft_fdc_fc10=0 ft_fdc_mach2=0 ft_fdc_base=0x200 \
ft_fdc_dma=0 ft_fdc_rate_limit=3000
I have tried with ft_fdc_rate_limit of 2000,3000,4000 to no avail.
Our cron is this:
ftmt -f /dev/nqft0 rewind
ftmt -f /dev/nqft0 reten
ftmt -f /dev/nqft0 rewind
tar czf /dev/nqft0 / -X /exclude.backup.txt
and the exclude excludes /proc/* /dev/* and /tmp/*
Any ideas are greatly appreciated.
