While burning with cdrdao the HAL daemon keeps polling the drive (per default
every 2 seconds) to check for media changes. HAL expects burning applications
to lock the device using O_EXCL.
Example: Burning with growisofs or wodim:
ps -A f|grep hald
3110 ? Ss 0:00 /usr/sbin/hald --use-syslog --verbose=no
3111 ? S 0:00 \_ hald-runner
3119 ? S 0:00 \_ /usr/libexec/hald-addon-acpi
3128 ? D 0:00 \_ hald-addon-storage: no polling because
/dev/hdc is locked via O_EXCL
3130 ? D 0:00 \_ hald-addon-storage: polling /dev/hdd (every
2 sec)
3132 ? S 0:00 \_ hald-addon-storage: polling /dev/sda (every
2 sec)
22801 pts/1 S+ 0:00 \_ grep --colour=auto hald
With cdrdao:
ps -A f|grep hald
3110 ? Ss 0:00 /usr/sbin/hald --use-syslog --verbose=no
3111 ? S 0:00 \_ hald-runner
3119 ? S 0:00 \_ /usr/libexec/hald-addon-acpi
3128 ? S 0:00 \_ hald-addon-storage: polling /dev/hdc (every
2 sec)
3130 ? S 0:00 \_ hald-addon-storage: polling /dev/hdd (every
2 sec)
3132 ? S 0:00 \_ hald-addon-storage: polling /dev/sda (every
2 sec)
17528 pts/1 S+ 0:00 \_ grep --colour=auto hald
Reproducible: Always
Steps to Reproduce:
1. Burn a cd with cdrdao
2. run ps -A f|grep hald
3.
Actual Results:
HAL keeps polling drive
Expected Results:
HAL stops polling because of O_EXCL
I'm using x86, but also tried cdrdao-1.2.2. As frontend I use k3b in KDE.
