This is exactly what I'm doing right now. I trigger my script via udev
for add / remove events:
# cat /etc/udev/rules.d/local.rules
KERNEL=="xvdb1", ACTION=="add", RUN+="/root/vol_manager.pl"
KERNEL=="xvdb1", ACTION=="remove", RUN+="/root/vol_manager.pl"
KERNEL=="xvdc1", ACTION=="add", RUN+="/root/vol_manager.pl"
KERNEL=="xvdc1", ACTION=="remove", RUN+="/root/vol_manager.pl"
This auto-runs the vol_manager script (which I posted earlier), then
that script uses entries in /dev/disk/by-uuid to match up with the
vchanger.conf config.
My question now is this... For this setup, the MediaType is File with 10
slots. I have a max volume size of 40Gb. When these 10 x 40Gb slots /
volumes get full, will Bacula automatically try to create another
volume? How does it handle things when I hit 400Gb (10 x 40Gb volumes)?
