Bug#576511: drbd8-utils: Ships with violent default actions for various drbd fault, conditions - may cause dataloss.

2011-05-23 Thread Lionel Sausin 
Dear maintainers,

To be clearer, the reboot is ordered in catastrophic conditions where
data loss will happen on the DRBD device whatever you do, because DRBD
has lost all the usable storage device - this is much like unplugging a
hard drive.
So rebooting is probably a good option when DRBD is vital to the system,
and that's what DRBD is supposed to be.

My humble opinion is that the default is acceptable, but it's certainly
surprising for new users.

Maybe the choice could be left to the user at installation time :
debconf could ask something like We advise you configure DRBD to reboot
the system immediately when a serious problem arises that would cause
I/O errors.
Would you like DRBD to be configured to reboot in order to avoid I/O
errors ?
[Yes] / No

Lionel Sausin.

Bug#576511: drbd8-utils: Ships with violent default actions for various drbd fault conditions - may cause dataloss.

2010-04-05 Thread Tim Small 
Package: drbd8-utils
Version: 2:8.3.7-1
Severity: normal

/etc/drbd.d/global_common.conf ships with the following lines enabled:

handlers {
pri-on-incon-degr /usr/lib/drbd/notify-pri-on-incon-degr.sh; 
/usr/lib/drbd/notify-emergency-reboot.sh; echo b  /proc/sysrq-trigger ; reboot 
-f;
pri-lost-after-sb /usr/lib/drbd/notify-pri-lost-after-sb.sh; 
/usr/lib/drbd/notify-emergency-reboot.sh; echo b  /proc/sysrq-trigger ; reboot 
-f;
local-io-error /usr/lib/drbd/notify-io-error.sh; 
/usr/lib/drbd/notify-emergency-shutdown.sh; echo o  /proc/sysrq-trigger ; halt 
-f;

!!

This might sort of be alright if the box is dedicated to drbd, but it
still might not be.  echo b  /proc/sysrq-trigger is particularly
nasty, as it will force a reboot without syncing filesystems.

Tim.
