Bug Description
[SRU justification]
System does not boot in degraded mode on second disk. This is systematic when system is localized in french (fr_FR.UTF-8)
[Impact]
Unable to boot system in degraded mode
[Fix]
Backport uptream fix :
http://
[Test Case]
- Install system with system disk as RAID1 with french localization.
- Remove first disk (/dev/sda) from the system
- Boot the system.
Without the patch, grub will loop forever and the system will not boot.
With the patch, the system boots normally.
[Regression]
None expected. This fix is already in present in Debian Wheezy, Ubuntu Trusty and Utopic.
[Description of the problem]
When a RAID1 system is degraded (e.g. unplug /dev/sdb, leaving obnly /dev/sda), grub-pc properly enters prompt but system is reset as soon as one attemps to boot OR one enters the command-line and issue the 'ls' command.
This bug is known (and presumably fixed) to Debian: http://
Shortly put: adding the 'GRUB_TERMINAL=
I believe this bug is critical because it shows up only when a disk fails but remains latent on a healthy system.
Cheers
