Bug Description
There is small bug in grub2 in trusty, that causing grub-probe to fail in some rare cases.
I've got system with follwing scheme:
GPT (4 HDD):
1) 128MB Free space, bios_boot flag
2) MDADM RAID10, /boot, ext3
3) MDADM RAID10, LVM vg0 (for /, /home, etc)
4) MDADM RAID10, LVM vg1 (data partitions).
In this case grub fails with:
glibc detected *** ./grub-probe: double free or corruption (fasttop): 0x0000000000838760 ***
Cause of this behavior is grub-core/
I've also filed a bug upstream: http://
but it's still not closed and bug is present in Ubuntu 14.04.
I'm attaching my vision of fixing this bug here. Thoguh, there maybe a better way to fix this.
