Public bug reported: 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/disk/diskfilter.c:886. I've also filed a bug upstream: http://savannah.gnu.org/bugs/?41582 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. ** Affects: grub2 (Ubuntu) Importance: Undecided Status: New ** Patch added: "0001-Fix-double-free-when-using-LVM.patch" https://bugs.launchpad.net/bugs/1330963/+attachment/4133236/+files/0001-Fix-double-free-when-using-LVM.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1330963 Title: grub-probe: double free or corruption in some rare cases To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1330963/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
