Problem encounter after upgrading OpenSuSe

I guess when you upgraded from OpenSuSE 12.3 to OpenSuSE 13.2 you just allowed it to use BTRFS as its default root file system which replaces the old ext4 file system because that’s the actual cause. BTRFS is the short term used for B-tree file system. It is a GPL-licensed copy-on-write file system designed for Linux. Its development started in 2007 at the Oracle Corporation.

The on-disk format of the BTRFS file system has already been marked as stable as of August 2014. Bad news is, the kernel that comes with it has a known fault that breaks a number of software using mmap() and pre-allocated files. The best way to fix it is to use the old and trusted ext4 file system as your root file system.

In case you already used BTRFS, you should upgrade your kernel to at least 3.17.2 which supposedly would fix the problem. Please visit OpenSuSE Kernel Repositories to download the kernel. Another way of fixing it without upgrading your kernel is to downgrade your file system to ext4. To properly do it, visit OpenSuSE 13.2 Don’t Use BTRFS.
