Hi, I recently installed some fresh CentOS 6.5 machines and it took only about 20 minutes until the file system (ext4) was broken. And with "broken" I mean, that the system wasn't able to find vital system libraries any more! I were able to reproduce it on highly different systems: - A fresh installed CentOS 6.5 64 Bit on a virtual machine (KVM) - A system which I installed some weeks ago (also a KVM machine) and did a "yum update" which upgraded to kernel 2.6.32-431.5.1.el6. - A fresh installed CentOS 6.5 64 Bit on native hardware on a RAID 5 assembled with mdadm - A CentOS 6.4 system installed some months ago on native hardware with mdadm RAID 5 The last system wasn't able to boot after the upgrade and crashed with several kernel panics which I can show as a screenshot if there's any interest - but the display resolution was quite low so there are not many helpful information :-( Actually, I assume that there's anything broken with the new kernel or at least the kernel module for ext4 file system. You can reproduce it by just doing a "yum update" and rebooting the system. If it comes up, reboot it again and manually do an offline filesystem check - or just do some writing activities on the disks. Is it just me? I don't use any 3rd party repositorys and it blows my mind that no one else seems to notice...!
