Re: kernel 4.0.2+ ext4 corruption
Hi testers, Beware: Kernel 4.0.2 and up have an ext4 corruption bug that has not yet been fixed. I was just hit by it on my RAID0 SSD setup on a laptop. http://news.softpedia.com/news/Linux-Kernel-Plagued-by-an-EXT4-Data-Corruption-Issue-481699.shtml Thanks for heads up! Does somebody know of a RH Bugzilla ticket about this? I don't see it in there. I have filed https://bugzilla.redhat.com/show_bug.cgi?id=1223332 to track it. -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

I upgraded to 4.0.4 from a 4.0.0 build I was running. Initially everything seemed fine. The corruption occurred several hours later after I started an update run and during the run ldconfig was spitting out bad ELF errors. I corrected those that were reported, but upon a reboot it had corrupted even more files and the system was no longer bootable due to corruption to libXfont and a few other libraries. I was able to salvage the system after downgrading to 4.0.1 and re-installing rpm, yum, and a couple dozen other packages. The problem may only be related to 4.0.2 and mdadm RAID. I won't have time right this minute, but if no one else can easily reproduce it I will setup a VM with two drives and see if that's enough. -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
