Hmm that seems consistent with this report which mentions 3.1.5 as last working kernel: http://comments.gmane.org/gmane.comp.file-systems.ext4/30575 So somehow this only effects ext4 on DM (it's THE common factor in all reports) and fsck seems incapable of seeing the error (and thus repair it.) -- Sander > -Kees -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
