Well, no filesystem is impervious to hardware problems. Even if you have metadata and journal checksumming enabled, which isn't a default still, there is no guarantee. Gist is, simple mount option -o journal_checksum for journal checksumming. For full metadata checksumming you need e2fsprogs 1.43. Current in F21 is 1.42.11-2, and it doesn't support mkfs.ext4 -O metadata_csum,64bit. https://ext4.wiki.kernel.org/index.php/Ext4_Metadata_Checksums Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
