Thomas Krenn recommends creating ext4 partitions like:
mkfs -O ^64bit,^metadata_csum -t ext4
what does this mean?
does this have anything to do with the y2038 problem?
"A user should be able to turn on this feature at mke2fs time simply by specifying -O metadata_csum. Because the 64bit feature allows arbitrarily large block group descriptors that are large enough to enable crc32c for the bitmaps, mke2fs should warn the user if the feature set is metadata_csum,^64bit when it becomes the case that the 64bit feature has been tested thoroughly."
what is recommended? move to btrfs?
