Creating ext4 without journal

10 05 2016

Similar to ext2 but taking advantages of a filesystem desing 15 years later:

mke2fs -t ext4 -O ^has_journal /dev/sdb1

Enable writeback mode. This mode will typically provide the best ext4 performance.

tune2fs -o journal_data_writeback /dev/sdb1

Required fsck

e2fsck -f /dev/sdb1

Check fs options

dumpe2fs /dev/sdb1
