ext4 disable journal
At one high loaded web project I needed a very fast file system. I decided to use Ext4 with disabled journal (As a google:))).
# Create ext4 fs on /dev/sda10 disk
mkfs.ext4 /dev/sda10
# Enable writeback mode. This mode will typically provide the best ext4 performance.
tune2fs -o journal_data_writeback /dev/sda10
# Delete has_journal option
tune2fs -O ^has_journal /dev/sda10
# Required fsck
e2fsck -f /dev/sda10
# Check fs options
dumpe2fs /dev/sda10 |more
For more performance add fstab opions: data=writeback,noatime,nodiratime
i.e:
/dev/sda10 /opt ext4 defaults,data=writeback,noatime,nodiratime 0 0
Tested at non-boot partition ;)
