ext4
Provision partition with Ext4
First, delete the existing partition and create a new
Linux partition using fdisk
:
fdisk /dev/sdb
Assuming /dev/sdb
is the external hard disk. Use d to delete the
partition and use n to create a new partition. 83 is the ID of the native Linux
partition.
Then, format the partition with ext4 using mkfs
which is just a unified
front-end for the different mkfs.fstype
tools:
mkfs -t ext4 /dev/sdb1
Finally, use tune2fs
to adjust some parameters:
tune2fs -m 0 /dev/sdb1
tune2fs -L bakap01 /dev/sdb1
The -m
option is for adjusting the percentage of reserved blocks.
The reserved blocks are used by privileged processes which is by default 5% of
the hard disk size. Since I'm using the external hard disk solely as a storage,
I set this to 0 so I can also use those 5% for storage. The -L
option is for
labeling the filesystem.
