Hello
Well recently I have to do a partition biger then 2TB, because I wanted to use all drive for backup.
Because fdisk won’t work, well I figure it out that I have to use parted
so here we go.
parted /dev/sdb
the output will be something like
GNU Parted 2.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted)
after tis we create a label
(parted) mklabel gpt
Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue?
Yes/No? Yes
After this we specify the unit that we want to use
(parted) unit TB
We tell parted to use all space
(parted) mkpart primary 0 -0
And the result
(parted) print
Model: ATA ST3000DM001-9YN1 (scsi)
Disk /dev/sdb: 3.00TB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Number Start End Size File system Name Flags
1 0.00TB 3.00TB 3.00TB linux-swap(v1) primary
(parted) quit
Now we format the partition
mkfs.ext4 /dev/sdb1

180 days, whichever comes first. Use tune2fs -c or -i to override.
The result
mkdir /backup
mount /dev/sdb1 /backup/
df -h
