How to: CentOS 6 - Creating Larger than 2TB Partition with PARTED
https://www.atlantic.net/cloud-hosting/how-to-centos-6-creating-larger-2tb-partition-parted/
Fdisk doesn't work with partitions larger than 2 TB. Use parted instead.
# parted -a optimal /dev/sdb
> 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? Y

Skriva ISO-avbildningar till USB
$ sudo dd if=veeam-recovery-media-3.0.2.iso of=/dev/sdf
$ sudo dd if=proxmox-ve_6.1-1.iso of=/dev/sdf bs=1M
Montera externa USB-enheter
Av nån anledning monteras externa usb-enheter av root på Ubuntu. Detta gör att vanliga användare inte kan skriva till enheten.
Enligt webben kan detta bero på vem som formatterar den externa enheten. Se de två alternativen nedan.
Alternativ 1
$ sudo id -u sorin
1000
Avmontera usb-enheten med din filhanterare eller "umount /media/sorin/sorin.500GB".
OBS! Nästa kommando kommer att radera hela enheten!
$ sudo mkfs.ext4 /dev/sdc1 -E root_owner=1000:1000
Notera att sdc1 kan vara något annat på ditt system!
När klart, montera som vanligt.
Alternativ 2
$ sudo chown -Rv sorin.sorin /media/sorin/
changed ownership of '/media/sorin/sorin.500GB/lost+found' from root:root to sorin:sorin
changed ownership of '/media/sorin/sorin.500GB' from root:root to sorin:sorin
changed ownership of '/media/sorin/' from root:root to sorin:sorin
Montera som vanligt efter ägarändringen.
Det är lite oklart om denna ändring kommer att följa med, om man monterar den externa usb-enheten på en annan dator. YYMV...
