Create iSCSI volume with Parted and Format with XFS

Posted on by Jordansphere

This is a follow on from the following post: http://www.jordansphere.co.uk/add-iscsi-target-with-multipathing-in-rocky-8/

In this guide I will be formatting a 100TB XFS volume

List block devices

lsblk

Output

Run Parted on volume

parted /dev/mapper/VEEAM-REP01

Label the partition

mklabel GPT

Create XFS filesystem at 100% size

mkpart primary xfs 0% 100%
quit

Make mount point

mkdir /BACKUP

Make XFS filesystem on partition

mkfs.xfs /dev/mapper/Veeam_Repo_01p1

Mount filesystem

mount /dev/mapper/VEEAM-REP01p1 /BACKUP

Edit FSTAB and add following line

vi /etc/fstab
/dev/mapper/VEEAM-REP01p1    /BACKUP xfs     _netdev,x-systemd.requires=iscsi.service        0 0

Note:

_netdev tells fstab this is a network device

x-systemd.requires=iscsi.service confirms the order of startup. This should mean the order is network -> ISCSI -> Mount and then the same in reverse when shutting down.
