SSM create-s size - n disk name --fstype type xfs-p PV Physical volume group Volume group name /dev/sd** is that disk /root mount point


 the next thing to do is iSCSI does not mount

iSCSI implements networked storage that provides storage-side callsTarget , use the storage side to call Initiator. Targetcan provide storage space on theInitiatorResponsible for connectionISCSIequipment, inISCSI device to create file systems, and Access data, InitiatorIt looks like a hard drive.

now that the server is done, you need a client connection!!!!
 Yum install-y iscsi-initiator-utils Yum install this first
because the server binds the name, you need to change the name here.

Vim/etc/iscsi/initiatorname.iscsi

Systemctl Enable iSCSI
Systemctl start iSCSI
Start the service
