├─zstack-root 253:0 0 1.8T 0 lvm /
└─zstack-swap 253:1 0 31.3G 0 lvm [SWAP]
sdb 8:16 0 3.7T 0 disk
├─sdb1 8:17 0 1000G 0 part
│ └─zstack-root 253:0 0 1.8T 0 lvm /
└─sdb2 8:18 0 1000G 0 part /zstack_data
２.查看系统挂载
[root@10-3-0-169 ~]# df -Th

tmpfs tmpfs 6.3G 0 6.3G 0% /run/user/1000
tmpfs tmpfs 6.3G 0 6.3G 0% /run/user/0
3.查看物理卷 pvdisplay，pvs，pvscan
[root@10-3-0-169 ~]# pvdisplay
-bash: pvsdisplay: command not found
[root@10-3-0-169 ~]# pvdisplay
