Application scenarios

If the client has attached the LUN created by HBlock, the LUN will be automatically mounted after the server is booted up.

Prerequisites

The Linux client has attached the LUN created by HBlock.

Here's how

Use the command lsblk -f on the Client to view the file system information of the mounted device and find the UUID corresponding to the file system:

[root@client ~]# lsblk -f
NAME        FSTYPE       LABEL UUID                                 MOUNTPOINT
sda         mpath_member                                      
└─mpatha                                                      
  └─mpatha1 ext4               7269eef6-e401-454a-acb4-503d33337f21 /mnt/disk_mpatha
sdb         mpath_member                                      
└─mpatha                                                      
  └─mpatha1 ext4               7269eef6-e401-454a-acb4-503d33337f21 /mnt/disk_mpatha
vda                                                           
├─vda1      swap               9e33bd6f-c68c-41c7-95c8-703f4fe8c3d4 [SWAP]
└─vda2      xfs                a83f4fdc-2ea1-4fec-a1e2-a42016ce0afe /
vdb                                                           
└─vdb1      ext4               74296a9e-8cfd-4708-89b1-08086f71175b 
vdc                                                           
└─vdc1      ext4               a9fedea4-391e-4d2a-8824-c9a3a6853394

Add the LUN mounting information created by HBlock in the /etc/fstab file, and the LUN can be automatically mounted the next time you start the computer.

UUID=7269eef6-e401-454a-acb4-503d33337f21 /mnt/disk_mpatha  ext4    defaults,_netdev   0 0

Storage Resource Reutilization System

The Linux Client can directly mount the LUN created by HBlock after restarting the server
