Alibaba cloud console > Cloud server ECS > Click storage and snapshot in the left menu > Click cloud disk > Click more on the corresponding cloud disk > Click mount
Click mount and a dialog box will pop up .
Select the server you want to mount in the target instance . Click execute mount . Alicloud will prompt you that it is being mounted , Now wait for alicloud to mount the cloud disk .
Wait until the mount succeeds , get into Linux Command interface , input fdisk -l command

On hard disk /dev/vdb You can find it below devicce boot yes /dev/vdb1
Format hard disk ：mkfs.ext3 /dev/vdb1
mkdir /data0 mount /dev/vdb1 /data0
Write partition table
echo '/dev/vdb1 /data0 ext3 defaults 0 0' >> /etc/fstab
<> two , Common errors
You may encounter the following errors when mounting :
[root@i4qr4iaaq ~]# mount /dev/vdb1 /root/relationship/ mount: /dev/vdb1 is
write-protected, mounting read-only mount: unknown filesystemtype '(null)'
The disk must be formatted before mounting , It is possible that you have not formatted the old disk mount . implement
mkfs.ext3 /dev/vdb1 You can format the disk , Then follow 1 Just follow the steps in .
