First of all, I am newbie SE.
Now I am trying to use two disks attached to one instance.
One is only for OS, the other for logs data, etc.
So I launched Compute engine with SSD PD 20GB(/dev/sda) and SSD PD 100GB(/dev/sdb).
I partitioned /dev/sdb to 1 extended partition within 3 logical partition using fdsik command.
After that I made file system and mounted it.
[johndoe@my-instance ~]$ df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 16G 0 16G 0% /dev
tmpfs 16G 0 16G 0% /dev/shm
tmpfs 16G 8.5M 16G 1% /run
tmpfs 16G 0 16G 0% /sys/fs/cgroup
/dev/sda2 20G 2.1G 18G 11% /
/dev/sda1 200M 12M 189M 6% /boot/efi
/dev/sdb5 20G 45M 20G 1% /MY_PARTION_svc
/dev/sdb6 20G 45M 20G 1% /MY_PARTION_app
/dev/sdb7 50G 53M 50G 1% /MY_PARTION_log
tmpfs 3.2G 0 3.2G 0% /run/user/1000
And I want to make custom image from this vm (including disk partitioning configuration) for Autoscaling.
So I created a custom image and started a new instance using that image, but when I looked at the boot process through the serial console, the mount failed.
Looking at the serial console, there is a process of mapping the device UUID and directory to the /etc/fstab file in the partitioning operation, but this will be different for every instance, so it seems like an error that occurs.
Then, for an instance that uses an additional partitioned disk, I am wondering how to create a custom image with the packages I want installed.(for autoscaling).
English is not my mother language and I am not familiar with Linux, so I am wondering if my question was delivered correctly.

Before going any deeper in the OS/hardware specifics I tried to reproduce your issue.
I've set up a new CentOS 7 instance with 20GB system disk and additional 100GB disk. Then I logged in and created 1 extended 100GB partition with three logical ones:
Then I stopped the VM, created its image (with default settings). Then based upon it I created a new VM instance (process created a new 20GB system disk and another 100GB for data). It booted OK and I was able to log in via SSH. Partitiones were visible in
fdisk.The only difference between my example and your case is that you've mounted your paritions before creating an Image. I didn't.
Try creating an image again and a fresh VM from it - what you've experienced may have been some bug so try again.
