Detaching file storage from a VM
-
Unmount the file storage from the VM:
-
Connect to the VM over SSH.
-
If you added a line to the
/etc/fstab
file for automatically mounting file storage to the VM at startup (for example, when attaching storage to a VM), delete the line. -
Run this command:
sudo umount <mounting_path>
-
To check that your file storage has been unmounted, run this command:
df -T
As a result, there should be no
virtiofs

If you don't have Terraform, install it and configure the Yandex Cloud provider.
Set the
allow_stopping_for_update
parameter totrue
on your VM, if you have not done it yet.-
Open the Terraform configuration file and delete the fragment with the storage description:
Sample storage description in the VM configuration in Terraform... resource "yandex_compute_instance" "vm-1" { name = "test-vm" platform_id = "standard-v3" zone = "ru-central1-a" filesystem { filesystem_id = "fhmaikp755gr********" } ...

Apply the changes:
-
In the terminal, change to the folder where you edited the configuration file.
-
Make sure the configuration file is correct using the command:
terraform validate
If the configuration is correct, the following message is returned:
Success! The configuration is valid.
-
Run the command:
terraform plan
The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.
-
Apply the configuration changes:
terraform apply
-
Confirm the changes: type
yes
in the terminal and press Enter.
-
You can check that the storage has been detached from the VM using the management console
or this CLI command:yc compute instance get <VM_name>
Use the detachFilesystem REST API method for the Instance resource or the InstanceService/DetachFilesystem gRPC API call.
- In the management console
