[SOLVED] Problem about the snapshot location

[parker0909]

Hello All,

I am using the Proxmox 5.4 with Ceph to build the cluster and storage pool. May i know how to identify the snapshot location when we have taken the VM snapshot?
I try to check the ceph storage pool,but i can't be found any file created. Thank you.

Hi,

what do you mean with snapshot location?
if you get a list of the snapshot on image base you can use this command.

rbd snap list <image>

Thank you.
I would like to confirm any extra diskspace will be using when i taken the snapshot for Virtual machine. Thank you.

I have tried to execute the command but i got below message.
rbd: error opening default pool 'rbd'
Ensure that the default pool has been created or specify an alternate pool name

rbd snap list <image>

I have tried to execute the command again. May i know how to find the <image> value in proxmox?

Thank you.
