Subject: [pve-devel] storage plugin volume sync during live migration
Date: Tue, 17 Feb 2026 07:06:05 -0500 [thread overview]
Message-ID: <f843995b-8f7b-493c-9183-fc5497e9610a@open-e.com> (raw)
Hi,
I have a question regarding Proxmox storage plugin
activate_volume/deactivate_volume concurrency for shared volumes.
During live migration volume can be simultaneously attached to multiple
nodes at same time.
If vm migrates from node1 to node2, activate volume on node2 will
be called before deactivate is done on node1.
This raises question regarding concurrency, a specially for sync-like
operations.
Does Proxmox have any mean to guaranty that no I/O will be performed on
node2 until deactivation on node1 is completed?
Can I/O operation take place on node2 before activation on node2 is
completed?
Best regards,
Andrei Perepiolkin
