[proxmox.com, qemuserver.pm] Subject: [pve-devel] [PATCH qemu-server] vzdump: increase timeout for QMP 'cont' after backup start X-BeenThere: pve-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 27 Oct 2021 11:35:42 -0000 Since 'backup' can now work asynchronously, QEMU may not be ready to receive the next QMP command ('cont') immediately. Thus, increase the timeout, to avoid aborted backups in slow environments. There may be a deeper QEMU bug hidden under the covers here too, but at least one user reported success with simply increasing the timeout: https://forum.proxmox.com/threads/pve7-pbs2-backup-timeout-qmp-command-cont-failed-got-timeout.95212/page-2#post-426261 See also: https://bugzilla.proxmox.com/show_bug.cgi?id=3693 https://forum.proxmox.com/threads/problem-seit-update-auf-7-0.97388/ https://forum.proxmox.com/threads/error-with-backup-when-backing-up-qmp-command-query-backup-failed-got-wrong-command-id.88017/page-3#post-416339 Signed-off-by: Stefan Reiter --- PVE/VZDump/QemuServer.pm | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/PVE/VZDump/QemuServer.pm b/PVE/VZDump/QemuServer.pm index b133694..17cf724 100644 --- a/PVE/VZDump/QemuServer.pm +++ b/PVE/VZDump/QemuServer.pm @@ -867,7 +867,7 @@ sub resume_vm_after_job_start { } else { $self->loginfo("resuming VM again"); } - mon_cmd($vmid, 'cont'); + mon_cmd($vmid, 'cont', timeout => 45); } # stop again if VM was not running before -- 2.30.2
