From the document: Overview of Live Storage Migration Virtual disks can be migrated from one storage domain to another while the virtual machine to which they are attached is running. This is referred to as live storage migration. When a disk attached to a running virtual machine is migrated, a snapshot of that disk’s image chain is created in the source storage domain, and the entire image chain is replicated in the destination storage domain. As such, ensure that you have sufficient storage space in both the source storage domain and the destination storage domain to host both the disk image chain and the snapshot. A new snapshot is created on each live storage migration attempt, even when the migration fails. Consider the following when using live storage migration: You can live migrate multiple disks at one time. Multiple disks for the same virtual machine can reside across more than one storage domain, but the image chain for each disk must reside on a single storage domain. You can live migrate disks between any two storage domains in the same data center. You cannot live migrate direct LUN hard disk images or disks marked as shareable. But where do users perform online storage migrations? There seems to be no interface. _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/GRFF5WF7TEW...

The qemu and libvirtd on the KVM hosts has no error. The attached files are engine.log on the engine and vdsm.log on KVM host(where the vm is running), please refer.

Based on the engine log, there should be also some CopyImageError in the vdsm log - this would give us more context where exactly it failed. Also, given that libvirt block job failed, is there any error in libvirt/qemu log? > > > > > > > > > -----Original Message----- > From: users-bounces(a)ovirt.org <users-bounces(a)ovirt.org&gt; On Behalf Of > Vojtech Juranek > Sent: Monday, September 27, 2021 3:23 PM > To: users(a)ovirt.org; Tommy Sway <sz_cuitao(a)163.com&gt; > Subject: [ovirt-users] Re: about the Live Storage Migration > > On Sunday, 26 September 2021 14:07:01 CEST Tommy Sway wrote: > > Why always fail ? > > please provide relevant part of engine and vdsm logs _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/QCIHBSTVLVT...
