dir to zfs migration error

[GesaInfo]

Hi, I have to transfer a VM from one node to another, the problem is that if I try to perform the migration, it tells me ERROR: storage migration for 'SSD:102/vm-102-disk-0.raw' to storage 'ZFS' failed - cannot migrate from storage type 'dir' to 'zfspool'. how can I solve it?

'SSD:102/vm-102-disk-0.raw' to storage 'ZFS' failed - cannot migrate from storage type 'dir' to 'zfspool'

I believe the raw file image stored in the directory type storage cannot be stored as a VM image to the zfspool type storage.

See this, & note 1

You try to migrate from node A with storage dir to node B with storage zfs? This may be impossible. Normally, you have a shared storage, so that it's just a simple click an takes a second or use at least the same storage type e.g. ZFS on both machines in order to have replication and easier migration.

A workaround could be to mount a nfs or cifs shared storage to both nodes (or to the cluster in this example) and migrate the VM first from storage dir to storage shared, then to the other node and then to the zpool.

I will try this solution. Will I convert to raw or qcow2?

Hi,
dir->zfs is not implemented for offline migration yet, but you can use online/live migration.

That does not matter, yet I'd go with qcow2, which is potentially smaller due to thin provisioning.
