Error in Migration

[marco114]

I am just now starting to migrate my small 8 server cluster from 1.9 to 2.2. I am starting with new hardware, so no upgrading issues.

Currently I have 2 Servers running 2.2 on Identical Hardware and setup the cluster. I have 2 virtual machines on 1 server and NONE on the other server. When I click migrate, it fails. It shows the server moved, but the data is still on the originating server. Here's the error:

I fixed the problem, turning Sharing to OFF. I had turned it on thinking it was something else. What is the purpose of this Sharing setting?

Hi Marco,
sharing mean what it's sound like: A storage which is marked as shared is visible on (all) other clusternodes - so an migration don't must copy the data, because they allready there.

Shared storage can be: LVM on SAN (iSCSI, FC, DRBD), NFS, cluster filesystems, ... (sheepdog and so on).
