Hi, i have a template and create a new kvm with this template - all is fine

  1. i increase the image from 32G to 128G - all is fine
    2 when i move the vm to my other vm server the vm will not start, it goes in panic and i must repair the partition with xfs_repair
    3 i move the vm back to the server it comes from the vm will start.

vm images are stored on a iscsi server, it is a nas. the iscsi are moutet on both servers with the iscsi client.

so the image are not moved but why will the vm not start on the other server ?
