Description

Hi all,
I used the CephFS v0.56.3 to store VMs. There're 8 nodes of my cluster, and I mount the cephFS in every node.
If I want to do live migration in my cluster, then I have to change the mode of VMs to enable another nodes to rw the VM files.
Is the CephFS can give the specified nodes the permission to write the files?
The permission of data in CephFS is in MDS, right? If so, how to operate MDS to let annother nodes can write other's file?
Any better solutions about the file permission instead of chmod file?
