Currently nfs is not supported by checkpointing. Moreover IMHO any external mounts prevents online migration.

But In my previous post where i wrote what i have problem
checkpointing a VE with internal only mounts, i was suggested to
use bind mounts to solve the problem

Quote:

To migrate this VE you can umount nfs partiotion, migrate it to target node and then mount nfs again.

And if there are processes accessing the nfs mounted fs, i would not want to stop them too, since it would be almost the same as
complete shut down of VE, and it's not really live migration anymore.
NFS is a very commonly used feature, is there a chance that NFS checkpointing implementation will get a high priority in the openvz TODO list?

Thanks
Alex
