Error while migrating an LXC from one node to another

[Francesco Piraneo G.]

Hi all,
this is what's happens while I'm migrating an LXC container from one node of my datacenter to another:

The error is repetitive.

I try to dig by myself what's happening but an help is appreciated.

TIA

hi,

packet_write_wait: Connection to 192.168.1.210 port 22: Broken pipe

seems like the ssh connection between nodes is getting interrupted.

can you ssh between the nodes? it should work without any user interaction (try like ssh nodename or ssh nodeip from node1 -> node2 for example)

seems like the ssh connection between nodes is getting interrupted.

I don't know why, the ssh connection gets interrupted!
Now the issue is solved.
