--- Comment #2 from Ravishankar N <ravishankar at redhat.com> ---
I'm able to reproduce the issue on a plain 2x1 distribute volume also. Mounting
a client on the node which is up hangs up until the network.ping-timeout value.
After changing it from the default 42 to 20 seconds, even umount seems to hang
for that time:
