Hello,We are running a Octopus cluster however we still have some older Ubuntu 16.04 clients connecting using libcephfs2 version 14.2.13-1xenial.
From time to time it happened that the network was having issues so the clients lost the connection to the cluster. But the system still thinks the mount is running and it has to be restarted manually. In some cases we even had to restart the complete machine because it would refuse to unmount.
I also attached a dmesg log so you can see the systems behaivior. How do you deal with such issues?
