Hi, Is it possible to register local mount as a remote-fs?
I've got a rather peculiar problem with Kubernetes and Ceph: 1. kubelet creates an rbd device in /dev; 2. it mounts it to some location; 3. systemd adds local-fs.target and local-fs-pre.target to Before= and After= directives on auto-created .mount Units. Unfortunately, with that approach thing get rather messy on shutdown. Ceph RBD kernel client detects network outage (since we've already disabled the network) and stops all I/O to those filesystems, while systemd actively tries to umount them. systemd depends on umounting those filesystems, and Ceph depends on an online network to properly finish all I/O and unmount them, thus creating a kind of a deadlock. -- Andrey Klimentyev, DevOps engineer @ JSC «Flant» http://flant.com/ <http://flant.ru/> +7 (495) 721-10-27, ext. 487 +7 (960) 180-38-98
