Description

This is probably related to some of the mysterious "device or resource busy" failures to umount in tests.

Just found that when running a ./ceph-fuse in a vstart cluster, and kill -9ing it, it didn't terminate. The ceph-fuse process had gone away, but the "mount -o remount" process hadn't.

The `mount` process isn't killable either, one has to go and hit the /sys/fs/fuse/connections/<id>/abort file before it will terminate.

Unclear if there's much we can do about it, but we should at least document it.
