Yes, when some ceph-fuse crash , the mount driver has gone, and can't remount . Reboot the server is the only way I can do.
But other client with ceph-fuse mount on them working well. Can writing / reading data on them.
ceph-fuse --version

Can you give us package version of ceph-fuse?

Did you just mount filesystem or was there any
activity on filesystem?
e.g: writing / reading data
Can you give us output of on cluster side:
ceph -s

sorry Shinobu,
I don't understand what's the means what you pasted.
Multi ceph-fuse crash just now today.
The ceph-fuse completely unusable for me now.
Maybe i must change the kernal mount with it.
