Hi,Shinobu
I check the /var/log/dmesg carefully again, but not find the useful message about ceph-fuse crash.
So i attach two _usr_bin_ceph-fuse.0.crash files on two clients to you.
Please let me know if you want more about other log. Thank you very much!

Ah, you are using ubuntu, sorry for that.
How about:
/var/log/dmesg
I believe you can attach file not paste.
Pasting a bunch of logs would not be good for me -;
And when did you notice that cephfs was hung?

hi,Shinobu
There is no /var/log/messages on my system but i saw the /var/log/syslog
and no useful messages be found.
I discover the /var/crash/_usr_bin_ceph-fuse.0.crash with grep the "fuse"
on the system.
Below is the message in it :
