I can not enter the folder, even I type chmod 755 cephfs, no use

Code: 
root@g8kvm37:/mnt/pve#
root@g8kvm37:/mnt/pve# cd cephfs
-bash: cd: cephfs: Permission denied
root@g8kvm37:/mnt/pve# ls -al
ls: cannot access 'cephfs': Permission denied

Is the secret correct?
compare this two secrets

Code: 
ceph auth get-key client.admin
cat /etc/pve/priv/ceph/cephfs.secret

Reboot the node is ok. But I still have many node over 10 nodes have this problem. Reboot is the only option?
 
Try to unmount the dir.
It gets mounted automatically again if there are no kernel problems.
If there are hanging processes in the kernel you have to reboot all nodes.

Umount the folder is ok, Thank you very much !!!!!!



Another question, do you know if ceph has ackage updated, does it need the reboot the node ?
 
No there is no need to reboot the node.

You have to restart the ceph services to get the latest version running.
This can be done over the GUI.
A node reboot is only necessary if a new kernel is available.

One more question, do you know why no HA enable(no grooups, no resource) , restart the corosync could make the cluseter reboot ?
 
There is a discussion on the developer list about this.
I guess the problem is resolved soon with an update.
 
I had the same issue,

unable to activate storage 'cephfs' - directory '/mnt/pve/cephfs' does not exist or is unreachable

is redicious. i can upload file to it from GUI.

I found some node "cephfs" is ? on it. i used this to umount and it will auto mount then fix:
Code: 
umount -l /mnt/pve/cephfs
