Hi,

I have a cephfs subvolume ( out of 4)  with " mount path missing " issue
I think a user deleted it as it look different than regular data  to him/her

I am mounting at the group level so all subgroups are available under
same path

How concerned should I be ?
Is there a way to recreate path on a cephfs subvolume ?
what are my options for fixing it ?

Please find below details

Mounting
/volumes/projects       /projects/cephfs

Cephfs status
