That's pretty weird, not something I recall seeing before. When quotas are in use, Ceph is implementing the same statfs() hook to report usage to the OS, but it's doing a getattr() call to the MDS inside that function. I wonder if something is going slowly, and perhaps the OS is ignoring filesystems that don't return promptly, to avoid hanging "df" on a misbehaving filesystem? I'd debug this by setting "debug ms = 1", and finding the client's log in /var/log/ceph.
